The Crucial X9 is one of the most portable SSDs I can remember, it can easily fit in your jeans or jacket pocket and not feel large or bulky, with the usb-c cable the only thing that breaks the stealth aesthetic. Totally self powered over usb-c with a TON of storage for the size at 2TB in the palm of your hands. I was getting the advertised speeds at 1020/961 MB/s read/writes which is USB 3.2 Gen2 2x1 speeds (10Gbps) max. Your speeds will vary depending on chipset and platform capabilities, this was on Z690 with a 12900K.

Great price, fast shipping, works as intended.

fast durable looks cool

Portable, simple setup, useful dual connector design

Data transfer speeds are amazing! Especially the storage and protection solid case 👍👍👍

I got a great deal on this because it was on sale. I needed big portable storage. I had another 2TB thumb drive, but when my laptop fell it nearly broke off the plug. I'd been using an extender with multiple sockets to avoid that, but this was way better. The yellow loop comes off, and then one end goes in the drive and the other in the USB-C port. Connections are firm. It feels extremely durable--metal casing and no projecting or moving parts to break or wear out. I feel like I could drive over it and it would still be OK. I can't speak technically about speed, but it's plenty fast for me. The little light at the end is always flashing colors while it's plugged in!

So I got the drive, hooked it up to my Thunderbolt on my motherboard, and I transferred some files to my C drive, and I got a two-gig transfer speed. The Reading speed is great


Small and rugged

Arrived formatted exFat, GPT from Crucial. A few preinstalled offers included links to, Acronis backup software, Mylio Photo Organizer and the Crucial support webpage. The first thing I did was use software to repartition the drive then format to NTFS. I will mention after running synthetic benchmarks formatted NTFS then reformatted back to exFat produced little difference in benchmarks speed-wise. I used Crystal DiskMark9 to check speed. I have a Thunderbolt PCIE card installed and anticipated a jump in Read/Write speeds when using the Thunderbolt option. To my surprise, there was little difference in speed from the USB-C than when tested while connected to the Thunderbolt adapter. When connected with USB-C Read/Write bench speeds of 1041/1005 MB/s were reached. Testing speed connected to the PCIE Thunderbolt adapted showed R/W 1043/1023 MB/s. The synthetic speed tests were well below the advertised 2100 MB/s. I wasnt disappointed with the speeds, but I did expect my tests to be closer to the advertised speeds. And Im not sure why my unit didnt test closer to the 2100 MB/s. The advertised speeds could have been reached using a different software, not sure why my results showed lower R/W speeds. I happened to have a portable 1GB hard drive from around the 2004 era. The speeds hardly compare to the Crucial X10, but its amusing to see the difference in the size of the units (see picture). This Crucial X10 is nothing short of extraordinarily fast for a portable USB drive. I will definitely be using this drive next time I copy my music and music video files. Large enough to copy my main PCs entire storage drive. The cutting-edge speeds will be a real time-saver.

tiny, fast

Really small size Comes with 2 cables with different connectors Easy setup



I got this drive for my iphone and my pc backup. Very, very fast and easy to do.

Great price and item! Worked just as advertised got more space on my X/S Now I don't have to delete anything or move games from one standard 4tb hard drive that can't play the games just stores them.


Plug-n-play, no separate power brick required. Very fast with USB-C port. Amazingly compact for a drive of 4 TB size. Well made and good looking case design. Packaging is very sturdy.

This product does work as advertised but I needed to buy a Thunderbolt 4 cable and plug it into the only USB-C Gen 4 2x2 port on my PC. On the front USB-C port is a Gen 3 port, I "only" get 1000MB/s read instead.

Been using the T7 Shield for about a year. Replaced one of my high-capacity 7,200-rpm hard drives that died after years of service. Bought the 2TB size / plenty of space for my needs 256-bit AES encryption is at the hardware level so the data is protected and the drive is fast USB powered, no external power supply USB-A and USB -C cords included Samsung Magician software is good for password access and providing stats on the performance and health of the drive Take it with me everywhere, small and light, rugged with non-slip coating Mirror it to other external drives for data backup in case it gets lost or stolen
