Buffalo External SSD USB-A 1TB
Score: 79/100
UGREEN 1TB SSD
Score: 52/100Rankings
Buffalo's 1 TB SSD-PUT is a thumb-drive-sized external SSD that delivers solid 600 MB/s read performance in a rugged, MIL-STD-810G package, though it needs a firmware update and uses an adapter for USB-C connectivity.
UGREEN's 1 TB Portable SSD delivers industry-leading 2,000 MB/s throughput with a dual-cooling aluminum chassis, but its heavier weight and lack of rugged ratings make it less suited for harsh environments.

Professional reviewers praise the SSD-PUT for its miniaturization, solid-state performance in a thumb-drive form factor, and rugged build, but note its modest PCMark score and the need for a firmware update, positioning it as a portable alternative rather than a high-end external SSD.
Everyday users love the tiny size, speed for file transfers, and durability, especially for gaming consoles and travel, while recurring frustrations focus on the required firmware update and the easily misplaced USB-C adapter.
“So small and fast!”
“Works perfectly with PS5”
“Durable and reliable”
Professional reviewers praise the Ugreen 1TB Portable SSD for its industry-leading 2,000 MB/s throughput, effective dual-cooling design that avoids throttling, and advanced error-correction features, positioning it as a premium alternative to the Samsung T7 Shield and similar high-speed SSDs.
Everyday users consistently commend the drive's lightning-fast transfers, pocket-size form factor, and plug-and-play experience across PCs, consoles and iPhones, while noting the need for a USB 3.2 Gen 2x2 host to unlock full speed and the absence of a transport case.
