Score: 78/100Rankings
Lexar's D40E 256 GB drive combines a dual-connector swivel metal housing with 256-bit AES encryption and strong sequential read performance. Write speeds can be inconsistent and the bulkier design reduces pocket-friendliness. Suited for photographers and videographers who value security and durability.
The Thkailar 512 GB USB flash drive offers a versatile dual-port design and a robust aluminum alloy body, delivering fast read speeds up to 120 MB/s. Its write performance is modest and it lacks built-in encryption, which may concern security-focused users. Ideal for business travelers needing cross-platform compatibility.
