Professional reviewers applaud the X10's record-breaking compactness and rugged IP65/3 m drop build, noting its 2 GB/s peak speed potential and solid 10 Gbps performance on mainstream machines. However, they caution that full 20 Gbps throughput is rare, real-world sustained speeds are lower, and macOS/Thunderbolt systems are limited, making the advertised speed a conditional benefit.
Everyday users consistently praise the drive's tiny footprint and massive 8 TB capacity, highlighting its convenience for travel, backups, and multi-device workflows. Recurring complaints focus on speed throttling to around 1 GB/s on typical hosts, the missing USB-A adapter, and a sense that the product is overhyped when full 20 Gbps performance cannot be realized.

“the smallest 8TB drive imaginable”

“overhyped for non-20 Gbps hosts”
