Score: 57/100Rankings
The SanDisk Extreme Portable SSD 1TB delivers flagship-class NVMe speeds, IP65 ruggedness and 3 m drop protection in a feather-light package, backed by a generous five-year warranty. While performance is excellent, some users have encountered early failures and a problematic USB-A adapter.
The KOOTION 1TB Portable SSD offers flagship-class read speeds and a rugged aluminum-plus-silicone build in an ultra-light package. Its performance hinges on having a USB 3.2 Gen 2x2 host, and it lacks built-in security features.

Professional editors view the Kootion 1TB SSD as a compelling budget option that delivers headline-grabbing 2000 MB/s read speeds, but they caution that those numbers are only reachable with a USB 3.2 Gen 2x2 host. They praise the inclusion of both USB-C and USB-A cables, the rugged aluminum-plus-silicone construction, and the use of A+ grade NAND, while noting the lack of publicly disclosed endurance data and built-in security features.
Everyday users love the drive's tiny footprint, lightning-fast transfers of large media files, and its drop-proof build. Common praise centers on plug-and-play ease, the handy keyring hole, and the fact that it works straight out of the box. Recurring complaints focus on limited speeds on older computers, a silicone sleeve that gets sticky, and confusion between the X6 and X1MAX models.
