Buffalo SSD-SAO1.0U3B
Score: 78/100
Kootion KT-X1max-1TB
Score: 57/100Rankings
The Buffalo SSD-PUT 1TB packs a full-capacity SSD into a thumb-drive-sized body, offering decent USB 3.2 speeds after a firmware update and MIL-STD-810G shock resistance. Its ultra-small form factor and console support make it ideal for on-the-go gamers and professionals who value size over raw performance.
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 reviewers commend the SSD-PUT for its unprecedented miniaturization and solid performance for a thumb-drive size, but note the modest PCMark score, need for a firmware update, and lack of DRAM cache.
Everyday users love the pocket-size convenience and fast transfers after updating, while complaining about lower-than-advertised speeds out-of-the-box and concerns about the durability of the retractable plug.
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.
“Users love the ultra-portable design, often comparing it favorably to carrying a regular flash drive.”
“I keep it on my backpack! ... It is small, but stores my big files!!”
