Customer Ratings & Reviews

If you are looking for a rugged Thunderbolt 3 external drive- look no further. This is the one. One M2 MAC write speeds exceed those advertised and are at roughly 2500 Mbp/s

Excellent Disk I connected it to a Mac mini M2 and it gave me a speed of 2700 mb/s writing.. I had read a review that said that it only reaches 1000 mb/s but I discovered that changing the cable for a Thunderbolt 4 reaches 3000 mb/s and if it does not reach that speed you just have to exchange the ends of the cable and ready normally the cables bring a mark make sure it is Marce look up.

I had to download the instructions manual off the Internet . It wasnt recognized by windows ,it was formated for Macbook from factory . I had to go to device manager and follow instructions from sandisc website to format the drive for windows. Not very easy if you don't know how . Anyhow it's working and thunderbolt is working ,it's as though the drive is connected inside the laptop .

Definitely has the transfer speed. Didn’t get recognized by Mac until reformatting tho

Very fast speeds. Ready for storage and work. I use for music production!

I am using this external drive for Logic Pro project files for music production and to store large sample libraries for virtual instruments and it works well for those purposes. I copied many GB of files from another SSD in one minute or less.

Good produce, i use it everytime when editting video or photo on my mac

Sandisk's latest Pro G40 External SSD brings Thunderbolt 3 speed along with durability and portability. With external storages becoming smaller, lighter, and more reliable, what distinguishes each is their speed and features. Sandisk's external SSD supports Thunderbolt 3's technology and allows for faster transfer speeds through its USB 3.2 Gen 2 interface. Having an SSD over a standard HDD gives you faster read speeds and portability (among other features), but having a drive that supports Thunderbolt 3 provides quicker speeds when using it with a computer or device that also supports Thunderbolt 3. When not using it with a device that supports Thunderbolt 3, the USB 3.2 Gen 2 speeds will also keep read and write transfer speeds quick. In one simple test I ran using my Mac's Thunderbolt 3 interface, I copied 10 half gig video files and it took less than 3 seconds for the copy to complete. When testing the transfer speed with more files (2,500 files of pictures and videos), it was able to transfer them in 11 seconds! Since the Pro G40 is formatted in APFS (for use in Mac computers), it cannot be used simultaneously on Windows computers. This is not a defect but how all drives operate (needing a file system, in this case APFS). If you prefer to use the drive with a Windows computer, it would need to be reformatted and can be done so using Windows’ built in Disk Management utility. Keep in mind, if you reformat the drive, all data on it will be deleted and it is recommended for the data to be copied onto another device temporarily. In addition to the super quick transfer speeds, the rubber type enclosure (on the sides and back of the enclosure) of the SSD offers durability being able to survive drops of up to almost 10 feet as well as having a crush resistance of two tons (4,000 lbs)! While I don’t expect to run over it with my car, it is nice knowing that if I dropped it and it gets run over, my data will survive. Along with drop and crush protection, the G40 is also water resistant up to 1.5 meters (a little under 5 feet) and dust resistant (IP68 rating). As for the cons, I’m a little disappointed it doesn't include the latest iteration of Thunderbolt, which is 4. This would help for future proofing, competition against similar drives, and the speed that Thunderbolt 4 adds. The Sandisk Pro G40 2TB version, unlike the 1TB version, did not get too hot in my testing and can say I didn’t experience any performance drops while using it throughout my day. Overall, the Sandisk Pro G40 is a great external drive for long term or short term storage of your data. It is wickedly fast and is great when moving over lots of files or when you’re simply attempting to load up files (such as when video editing or loading up a stored video game). I would recommend this to anyone looking to find a small, durable, and quick external SSD drive for storing and backing up their data.

SanDisk PRO- G40 is a solid-state drive (SSD) designed for high performance computing, content creation and gaming. It uses 3D NAND technology to offer supercharged speeds for both read and write. Its unique ultra-rugged enclosure and NVMe 1.3 interface makes this device stand out from the competition. What’s in the box: Pro-G40 SSD, Thunderbolt(40Gbps) cable, Quick start guide. It measures 4.36in x 2.28in x 0.47in. Its longer and thicker than T7 touch(see picture) due to its ultra-rugged design with metal core wrapped with silicon bumper edges. This design is great for protecting the device from accidental drops and keeping the internals cool. Its one of the fastest portable SSD that was tested ever with Thunderbolt 3 and is designed for professional who need great performance and speed. It uses DRAM DDR4 and SanDisk 96-layer BiCS4 for memory with sequential read speed of 2700MBps on thunderbolt 3 / 1050 MBps on USB and 1900 MBps on thunderbolt 3 /1000 MBps on USB 3.2 Gen2. What sets this from other brands is this one, has a got a very high level of reliability and durability as its mean time between failures is rated for up to 2 million hours. It uses lower power consumption due to its 3D NAND technology and has a status light indicator on the front for ease of use. It also uses a large SLC cache to improve performance during heavy work loads. It works best on thunderbolt3 devices and has dual-mode interface compatibility for convenient, multi device versatility (supports USB 3.2 Gen 2 & TB3). It does come formatted APFS and need to be reformat if using on Windows 10 or 11 device. Since it has a cooling aluminum core and built to last, it is rated for IP68 dust/water resistance, 3m drop protection and 4000lb crush resistance to withstand all elements for professional use. Device is very portable, weighing around 120 grams. Comes with a 5-year warranty. During our testing, this 2TB is the top performer in the test in Thunderbolt mode. We recently got Samsung T7 touch 2TB and this one beats in performance, speed and is great for gaming. We tested using DiskBench storage benchmark tool to transfer 40GB data to backup my files that contains videos, pictures, pdfs, office documents. This drive is excellent and outperforms other drives. Pro: Ultra-rugged design, Dual mode interface compatibility for multi-device versatility, high speed performance for both read/write, IP68 dust/water resistance. Cons: High price compared to other SSDs on market, shorter transfer cable length. Overall, the Sandisk Pro G40 SSD is an excellent choice for anyone who needs a high-performance drive for heavy workloads, games, content creation or any demanding tasks that is highly reliable and durable with generous warranty.

The SanDisk Professional PRO-G40 drive is a content creator's dream. Offering reliability, aesthetics, performance, and protection all in one package, I can honestly say this is my go-to drive from now on. It is built for ever-changing work life, has speed and space for editing/recording projects, and adaptability for iOS and PC users. Thunderbolt 3 and USB-C 3 handle iOS and PC operating systems flawlessly when you reformat the drive as exFAT. The drive looks good, has rubber for both grip and shock absorption, and a dual interface with a single cable, what more can I say? Inside this really solid housing, you will find a WD _Black SN750E 2TB drive which is super speedy! Performance is snappy and handles my professional workload without issue. I edit BlackMagic RAW (bRAW) on Da Vinci Resolve and Premiere Pro between Mac and PC without issue. The drive gets hot after prolonged use and gets warm just being plugged in without any load. Nevertheless, it handles the workload just fine. iOS offers the best speeds using Thunderbolt 3 after moving a 137GB bRAW file in under 4 minutes. On PC, performance was significantly reduced moving the same file in almost 5.5 minutes. Thunderbolt 3 interface is definitely the best way to go here with better read and write speeds. I highly recommend the drive to anyone wanting a drive that can take a drop, who is on the go, and demands performance for efficient editing time!

This external drive is great. It uses Thunderbolt 3/ USBC port. The case itself is durable. It feels like it has a a rubber skin on it so it will not slide around the table. It comes with USBC/Thunderbolt 3 cable. I have been using it with my 2021 Apple MacBook Pro M1 and 2023 Apple Mac Mini M2. I use it mainly for Final Cut Pro. I am able to edit and playback 4K footage taken from my Apple iPhone 14 Pro Max and Sony ZV-E10 mirrorless digital camera. I have no issues at all. There are no frame loss during playback. The enclosure can get a little warm during usage but not much. It is also silent. After formatting, you have 1.72TB of usable space. I have it formatted as APFS (Apple File System). Something to note. I have noticed it "slower" with my MacBook Pro. I used Blackmagic speed test app. It reads at 1702 MB/s and writes at 1744 MB/s. On my Mac Mini, it slightly performs better at 2400 MB/s both read and write. Either speeds will handle my 4K footage. It performs fast enough. My only complaint is the cable that it comes with is short. It works fine if you don't mind it right on the side of your computer. But I like to have my peripherals behind the computer/laptop. It can get in the way if all your ports are on one side of the laptop and you have a wired mouse. I wouldn't take a star off for that. This is a great drive.

As a professional for very long time, I have used multiple external hard drives over the years. But I have to say this Sandisk Professional PRO-G40 SSD 2TB External drive is easily one of the best I ever had the pleasure of using this is a high-end external storage device designed to cater to the needs of professionals who require fast and reliable data transfer speeds. First of all the design is sleek, modern and very rugged. This ssd light-weight form factor makes it very easy to carry around with me wherever I go, whether Im at work or traveling to different locations, with a rubberized finish it provides a secure grip and protects the device from scratches and damage. The SanDisk Professional - PRO-G40 SSD has two connection options, Thunderbolt 3 and USB-C. Thunderbolt 3 provides the fastest data transfer speeds, while USB-C provides more backward compatibility with a wider range of devices. This model comes with a latest 40Gbps Thunderbolt 3 /Gen 2 USB 3.2 compatible cable, which makes it easy to transfer large amounts of data without much hassle. The PRO-G40 SSD boasts impressive performance that is ideal for professionals who require fast data transfer speeds. This device is equipped with latest Nonvolatile Memory Express (nvme) tech, which delivers the highest throughput with fast read and write speeds. This device claims that it has a read speed of up to 2700MB read and 1900MB write through Thunderbolt 3 and 1050MB read & 1000MB write with USB 3.2 Gen 2, in reality most of the times it achieved that speeds which makes this SSD a great choice for transferring large files quickly. But what really sets this external SSD apart is its durability. As someone who's always on the move, my gear takes a lot of beating. But the PRO-G40 is built to withstand extreme temperatures, drops, and even water and dust. With this ssds rugged nature I never have to worry about my precious files being lost or damaged, no matter where my adventures take me. This SSD is compatible with devices, including laptops, desktops, and gaming console with Mac and Windows operating systems via reformatting. This makes it a versatile storage solution for professionals or gamers who need to transfer files across different devices And let's talk about capacity, With a vast 2TB of storage space, you can store lots photos, videos, and projects in one place without sacrificing speed or reliability. I never have to worry about running out of storage space or juggling between multiple external storage drives. It's a real game changer for my multiple storage requirements and saves me so much of time and hassle. SanDisk PRO-G40 comes with a 5-year limited warranty. Which gives me a peace of mind for very long time knowing that if anything were to happen to this ssd drive, I can count on manufacturer to make it right whenever needed Overall I'm extremely impressed with this SSD which built with A Grade materials with water and dust protection and has a sleek and compact design that is easy to carry around. It's a very powerful, most reliable, and durable storage solution that makes my life as a professional so much easier. If your in the market for a versatile external hard drive, I highly recommend this giving a try.

TLDR: Build quality and performance is excellent. Extremely fast speeds which save you a ton of time. Much faster than traditional sata SSDs. This NVMe is worth it and an easy recommendation. I tested it on PC, Mac, and iPad. COMES WITH: The SSD and a small thunderbolt 3 cable. BUILD QUALITY: Excellent. I’m assuming a metal encloser. But it is hard to tell as it is covered in a matte rubber that feels high quality. There is an LED that lights up to show it is powered. It is compact and thin. Gets slightly warm to the touch during heavy use. Otherwise isn’t warm. You can open the encloser with specialized screws. I didn’t do that. Overall, looks and performs at a high level and I am very satisfied. OTHER NOTES: When I plugged it in it immediately came up and asked if I wanted to use it as a Time Machine back up. Also, immediately showed on my MacBook and my iPad Pro. Additionally, when plugged into my Windows PC it showed up, but in order to retrieve or add data I had to format the drive. MY TESTING: - 44.72 GB worth of data. That was mixed with normal computer files (pictures, videos, settings, word documents, etc.). The sata PNY was 1TB and probably 30% of it was used. Where the SanDisk NVMe was fresh 2TB. 1.95 TB of that drive are available on Mac. MacBook Air M1: - PNY CS900 SSD connected via USB 3.0 to Dock w/ 3.0 USB to USB-C to Mac/PC/iPad Thunderbolt Port: - SanDisk Pro-G40 connected via USB-C to Thunderbolt Port: Transferring FROM Portable SSD to Mac: 44.72 GB via PNY sata SSD = 3:28 min 44.72 GB via SanDisk NVMe SSD = 1:00 min (or 2:28 min faster). Transferring TO Portable SSD from Mac: 44.72 GB via PNY SSD = (Didn’t test as I would have had to format) 44.72 GB via SanDisk SSD = 0:54 seconds. iPad Pro Gen 5 12.9 inch 256 GB: Same setup as above: Transferring FROM Portable SSD to iPad: - 44.72 GB via PNY SSD = 5:28 - 44.72 GB via SanDisk SSD = 2:38 - For both SSD’s it appeared to be repeatedly disconnecting while transferring. Which slowed it down tremendously. Then it would lock on and transfer crazy fast then slow again. Unsure if this was an SSD issue or iPadOS. I’d go iPadOS. Especially, since it happened on both. Transferring TO Portable SSD from iPad: - 44.72 GB via PNY SSD = (Didn’t complete as would have to format) - 44.72 GB SanDisk SSD = 1:00 min - Didn’t have the issue above where it appeared to be connecting and disconnecting multiple times. Windows PC: Same setup as above. But cannot confirm Thunderbolt port. As I think it is USB-C 10 GB/s port instead of 40 GB/s. The laptop that I know has thunderbolt ports is currently broken and not working so couldn’t test it. Transferring FROM Portable SSD to PC: - 44.72 GB via PNY SSD = 2:48 - (Max Speed of 311 MB/s which it sustained the majority of the time) - 44.72 GB via SanDisk SSD = 1:39 - (Max Speed of 759 but constantly fluctuated from 500 – 700 80 percent of the time) - I did have to format and delete everything on the drive first in order for Windows to be able to use it. Otherwise I could see that it was attached but couldn’t do anything with it. As all options were greyed out. Transferring TO Portable SSD from PC Gen 3 SSD: - 44.72 GB via PNY SSD = 6:08 - (Max speed of 275 MB/s which it sustained about 40% of the time. Then dipped to about 88 MB/s). - 44.72 GB via SanDisk SSD = 1:44 - (Max speed of 605 MB/s which it sustained for 90% of the time. It had some dips but then would go back up to speed. Which is normal behavior. The other filled up the buffer and then throttled.) - I did have to format and delete everything on the drive first in order for Windows to be able to use it. Otherwise I could see that it was attached but couldn’t do anything with it. As all options were greyed out.

The PRO-G40 supports both Thunderbolt 3 and USB-C 3.2 Gen 2. It's small and doesn't require a power supply which makes it easy to carry on the go. The speeds are the highest I've seen from an external SSD. With such high speeds, the SSD can heat up, so SanDisk built the main part of the enclosure to help with heat dissipation. This added a little extra weight to it, but in my testing, it did keep the SSD at a reasonable temperature. It ended up getting warm, but not hot. In the box: In the box you get the SSD and a Thunderbolt 3/USB-C cable. Construction: The enclosure is well made. The enclosure is aluminum and the sides and bottom are surrounded by non-slip rubber. There is an activity light on the top and a Thunderbolt/USB-C port. The cable isn't loose in the port, so no worries about it easily being disconnected. Speed: I was able to very high speeds from it when connected to my Mac's Thunderbolt 3 port. It comes formatted in APFS. Speed tests with it formatted APFS reached over 2300MB/s for both read and write. I reformatted the partition in exFAT so I could also use it on both my Mac and windows system. On my Mac, with it formatted exFAT, I saw similar speeds for read and write. With the PRO-G40 being small and the read/write speeds being what they are, you shouldn't have any problem editing RAW video (ProRes RAW, BRAW, etc.) directly off the SSD. This is a simpler alternative to upgrading your laptops internal SSD in order to get the high read/write speeds typically seen in internal SSD. Now you can simply add one of these and drop it into your laptop bag for on-the-go video editing. This is also a good option for those of you who are gamers and need additional storage with high throughput. In my use of the PRO-G40, I haven't come across any downsides to it. Its incredibly well constructed and has such a small form factor that I'll always have this with my laptop when out shooting video. I would recommend considering the PRO-G40 if you need a small fast external SSD or if you are needing to edit video off an external SSD while out in the field.

I've been using the SanDisk Professional G40 SSD for the last few days to edit personal vlog videos and photo editing. I can honestly say that I am very impressed with the speeds of this drive when connected to my 14" MacBook Pro with M1 Pro chip. You'll need thunderbolt 3 or better to get the most out of this drive so keep that in mind! I recently purchased a mirrorless camera that is capable of shooting 6K video and 4k 60 at full sensor size. I'm no Pro when it comes to editing, it's a hobby for me. So I can only mention how it performed when using it with iMovie. I imported a couple of video clips at 4K 30fps, about 5 gb worth of video onto the drive to edit into a short 3 minute video. It processed and exported the 3 minute video in seconds! I looked away for a moment, 10 seconds tops and it was done! I couldn't believe it. The exported file was Apple ProRes. I typically don't edit and share long format videos, so I can't comment on how long it would take to process and export say.. a 20 minute video. But I think it is safe to say that (if you are using one of the new MacBook Pros with Apple silicon and have thunderbolt 3/4.. it will only take a couple of minutes to do the work for you. The drive is very rugged, it has a rubber silicone feeling back and a metal plate on top. I did not test its water resistance lol.. But it is ip68 rated, so it should survive a drop into a shallow puddle or some mud if you're clumsy and for some reason juggling this drive outside. My only complaint is that I wish the included USB C cable was just a little longer. I've attached some test speeds and it seems to have exceeded the advertised write speeds. Would I recommend this drive? Most definitely. If you're a content creator, You know that time is very valuable when it comes to editing. This drive will save you lots of time over its lifetime. I highly recommend it for anyone looking to edit photos and videos. Professional or hobbyist. It comes with a 5 year warranty, that is great for an External SSD.

I use the "SanDisk Professional - PRO-G40 SSD 2TB External Thunderbolt 3 and USB-C NVMe Portable SSD to back-up my systems on my home computers. gaming SSD in gaming computer, partitioned to 200g C drive, the rest to 2nd partition to store my games and whatnot that don't need backing up. running easeus todo backup of about 150g system, highest compression, to that gaming SSD 2nd partition (quoted at around 400 MB/s), and then doing the same onto the Crucial X8 (quoted at around 1200 MB/s), I do find that this X8 does complete in about 1/4 of the time. About 7 minutes or so to make a complete system backup onto the X8, plugged into a USB 3 port, and about 8 minutes to run the restore when booted off a partitioned sector on the X8 running the easeus todo emergency flash restore app. For anyone interested, things like virtual memory and all your steam games can be done on 2nd partition on your gaming SSD drive because they don't need to be backed up. having virtual memory set to a large max size, same min and max size, means no fragmentation of other files, and having that virtual memory on extra partition means it doesn't get backed up or anything, meaning your backup drives don't need to be as big. shrink your system partition to as small as it can comfortably handle, and you can easily back it up several times onto a drive like the X8. I use easeus todo backup home lifetime license for each of 3 computers, and use the settings image, 1 time only, system. incremental seems to be somewhat unreliable recently, and the speed of full system backup onto the X8 means not really an issue to do full system backup, then reboot to restore to make sure it works, and then copy to 2 other drives to make sure there are extra copies. ~PROS~ ~Blistering speeds over a Thunderbolt 3 connection ~Extremely rugged ~Handsome design ~Thunderbolt 3 cable included

***STANDOUT FEATURES:*** 1.) It actually works as advertised. Copies and transfers are fast. 2.) It feels quality in hand. 3.) It looks expensive. 4.) Build is rubberized, weather resistant and rugged. ***SPEED:*** Copying files from the internal drive is very fast. Like any drive, longer file transfers with multiple file sizes varies the speed wildly. Regardless, this is the fastest external drive I have used. Whatever the drive is inside, there is a very good interface board to make everything work at blistering speeds over Thunderbolt 3. You'll max out the USB 3.2 Gen 2 rating (1050MB/s read, 1000MB/s write) every time. ***HEAT:*** External NVMe drives can get very hot depending on their enclosure. This can slow down performance and decrease user comfort drastically. The way this enclosure is built, you will have minimal issues with heat, even with prolonged use. ***CROSS PLATFORM USE:*** The drive I received was configured for use with Mac out of the box. That means the APFS file system. If you wanted to use it cross platform, you could reformat it to exFAT. If you want encryption cross platform, you'll have to fork out money for third party software on Mac (and format it as NTFS). ***CAMERA USE:*** This would be an ideal choice for videographers. IP68 rating means excellent dust, water, 3 meter drop resistance. You could have this on your camera rig and quickly offload footage to your editing computer. ***CONCLUSION:*** The only downside here is price. Ultimately, however, with high reliability, speed, looks and quality, you get what you would expect for the money.

The SanDIsk PRO-G40 is a must have for anyone, this thing is built like a brick and is ridiculously fast. I used this connected to my Mac Mini M1 with 16 GB of ram and the devices not only delivers its stated read speed but over delivers on its write speed. This is a rarity when comes to products, usually manufacturers give you best case scenarios which the average user isn't able to duplicate. Now I know the numbers or speed/bench mark test are one thing and actual use is a totally different thing so I put it through its paces with some video editing and used it on 3 different edits making sure they were identical (speed/transitions/affects/color adjustments/text/audio). After the test I am happy to report that the PRO-G40 was only slower by 3 seconds on a 3 minute export and it was 1 second slower on a 6 min export and 8 seconds slower on a 15 minute export in comparison to the local NVMe on the Mac mini. Basically the PRO-G40 is just as fast as the internal NVMe and as they say the best products are the ones you dont even know your using. Besides the PRO-G40 delivering on what it promises in terms of raw performance it is a super solid made product that feels like it can stand up to the elements or being tossed around in your bag or by your kids. I would highly recommend this to anyone because with the amount of data we have for work/business/personal not only do you want a product that is build to last but you want to be able to access that data that is saved as quickly as possible.

The SanDisk Pro-G40 SSD is an excellent, portable drive for on-the-go and home needs. I use Adobe Premiere Pro for video editing on my Mac, and I was very well pleased with the speeds when I needed to open or transfer files. One thing that's often overlooked is the ability of external hard drives to sustain speeds. The speed rate I hit when I first connected the drive only curtailed off by a few 100 mbps after working for at least 45 minutes which is pretty good in my opinion. One of the best things that the PRO-G40 does is save you from yourself. I've been guilty of carelessly dropping my backpack down to the floor that happens to contain my drive. I did perform a water resistance and drop test. I can attest that the SSD was still functional. I did not have the ability to conduct a crush resistance test near the limit specified in the description, but the grade A+ build quality caused me not to doubt the claim. The only complaint that I can register for the drive is that it is slightly warm after about 1-2 hours of usage, but it is cooler than the average external SSD and cell phone especially. Also, this drive is more optimized (as it relates to speed) for Mac devices, but will work properly for Windows computers. Overall, I feel that my data is safe, protected, and that my editing workflow is unimpeded.

The SanDisk Pro-G40 Thunderbolt SSD is an external drive for those who need uncompromising performance from their storage devices. Connected to my M2 MacBook Air, performance is simply astonishing and up to 50% faster than the internal SSD that my Mac came equipped with from Apple! Thunderbolt enables PCIe performance so it shouldn't be a surprise that the drive can hit 2700 MB/s reads. What I love about the PRO-G40 is that it also offers regular USB-C 3.2 backwards compatibility for use with devices that don't have open Thunderbolt ports. It does come with a short TB3 cable in the box which is a plus. As a byproduct of having internal NVMe level performance, the SanDisk Professional drive is a great choice for those who work on UHD+ video projects. My previous external SSD was a USB-C 3.2 model which seemed pretty fast at 900 MB/s R/W performance when I got it about 2 years ago. However, when working on video projects I often found myself copying the input files to my internal storage when possible, so I was working off my internal drive with its higher performance and maximizing the speeds when it came time to export the finished video to my larger external SSD. With the PRO-G40, this extra step is eliminated as the drive is both larger and faster than my internal storage. Especially when stitching dozens of small clips, this drive can easily handle anything you throw at it. The PRO-G40 is also built like an absolute tank and can easily survive being tossed in a camera bag for an outdoor trip. The case seems to offer substantial heat dissipation capability as well. I say this because it gets warm quite quickly and doesn't seem to drop performance by much when hitting it with lots of writes. Finally, the drive comes formatted to work with Macs for Time Machine and is thus incompatible with non Apple devices out of the box. I've left mine formatted as APFS as I haven't used Time Machine for a few years, but I may eventually reformat for compatibility with my Android phone and Windows PCs. Just something to keep in mind if you plan to use this drive with a Windows computer.
