Customer Ratings & Reviews

Excellent speed and portability! The X9 is a fantastic external drive for backups and large file transfers. The compact design makes it easy to carry, and the USB-C connectivity ensures quick, reliable performance. A solid choice for anyone needing fast, external storage

Great storage Unit. Very light small and very fast. It doesn`t get hot like many others and always working very well. Much better than the last one X6

This drive is tiny and fast! Was able to backup my files in no time at all. Easy to store and take with you on travel trips for work. Adds almost aero weight! Price was insane because it was on sale! Great work Best Buy and Crucial!

'm a filmmaker, and I do my own editing, so I'm in constant need of LARGE hard drives to transfer projects to different production departments, as well as deliver films to distributors. These small but huge portable hard drives are perfect for what I need. Reliable with a great price.

Love this drive. It’s small but practical. plugged into my laptop and recognized right away.

It's small lightweight and didn't get too warm when plugged into my MacBook Pro for long periods of time. I just wish I could transfer things from this SSD drive to my Micro SD card when connected to my MacBook Pro. Transfer speeds on my Samsung 360 book 3 is not as advertised but I had three transfers coming out of this thing and it handled the transfers without burning up. I call that a win. Even if it was not as fast as advertised.

It's TEENY TINY but performance is BIG! Use it with my s21 wayy more than my t7. The one with the rubber outer shell~ ...feels light as a feather and if your cord is new/stiff enough it can hold it up abit lol Stash it in a ziplock with the rest of my cords whenever make a Disney trip (=

This hard drive is fast enough to record our live stream in HD through OBS. If you are looking for a very fast recording hard drive, this is it!

Nice product, fast transfer times, compact and easily portable device, feels lightweight but that is probably a good thing if you want to take it with you daily.

Works great. Very nice and compact. Fast download speeds.

Great build quality and transfer speed, and budget-friendly compared to competitor brands like Samsung.

I like this device but it has limited connections available. I had to go back to a slightly older laptop. There is no way to connect via USB port so I couldn't open saved files I had to use a port and an adapter. Other than that, it is very light, small, and holds lots of data.

Great add on to my MacBook Air! I use it to store Parellels and the programs I run on parellels.

The bundled USB cable does not work at all. Windows showed malfunctioned device. When I connected with another new USB cable, the SSD is good in performance. It took me an hour to find out the problem.

This 2TB Crucial External Hard Drive is very fast and that definitely works well when I’m working in the recording studio. It’s also compact and sturdy. Love it!

Use it for all more music production storage. Can get any better

Easy to use and has a tremendous amount of storage. I would buy another.

The Crucial X9 2 TB SSD Portable hard drive is a very reliable, inexpensive, easy to use and compact means of backing up your precious files, photos, videos and music from all of your primary devices. It is an essential accessory which can be used in an automatic or manual (batch) mode to very rapidly create backups of your data and preserve them against loss or corruption. It utilizes solid state NAND memory which is much faster and far more reliable than physical hard drive technology. Crucial is a line of DRAM and flash memory products produced by Micron Technology, Inc. Micron was founded in Boise, Idaho in 1978 as a four person semiconductor design company. In 1980 Micron built its first fabrication plant, producing its first product, a 64K DRAM in 1981. It became a public company in 1984 and that same year produced a 256K DRAM, followed by a 1 MB DRAM in 1987. Crucial was created in 1996 to sell memory upgrades to end-users. Later Micron acquired Texas Instruments’ memory business and Toshiba’s DRAM operations. In 2002 Micron created the first 1 GB DDR DRAM, then in 2004 the first 2 GB NAND flash memory product. Micron Technology continued to make acquisitions, including Lexar Media, and today has annual sales of $16 billion. Here are the key features of this great backup tool: • Crucial X9 2.0 Terabyte portable external solid state hard drive (SSD) (Model: CT2000X9SSD9) • USB 3.2 Gen 2 (10 GB/sec) interface and power source, USB 2.0 compatible • Up to 1,050 MB/sec data transfer rate • Utilizes Micron 176 level 3D QLC NAND • Endurance: 1,000+ write cycles • Drop-proof up to 7 feet • Highly resistant to shock, vibration and extreme temperatures • Music capacity: Approximately 11,000 albums (240,000 songs) at high quality compression • Video capacity: Approximately 240 hours of HD video • Matt black ABS plastic case • 9.5 inch USB-C to USB-C connection cable • Very Compact: 2.0 x 2.5 x 0.4 inches • Featherweight: 1.6 ounces (including cable) • Lanyard hole (no lanyard included) • Includes Acronis True Image software for backing up and cloning drive • Also includes one month trial of Mylio Photos for photo organizing and one month trial to Adobe Acrobat Pro software • Three year limited warranty The Crucial X9 is very tiny, much smaller than a conventional external drive (see photo comparison with a standard 2 TB drive next to the X9). The SSD is an attractive little package in matte black with glossy edges. But more importantly, it seems solid and should give good protection for the drive. Crucial states that the X9 drive can survive a 7 foot drop and is resistant to shock, vibration and temperature extremes. Most users really don’t understand how fragile a conventional hard drive can be. They consist of a set of magnetic platters rotating at high rate (usually 5400 RPM or higher) with a set of pickup arms moving across their surface to read the data and transfer it. While hard drives are somewhat shock resistant, a hard jolt can actually cause the arm to contact the platter surface and permanently damage the drive. That is why laptops frequently have hard drive failures – users casually bump them, drop them or otherwise abuse them. Solid State Drives (SSD) are immune to this kind of damage. Use of this Crucial external drive could not be easier. Just attach the included USB connection cord, plug it into a USB C port on your computer and look for a drive labeled “Crucial X9.” The connection cable provides the power for the drive. The included Acronis and trial software is on the SSD and there is a link to register the drive’s warranty with Crucial. I suggest that you copy all files to a folder on your PC. Then reformat the X9 to use the NTFS file system. This is a quick process and will enable you to store larger files on the SSD. While the Acronis backup software will do a nice job of backing up your hard drive, I suggest that you follow a simple manual procedure which is reliable and fool-proof. First, download a copy of the free Belarc Advisor software. It will create a detailed inventory of your programs and hardware, but most significantly, it will record the software license keys needed to reinstall some software (such as the Windows operating system and Microsoft Office.) Save this as a PDF with the date in the file name. Next, create a new folder on the Crucial X9, labeled with the name of your computer and the date. Find the “Users” folder in the C drive and drag the subfolders (Documents, Desktop, Pictures, Videos, Music, etc.) it over to that new folder on the SSD. That will copy all of your personal files and key hidden files (like the PST file used by Outlook to store emails, calendar and contacts.). Don’t bother copying your programs or the Windows files since if your PC fails, you will need to reinstall all of them. But the list of programs in the Belarc PDF will tell you what you need to reinstall. The more important files are your personal documents, photos, music, videos, etc. You might also make a practice of creating a copy of any of your downloaded software into a separate subfolder in your Users folder. That will make it easier to recover. Do the above procedure as often as you feel necessary. I suggest once every three months for each of your computers for all of your User files. Keep the two most recent backups and (if you wish) delete the older backups. But here is the most important piece of advice I can give: Don’t assume that your backup folder is safe on just one backup hard drive! Buy a second Crucial X9 and make a second backup of your precious files on it. If you are really paranoid (or just very safety conscious) store that second external hard drive in your safe deposit box or at a storage facility. That will protect it in the event of theft or fire destroying your PC and your on-site backup hard drive. How long does it take to back up all of your files? The Music folder on my primary computer is 42.191 GB and it took just 138 seconds to copy it to the Crucial X9. That was an average data transfer rate of about 305.7 MB/second. Keep in mind that data transfer rates will vary based upon your own computer’s processor, RAM and hard drive, but you can assume that it will take about 10 minutes in most cases and you can keep using your PC while the backup is proceeding. By the way, if you have an older PC which does not have USB-C ports and has only USB 2.0 ports, the backup process will still work, but it will take much longer (10X-20X) as long for the data transfer to take place. You will also need to use a USB-C to USB-A cable (which is not included with the Crucial X9, but readily available.) For comparison, I copied that same Music folder over to a standard 2GB external HDD, connected to a 3.2 USB Type A port. That port is about half as fast (10 GB/sec vs 20 GB/sec) as a USB Type C port. The copy process took 4,086 seconds – an average transfer rate of just 10.3 MB/second. The older style HDD took about 30 times as long as the Crucial X9! Are there any drawbacks to SSD technology? Theoretically, the NAND memory cells have a limited number of write/erase cycles. Each time the cell is erased to store new data an oxide layer necessary for operation is slightly eroded. Eventually the data in the cell cannot be changed. At that point the drive will still allow access to the stored data but it cannot be changed. For the type of memory used in the Crucial X9 the maximum number of write cycles is about 1,000. However, no user is likely to ever hit that number of write cycles in normal use. It would mean writing and erasing about 2,000 terabytes of data on the same Crucial X9. That would mean backing up your PC and replacing that backup about 5,000 times since a full backup would be about 400 GB of data. That would never happen! The Crucial X9 is very rugged – you can drop it, shake it, store it in a hot attic or an unheated garage – and it will still function perfectly. It is ideal for long-term storage of your precious data. Bottom line: Don’t hesitate; buy a pair of these Crucial X9 2.0 TB drives! It is a bargain at a price of about $50 per TB, is made by a premier semiconductor manufacturer, could not be easier to use and will ensure that you will always have a reliable copy of your irreplaceable photos, videos, documents and all of the other essential elements of your personal history. But after you buy it, make sure that you use it every few months to create a full backup of your files. Someday you will be very grateful that you did so!

Quick Overview ================================= You'll never have enough storage. On top of that, the faster the storage is, the better! The Crucial X9 is a tiny portable (it even has a lanyard hole!) SSD that's flexible enough to use for home or gaming. Overall build ================================= Opening the box, you'll be surprised at how small the Crucial X9 is - it's tiny! It takes up less than half of the box, measuring just under 2" x 3" (specifically 65mm x 50mm). It also comes with a tiny USB-C cable and Quick Start guide that just directs you to Crucial's website. Since this is a plug-and-play device, I wouldn't worry about that too much. It's plastic, but it's a hard, firm plastic with no flex or creaking to it. It's actually drop-rated to survive drops up to 7.5 feet! It can handle extreme temperature, shock and vibration, but it's not IP-rated for water or dust ingress. Still, I think it's a pretty sturdy device as long as you're not taking it off-road or camping. It has a 3-year warranty and I'm happy to say in the rare cases that I've had issues with Crucial devices (SD cards, memory), I've been taken care of. It's listed as compatible with every OS from Windows to Mac to Android/iOS and will work with gaming consoles like an Xbox or Playstation. Not only that, since it's a hard drive, it was detected by my Steam Deck as well. Note - there are a few steps to get it working under SteamOS/Linux, but that's not in-scope for this review, though it's definitely a way to add more storage to your Deck! The most interesting software that's included is Acronis which can be used to back up your PC and migrate the data to another one. I've used Acronis quite a bit as a PC builder and it's always worked reliably for me. Performance ================================= Not all SSDs are the same (SATA, NVMe) and neither are the connectors (USB-A, USB-C) with even more specific variants under each type! It can get confusing, but if you have a new or fairly recent device with a native USB-C port you should get the rated speeds. I've attached a screenshot of my CrystalDiskMark performance and it's nearly the same as Crucial's factory performance ratings. This is great to see since many of the factory or lab tests are under "perfect" conditions that aren't really applicable to the real world. I got the fastest speeds on my most performant device, my Asus Strix 18. I have another Dell desktop with a USB-C port (that's obviously not 3.2) and was getting about half the speeds. Still, this is a super-fast drive if you don't need the ultimate performance from their top-of-the-line X10 Pro. As I've been creating more videos, I have to move large files around quite a bit and some testing with this drive was impressive: ------------------------------------------- 2.77 GB in less than 5 seconds 3.77 GB in 6.5 seconds 5.78 GB in less than 10 seconds This was all hand-timed using my phone's stopwatch feature, but you get the idea. My "deep storage" consists of a larger set of SATA HDDs and copying those same files can be 3-4x longer! Games are getting larger and larger, from 10s of GB to 100s of GB for some of the top AAA games, so more storage is always welcome! With the older USB-A/USB 3.x implementation, you were limited to a maximum of 5 Gbps, but real world could be much slower so it wouldn't be ideal for gaming. Now, with up to 10 Gbps (or even 20 Gbps at USB3.2 Gen 2x2) like in this Crucial X9, gaming is no problem. Adding this drive to my Steam Library on my current gaming PC (Asus Strix 18) was a no-brainer and there was no perceptible difference playing a game that was installed on my internal NVMe SSD or on the Crucial X9. That was a fun way to test the drive! If you're running out of space in your gaming rig and don't have additional internal NVMe/M.2 slots, this drive is definitely an easy way to upgrade your storage without having to open up your PC. Conclusion ================================= Fast storage, that's tiny, portable and fairly rugged at a great price from a company that's known for reliability and performance. I'm not sure what else you could ask for outside of hardware encryption or slightly faster speed offered by the X10 Pro. For gaming, storage of your photos, videos, and other general use-cases, I'd say you can't go wrong with this Crucial X9 portable SSD.

I am very computer savvy -- just wanted to make that clear before someone comments that I don't know what I am doing or talking about. I know that the performance of this drive is dependent on the quality of the cable, the speed of the port the cable is connected to, and the speed of the host drive where the data is coming from. The drive is advertised as having speeds up to 1,050 megabytes a second. When plugged in with the original USB-C cable, and transferring files to a M1 Pro MBP, I should not be getting bursts of 300 megabytes of second, with intermittent slowdowns that average 60 megabytes a second. At best when this drive was operating at the fastest speeds, it still fell short by roughly 800 megabytes a second. Additionally, when hooked up to my PC on USB-C and transferring files to a SSD, it's just a slow. To put it into comparison, my external conventional hard drive transferred the needed files faster overall. The connection stayed a solid 150 megabytes a second, and did not sputter out like the X9 did -- with dips to abysmal transfer speeds. Not going to bother exchanging it for another one just to find out it performs just as bad. TLDR: Brand new day old X9 has terrible read/write speeds, old conventional HDD beats it out over long transfers. Returning.
