Crucial X9 4TB Portable SSD with USB-A Adapter - Up to 1050MB/s - PC and Mac, with Mylio Photos+ - USB-C 3.2 External Solid State Drive - CT4000X9SSD902

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.

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

I purchased this Crucial 1TB SSD to replace a Sandisk SSD that suddenly failed. The Crucial SSD is a smaller physical size than the Sandisk unit, and has the same rated Read/Write speeds. I use this SSD to back up my MacBook using Time Machine, and it works very well. It comes with a short USB-C to USB-C cable. It also has holes to attach a lanyard, but it doesn't come with a lanyard.I purchased it because of Crucial's reputation for building reliable devices.

Great size and oustanding performance. One of the best option to backup.Crucial has a remarkable history as Memory provider and was a legacy fromMicron, ancient company that sold PCs back in the 90s. I would recommend thisCrucial X9 to anyone interested in backup and protect important documents anddata. Also the device have a nice design and was approved on several engnieeringtests. At this price it is a great choice.

You don't really get a sense for how small this is until you hold it in your hand. It's much smaller than the SanDisk SSD that has the weird loop at the top, and is also thinner than the SanDisk. Incredible feat of engineering.I'm using this for Time Machine purposes on a Mac. Runs cool, and with Time Machine, speed isn't of the essence. I went with an SSD because Time Machine requires APFS formatting, which doesn't work well these days with spinning HDs.On my Mac Mini Pro 2, it connects at 10gbps when plugged directly into the Mac, but intermittently disconnects. I ascribe this more to the Mac than to this product, as I've seen other people having similar issues with other drives.I have a CalDigit TS3+ Thunderbolt dock plugged into my Mac, and it has a 10gbps USB-C port. When I plug this SSD into that port, it only connects at 5gpbs for reasons unclear. Since I'm using this for Time Machine, the difference between 5gbps and 10gbps is negligible, so I haven't investigated this further. No intermittent disconnects plugged into the dock though.The cable they give you is a short 6-inch USB-C cable, which works well enough.This is overall a good "tweener" SSD. There are faster SSDs (2100MB/s), but they're significantly more expensive, particularly for 4TB. For this speed (1050MB/s) and capacity (4TB), Crucial is the least expensive "brand I've heard of" that I would consider -- it's less expensive than SanDisk, Western Digital, or Samsung. Recommended.
