ADATA UE800 2TB
Score: 88/100Rankings
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 ADATA UE800 is a high-capacity (up to 2 TB, currently 1 TB) USB-C flash drive delivering near-maximum USB-C 3.2 Gen 2 speeds in a compact brushed-aluminum body. It excels in performance and portability but lacks ruggedness and built-in security features.
