Vansuny 64GB USB Flash Drive
Score: 58/100
KOOTION Retractable 128GB
Score: 46/100Rankings
The Vansuny 64 GB USB 3.0 drive combines a rugged all-metal body with waterproof, dust-proof and shock-proof ratings, making it ideal for harsh environments. Real-world transfer speeds fall short of the advertised figures, and the lack of an LED may be a minor inconvenience.
The KOOTION 128 GB Retractable USB 3.0 flash drive combines a cap-less retractable slider with decent read performance and broad device compatibility. It is an affordable option for students and casual users, though write speeds and actual usable capacity are modest.
