Netac U505 128GB
Score: 66/100Rankings

The Netac 128 GB USB-3.0 flash drive offers good read performance and a protective swivel cap at a low price, making it suitable for casual users. However, its modest write speed, lack of encryption, and reported reliability issues limit its appeal for power users.

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.
