LTO Generation 6 tape drives feature hardware-based data encryption capabilities and support write once, read many (WORM) cartridges to help protect your data. With WORM cartridges you can store vital data in a non-erasable, non-rewritable format, while AES256 hardware encryption can securely store data to help ensure compliancy with data security, information disclosure, and privacy regulations for data at rest.This drive is compatible with the cartridges of its predecessor, the Half-High LTO Ultrium 5 Tape Drive. It can also read generation 4 cartridges.
