SamData 64GB USB Flash Drive
Score: 63/100Rankings

SamData's 64 GB USB flash drives provide budget-friendly, rugged storage with basic USB 2.0 performance, making them suitable for everyday document and photo backups. Their slow speeds and lack of security features keep them from demanding professional use.

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.
