Crucial X10 8TB
Score: 89/100Rankings
The Crucial X10 8TB Portable SSD offers massive 8 TB storage in an ultra-compact, IP65-rated chassis with peak speeds up to 2.1 GB/s. Its performance is limited on typical hosts that lack 20 Gbps USB-C, and it does not include a USB-A adapter. Ideal for creators and travelers needing high capacity on the go.
The Lexar SL400 is a 2 TB portable SSD with an integrated 4-port USB-C hub, delivering up to 1050 MB/s read speeds. Its trade-off is a modest 1-year warranty and a relatively thick chassis for an SSD. Ideal for content creators needing fast, rugged, hub-enabled storage on the go.

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.

“overhyped for non-20 Gbps hosts”
