Enhancements in fourth-generation drives

The 1640LTO supports the encryption of data. The 256-bit hardware encryption, which resides in the LTO-4 drive, offers customers security and higher protection of data at no additional cost without requiring additional equipment. Like LTO-3. LTO-4 drives will support Write Once Read Many (WORM) operation on LTO WORM cartridges, and prevent over-writes or erasing of previous written data, to comply with various data protection regulations.

Tandberg LTO-4 has a host of features for improved reliability, and for high performance in various host environments; Diagnostics routines test the functions of the drive and report the results to the operator. The tape drive uses the Statistical Analysis and Reporting System to assist in isolating failures between media and hardware. Adaptive tape threading through 8 independent sensor reading provide input to enhanced firmware to help protect against load failures. Graceful dynamic breaking will prevent abrupt stops during an unexpected power down and Digital Speed Matching (DSM) is designed to help improve throughput in environments where the host data rate is less than optimal.

The LTO-4 drive will be able to read and write LTO-3 media and read LTO-2 media.

Turnkey Solution

The Tandberg LTO-4 ships with Symantec's Backup Exec QuickStart software, embedded media management for intelligent diagnostics and tape alerts, and comes with 3 years warranty and support.
