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.

The Transcend JF790 512 GB USB flash drive offers high capacity and a convenient retractable design, making it suitable for everyday storage across many devices. While its speeds are adequate for typical documents and media, they fall short of premium drives, and it lacks encryption.
