### ⭐⭐⭐⭐⭐ Small but powerful SSD that’s worth every penny
*by I***O on December 7, 2024*

The Crucial X9 Pro 2TB Portable SSD turned out to be an excellent choice for work and data storage. Its compact size — slightly larger than a credit card — makes it incredibly convenient for everyday use. This SSD not only takes up minimal space but also offers reliability with its IP55 dust and water resistance.The data transfer speed is impressive: I tested it using CrystalDiskMark, and it showed up to 1050 MB/s for reading and around 900 MB/s for writing, which is almost in line with the advertised specs. This greatly speeds up working with large files like videos and photos.The device’s sturdy rubberized casing adds confidence when traveling or using it in challenging conditions. However, the included cable is short, and you need a certified USB 3.2 Gen2 cable to achieve maximum speeds.Overall, this device is perfect for backup, storage, and data transfer. Small drawbacks like the short cable do not overshadow its overall performance. I highly recommend the Crucial X9 Pro to anyone looking for a portable and fast SSD

### ⭐⭐⭐⭐⭐ Great Value, Solid Performance — Just Watch Your Cables
*by M***. on July 15, 2025*

I’ve been using the Crucial X9 2TB Portable SSD for over a year now, mainly for backing up my photo library, and it’s been a dependable and high-performing drive.✔️ Build & Design:The drive is compact and sturdy, great for portability. The only downside is the included USB-C cable — it’s short. Not a big deal on a laptop, but it’s a bit inconvenient when plugging into the back of a desktop tower.✔️ Speed & Performance:I did not use the stock cables initially because its quite short. Upon testing I wasn’t getting the advertised read/write speeds. When I used the stock cable I got the advertised speeds for sequential writes/reads. Thus, I realized I was using third-party cables that weren’t USB 3.0. If you need longer cables, take this into consideration.✔️ Compatibility:Worked flawlessly on both my Windows 11 laptop and desktop — plug-and-play with no setup or reformatting needed.✔️ Heat:It gets slightly warm during large file transfers, but nothing alarming. I haven’t experienced any slowdowns or issues related to heat.✔️ Value for money:I bought this for $108, and for 2TB of portable SSD storage from a reliable brand like Crucial, that’s a steal. Zero problems after a year of use.

### ⭐⭐⭐⭐⭐ Compact Storage, Excellent Value
*by L***9 on March 4, 2025*

I can't believe how small this SSD drive is, barely larger than a book of matches. I use this to store and access approximately 11,000 songs stored in uncompressed .flac and .wav format. This SSD is attached via USB to a desktop computer on my home network, and I access it as a shared drive for my Sonos system. It is always visible on the network (unlike the SSD it replaced, which would disappear if not accessed for a while). I have had no issues with speed or file access, although I am certainly not stressing it for its reading and writing capabilities or speeds.The drive came formatted as exFat, which works with all versions of Windows and modern versions of macOS. It can be formatted as Fat32 or NTFS if necessary.I have used Crucial memory and storage drives for years and have always found them to have rock solid reliability, and the pricing is competitive with other less reliable or no name brands. They are a division of Micron, and were the first company to sell memory directly to the consumer. I cannot speak to the longevity as I have not had the drive very long, but based on my past experience with Crucial I am confident it will last.
