Score: 40/100
Mecheer 8GB
Score: 35/100Rankings

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.

The MECHEER 8 GB 10-pack offers a rugged metal swivel design and low price, making it suitable for classrooms and bulk distribution. However its USB 2.0 interface and limited capacity restrict it to basic file sharing tasks.
