Our take on the LEXAR SL400 1TB Go Portable SSD Black

The Lexar SL400 is a pocket-sized external SSD with 1TB of storage and a USB 3.2 Gen 2 interface rated at up to 1,050 MB/s read and 1,000 MB/s write. It weighs about half an ounce and is slim enough to slip into a pocket, and it connects over USB-C. It suits people moving large files between laptops, cameras and consoles, or backing up a machine. Against premium rivals like the Samsung T7 or SanDisk Extreme it gives similar sequential speeds and a lighter body, but it lacks the rugged ratings and hardware encryption some of those carry.
