Kingston DataTraveler 100 G3 128GB
Score: 40/100
Samsung FIT Plus 512GB
Score: 82/100Rankings
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.
The Kingston DataTraveler 100 G3 128 GB offers solid read performance and a convenient sliding cap, but its write speeds and random performance are extremely low, making it best for occasional read-heavy tasks.
