I use this as storage for my mini Mac 2 and iPad Pro. I do videos and cAn transfer files from one device to another to work on them. Love the portability and light weight. It is perfect for my needs. I would definitely recommend it.

I been using this for a year now, truly amazing if you’re looking for external storage. Super fast

When I connected to my Windows 11 Pc it wouldn’t show up, I went into device management and hard formatted to work. But that wasn’t my only issue. When this SSD connects it makes my computer SUPER slow for some reason. Shutdown won’t work when it’s plug in. Accessing the folders will crash explorer/ folders. But on my MacBook M5 max it works fine.

Would have worked but had an outdated device that didn't allow me to properly use or use it is all on my computer. Requires a certain usb or thunderbolt port to even work. Make sure you know the requirements before making your purchase.

I needed a storage solution for my photography business. The external drive is fast and secure.

The equipment arrived on time, I haven't tested it 100% yet but everything seems to be going well.

Needed more storage space for photos so I purchased the SanDisk SSD external hard drive! Never had any problems with their products!

Product works as intended but power draw is higher than other drives. At one point other accessories disconnected since the power allocated to a bus is often 15w

Wanted something for business and family pictures for storage and it is great

Fast and reliable device! I tried all the other brands but nothing compares to this speed demon

This a very nice and fast hard drive. It works great with my iMac.

It works well as thunderbolt 3 external speeds on m1 MacBook.

Love the protection against dropping my cell phone.

Fast & excellent buy. Highly recommended esp. for mac users.

Great product and works great with iPhone 15 pro max.

A top-end SSD solution. It wasn't the manufacturer's fault that the iPhone 15 Pro Max rejected it as incompatible, but that was a disappointment. Although I had purchased it for that, re-purposing it as the external drive of my MacBook Pro to receive iPhone video was still a win. The real reason for four stars instead of five was that it gets quite hot even when sitting there quiescent doing nothing.

Works great! I can store a lot of things on it! Honestly

when I first plugged it into the mac it wouldn't recognize it hmmm but kept trying eventually it worked

The SanDisk Pro-G40 external SSD is one of the best, if not the best, external SSD on the market right now. Its perfect for videographers, vloggers, photographers, or anyone else who wants high performance storage in a portable form factor that can attach to a thin/light laptop, like a MacBook Pro for Thunderbolt3 speeds. If you have a newer Intel laptop, you can also take advantage of the Thunderbolt3 speeds, otherwise, PCs over USB-C will fall back to USB-C speeds of 3.2 Gen2x1. Thunderbolt3 offers up to 40Gbps over USB-C, while USB 3.2 Gen2x1 offers only 10Gbps. In real world performance that's about 2700/1900MB/s Read/Write for TB3 and 1000/1000MB/s for USB-C. Pretty big difference so you'll want to make sure your laptop supports TB3 to make the most use out of this SSD. My MacBook Pro has TB3 so it supported the full bandwidth, the main difference for TB3 and TB4 is better minimums on TB4 but the max is still 40Gbps. The beauty of the SanDisk Pro-G40 however isn't just in raw transfer speeds, which are great, but the random I/O and read/write speeds are fantastic for using this drive as a scratch disk. That's really important for large files because storage is at a premium on MacBook Pros and you're not going to want to keep a lot of large files on your local laptop drives if you can help it. So for work flow, I typically connect my Mirrorless digital camera directly over USB-C to my MacBook Pro, then I'll manipulate the files using MacOS and copy over the video files I want to edit directly to the SanDisk Pro-G40. The files never stay on my MacBook. The transfer speed is as fast as the source (Nikon Z30 reading at 150MB/s from SD card), so pretty slow overall, but once it gets to the Pro-G40 that's a different story. From there, I can edit the video files using LightRoom, PhotoShop or Premiere and its all as silky smooth, responsive, and FAST. Its as if the files were on my local SSD o my MacBook Pro. This also saves a lot of Read/Writes on my local drive which can cause the SSD to wear over time, although I've never had a drive fail or lose capacity over this. But if you can offload that wear/tear to an external, why not? Once I'm done editing photos or videos, I can then upload the finished, much smaller edited files first over Wi-Fi to the cloud. Then I can either delete the RAW footage or transfer those to a NAS directly over USB-C as well. The build quality on the Pro-G40 is excellent as well, rugged and premium looking with silver accents and a rubberized finish on one-side so it doesn't mark up or scuff hard surfaces you set it on. The top side is metal and helps the drive stay cool by dissipating heat. The drive is heavy and water resistant and looks and feels amazing. Very good SSD and the 2TB storage is massive. This alone is like a $600 option on the latest MacBook Pro (2TB to 4TB) and you can use this drive again and take it with you if you upgrade again. You can also move it around from laptop to PC or NAS as mentioned so you don't have to deal with slower transfers over WiFi or even NIC (1Gbps vs. 10Gbps). So yeah the Pros far outweigh the cons!

I was in need of an SSD with a higher than 1TB capacity for use with my MacBook Pro for extended storage and file transfer. I was familiar with the standard SanDisk line of SSDs but was very curious about this Professional series and thought I'd try out the 2TB model. What an excellent decision. The SanDisk Pro-G40 SSD is a dream. First, It's comes pre-formatted in APFS, but can be reformatted for Windows usage as well. It's tiny, very solid, well-built but I truly love its 2700MB per second read speed and its 1900MB per second write speeds! My new MacBook Pro is Thunderbolt 4 ready and this SanDisk drive has Thunderbolt 3 built in, which provides up to 40Gbs transfer speeds...and I see it. I plugged it into my MacBook Pro with the included short Thunderbolt 3/USB 3.2 Gen 2 cable. I transferred 500GB of data from my older SSD to this new drive and it only took a few minutes. I was very pleasantly surprised! Since Im using this drive as an external where I store all my Photoshop/Illustrator and Dimension files, I need that speed. So far, I have had no issues with write/read speed to and from it and saving working files seems instantaneous now. It also is compatible with USB C speeds of 10Gbps in case your laptop/desktop is not Thunderbolt 3 capable. The drive is also tiny at 2.3"w x 4.3"l x .5"h. It's very light and is made from what appears to be aluminum. It's a nice dark slate color and the entire base and sides are rubberized, so there's no slippage or fear of it easily being knocked of my work surface. But, even if it does get knocked off, this drive can handle a 9' drop per SanDisk's specs. It's IP68 rated so it's highly dust and water resistant and it can handle up to 4000 pounds of crush pressure. This thing is a beast! The only gripe I have with this drive is the activity LED. It flickers constantly while it's on and is distracting as I work. I've since covered the LED with black electric tape and annoyance solved! My previous SSD drive had a solid lamp versus flickering and it never bothered me. Overall, I am extremely happy with this drive and if you are in the market for a heavy-duty, external drive that is extremely fast, this is a no brainer. I very highly recommend!
