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