Score: 75/100Rankings
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.
TEAMGROUP's 512 GB S5 USB 3.2 Gen 1 thumb drive combines high read speeds, lightweight COB construction and water-, dust- and shock-resistance, making it a durable everyday storage option, though write performance details are lacking.
