Score: 63/100Rankings
The SanDisk Ultra 256 GB USB-A flash drive offers solid capacity and fast read performance with built-in encryption, but its modest write speed and lack of an LED indicator limit its appeal for power users.
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.
