Professional reviewers commend the SSK SD500 1TB for its impressive benchmark numbers-exceeding 1 GB/s in both read and write under optimal USB 3.2 Gen 2x2 conditions-and its solid aluminum build with drop resistance. They also note its broad OS compatibility, UASP/TRIM support, and value-for-money pricing, while cautioning that sustained writes dip after the cache is exhausted and the unit runs hotter than some rivals during long transfers.
