SanDisk Ultra Fit 512GB
Score: 89/100Rankings
The 512 GB ORICO USB-A flash drive delivers top-tier read speeds, solid write performance and rugged metal construction with IPX7 water resistance, targeting power users who need fast, reliable transfers. The detachable cap is a noted weak point.

The SanDisk Ultra Fit 512 GB USB 3.2 Gen 1 flash drive packs massive storage into an ultra-compact, low-profile design. It delivers excellent read performance and encryption, but its write speeds are notably slow and the plastic case offers limited ruggedness.
