Lexar SL400
Score: 88/100Rankings

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.

The Samsung T9 Portable SSD 4TB delivers blazing-fast 2,000 MB/s read/write performance via USB 3.2 Gen 2x2, coupled with rugged drop and shock protection and AES-256 encryption. Its top speed requires a compatible host and the device lacks an IP rating, while the included cables are short. Best suited for power users handling large 4K/8K video files.

Products in the top-left offer the best value (high score, low price).

Professional reviewers commend the T9 4TB for delivering blazing-fast 2,000 MB/s transfers, robust 3 m drop protection, and enterprise-grade AES-256 encryption, while noting that its peak performance is gated by the need for USB 3.2 Gen 2x2 hosts and the lack of an IP rating for environmental protection.
Everyday users rave about the drive's pocket-sized portability and real-world speed gains for video editing and backups, but many express frustration when the device falls back to 1,000 MB/s on older computers and cite the short supplied cables and occasional heat during long writes as pain points.
