Crucial X8 1TB
Score: 71/100
Buffalo External SSD USB-A 1TB
Score: 79/100Rankings
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.
The Crucial X8 1TB Portable SSD offers NVMe-class speeds and a rugged aluminum body at a competitive price, but lacks encryption and sees write performance dip after the cache is used.

Products in the top-left offer the best value (high score, low price).
Reviewers praise the X8 for delivering NVMe-class speeds, solid build, and thermal design, while noting the lack of hardware encryption and activity LED.
Users appreciate the fast transfers and build quality, but frequently mention the drop in sustained write speed and missing activity indicator.
“solid and stable performance after long-term use.”
“perhaps the fastest SSD with the most storage for the least price.”
“no longer available on the market.”
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.
