Samsung FIT Plus 512GB
Score: 82/100Rankings
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.
The Samsung FIT Plus 512 GB USB-A flash drive delivers fast 400 MB/s read speeds in an ultra-compact metal shell with a keyring, offering five-way rugged protection and broad device compatibility. While its read performance is solid, write speeds can be inconsistent on older hosts and the lack of a USB-C connector limits use with modern ultrabooks.
