X9 2TB Portable SSD, Up to 1050MB/s, USB 3.2 USB-C, External Solid State Drive, Compatible with Windows, Mac, & Android, Reliable Storage for Games, Files, & Backups, Black - CT2000X9SSD902

I love this SSD drive. I use it multiple times daily, and it works so well with my Windows 11 computers. I have used multiple backup drives that were HDD and would have to replace them within a short amount of time because of using them so frequently. I store all my family files on this SSD and use it as our external backup for receipts, passwords etc. This is the first SSD drive I’ve used, but so far, I can say I’m a convert and even though it’s definitely an investment upfront it has been worth it. I’ve had this drive for almost three months. It still works just as quickly as it did on day one, I’ve not had any data loss, it’s easy to hook up and remove from my computer, and it’s black and small enough to easily fit in a purse/bag or a suitcase if I needed to take it with me. Although looks weren’t as important to me. It’s also extremely quiet. In fact, to hear noise from the SSD drive I’ve had to put the drive right up next to my ear, and even then, I heard very little noise. I would highly recommend SSD and especially this Crucial one. I will purchase again if the one I have dies or if I need an additional one.

I’ve been using the Crucial X9 4TB Portable SSD for a few weeks now, and I’m seriously impressed. For those who want big storage without bulk, this is it. ⸻ What I love: • Compact & lightweight — It’s so small and thin, it easily fits in a jacket pocket or laptop bag without adding bulk. • Massive capacity — 4 TB gives me peace of mind. I can store video files, large photo libraries, backups, games, etc., without constantly juggling what to keep or delete. • Good speed — It delivers up to ~1050 MB/s (per Crucial) for sequential reads, which for me has meant fast transfers of large video files. (Of course, your speed depends on your USB-port, etc.)  • Durability — It has IP55 water/dust resistance and survives drops to about 7.5 ft / 2 metres (on carpet). That gives me confidence using it on the go.  • Compatibility — Works seamlessly with Windows, Mac, Android, etc. The USB-C interface + USB-A adapter makes it flexible for different devices.  ⸻ What to watch out for / minor drawbacks: • Speeds vary — It’s great when connected via a high-speed USB-C port, but if you use older or slower ports, you won’t get top performance. • Price — Naturally, a 4 TB SSD like this comes at a premium vs smaller drives or HDDs. If you don’t need all that space immediately, you might find smaller capacity options more cost-efficient. • Heat / throttling — I didn’t notice big issues yet, but as with many portable SSDs, heavy sustained transfers can warm it up. Just something I keep in mind. ⸻ Bottom line: If you’re after “big storage in a tiny package”, the Crucial X9 4TB hits the mark. Excellent for content creators, frequent travelers, or anyone who doesn’t want to worry about running out of space. Definitely worth the investment in my book.

Works great and feels much faster than my old drive. Easy to install and very reliable. Good quality from a trusted brand. Totally worth the money.

CrystalDiskMark reports max sequential read of 1067 MB/sec, and sequential write of 1039 MB / sec. Sustained transfers from NVMe to the drive through USB 3.2 Gen2 run about 650 MB/sec. CrystalDiskInfo reports operating temps while powered on and idle around 40-45C, even under a heavy load operating temps never hit 70C. Comes preformatted in exFAT, which ensures compatibility across different devices and OS environments (PC, Mac, Linux, Android, etc,) so if you aren't the most tech-savvy person, it will work well to plug and play right out of the box. This thing is unbelievably small, just a little bit bigger footprint than two USB sticks side by side, and has a smaller footprint than a credit card. Virtually no noise when in operation, because SSDs don't have any moving parts. The only drawback is that the housing is plastic, metal would have been nice for durability and to help with heat dissipation. If I were going to transport this drive frequently, I'd invest in a protective sleeve of some sort, just to prevent the possibility of the housing cracking if it was dropped on a hard surface, but for typical use it should hold up just fine. Any drive can and eventually will fail, and every drive model is going to have a certain amount of defective units, but I've written almost a TB of data to this drive, and so far, so good! I'll update this review if any problems become apparent, but thus far, this seems to be a quality SSD at a great price!

I bought this to replace an old USB 3.0 external drive. This drive is much nicer. It's less than half the size and so much faster! I would have liked something bigger than 2 TB, but the prices haven't come down quite enough yet. I thought the price of this drive was reasonable, and it's doing a good job for me. I am considering purchasing another one

Very very compact compared to the regular hard drive. Have owned it for little over a Month and it is reliable so far. Transfer Speed is also good.

Crucial is a known brand when it comes to memory upgrades. When I received this eternal drive, I was a bit disappointed -- it looked so small I thought it might just be an adapter or internal memory. But it’s the real deal: Compact and lightweight enough to dangle from a laptop by the USB cable. It might not be the fastest SSD, but its factors better than an HDD. It came preformatted in ExFAT, but I switched to NTFS to better suit my performance needs. At this price, it’s a bargain -- and I’m already wishing I’d gone for an additional 1 or 2TB.

Update: This thing is so bad I can't even transfer the data back to the original drive it was on... speed of 0, it's completely frozen. Has been like this at 3% and 0 transfer speed for over two hours now. Now I have to download it all again. nearly 500GB uncompressed... Why did it let me transfer the files to it so easily, but when I want to transfer them back it refuses and chokes and dies? This is so stupid. Thanks so much for the waste of time and money.. DO NOT BUY THIS. Well first off I got the adapter because I thought I needed it but never received it. Instead of shipping it together with the SSD they supposedly shipped the adapter a day before the Drive and despite saying it was delivered it wasn't, but that's a whole other thing and a waste of 10$. I ended up having a USB-C Port on my PC Tower that I didn't know was USB-C because nothing I own uses that. Why I bought this, I purchased this specifically to develop games/apps using Unity. My main drive is also a 1TB but it only allows access to 800GB and system files I can't remove are taking up a majority of the space with DCS taking up the rest. My second Drive is the drive that came with the PC and is only 250GB and has Steam and War Thunder on it. So you see why I needed another drive for Game Development. After being unable to use Unity on this SSD I thought I might as well transfer my DCS install over to it to free up the space for Unity on the main Drive. Yet for some really suspicious and weird reason it only freed up 300GB on my main Drive but took up over 530GB on this SSD. Really weird. It is soooooo slow. Any application I put on it seems to nearly kill it. When I try to access anything I put on it it completely freezes Windows Explorer for 1-5 minutes before finally doing what I asked it to do, or if it is taking longer than 5 minutes I just end up using Task Manager to end it. I first tried putting Unity on the SSD and it just absolutely refused to do anything with it. Really seemed like it had no idea what to do and just refused to install any Editor version, leaving errors for addons and the editor itself stuck on "installing" but never progressing. After force closing Unity Hub and trying to open it again the Drive just refused. It never opened. I then removed all that and put my DCS install on it to free up my main Disk Drive. That went fine and it even loads into the program incredibly fast, way faster than when it was on my main Drive. However when trying to actually play it first loads incredibly fast as usual but then about halfway through when it comes time to load the graphics it just completely chokes and I have to force close the program every time, so I have no idea how the Drive performs while in-flight.(Update) While writing out this review I had left a mission loading in the background instead of force closing the game after it froze. I was suddenly surprised after 10 minutes, yes literally 10 minutes, it actually loaded the mission. I just don't understand how it can do some things so incredibly fast, then just stop dead and freeze up with other things all while just loading a game. Once I started the mission everything was fine and smooth, nothing was wrong at all, then 30 seconds in it just froze again. 2 minutes later it started running and had no issues at all for the rest of the time I played that mission. I just really don't understand it. Really really disappointed in this SSD I did download the Crucial Executive just to make sure everything was good and see if I actually needed to do anything for the Drive to work properly, but that did nothing. Says the drive is fine. Although for some reason it tells me that the Drive has active partitions even when empty, which I also don't understand, so it won't even let me Format it. The Item Description even says it can hold "2 AAA game titles" but what's the point if it can't actually run them? Windows also recognizes my other two drives as Solid state but this Crucial drive as a regular Hard disc so what is up with that?
