Corsair

Corsair EX100U 2TB

8.5/10

A 2TB Gen 2x2 portable SSD in the same aluminum-and-rubber body as the 1TB. Write speed drops slightly to 1800 MB/s on the 2TB variant — a real-world trade-off for the larger NAND die. Still above 2GB/s on long transfers as long as the host is Gen 2x2.

The X8 is Crucial's older-gen premium aluminum portable — superseded in retail by the X9 Pro but often available steeply discounted. Same 1050/1000 MB/s speeds, same form factor, same aluminum body. A solid budget pick when sale-priced under the X9 Pro.
