Tape Drive Features
Fast Data Transfer Rate
Used for unattended backups or archiving, the tape drive allows the user to back
up a higher data capacity at a higher speed than earlier products. The tape
drive, when operating in a noncompressed mode, has a maximum transfer rate
of 5.0 MB/s. When operating in the compressed mode, the maximum transfer
rate is 10.0 MB/s.
High-Capacity
The tape drive accepts the DLTtape IV cartridge. When this cartridge is used the
amount of data stored on the tape can be up to 35.0 GB noncompressed or 70.0
GB compressed. The actual amount of this data stored in the compression
mode is dependent on the data type. Compression can be selected on the drive
front panel or from the host by using the SCSI MODE SELECT command.
The tape drive also accepts the DLTtape IIIxt cartridge. When this cartridge is
used the amount of data stored on the tape can be up to 15.0 GB
noncompressed or 30.0 GB compressed. The actual amount of data stored in
the compression mode is dependent on the data type. Compression can be
selected on the drive front panel or from the host by using the SCSI MODE
SELECT command.
The tape drive also accepts the DLTtape III cartridge. When this cartridge is
used the amount of data stored on the tape can be up to 10.0 GB
noncompressed or 20.0 GB compressed. The actual amount of data stored in
the compression mode is dependent on the data type. Compression can be
selected on the drive front panel or from the host by using the SCSI MODE
SELECT command.
Compaction
The compaction feature of the tape drive helps to store data efficiently. A
read/write data cache of up to 8.0 MB allows working space for the compaction,
enabling maximum use of available tape space.
Durable Media
The tape media can endure 500,000 passes and has a shelf life of 30 years,
which provides superior media durability and data reliability.
Compatibility
HP is committed to maintaining compatibility within the DLT family of tape drives.
The tape drive’s tape products are the third generation of the tape products
which can read and write all previous formats back to the DLT 260 drive, DLT
600 drive, DLT 2000 drive, DLT 2000xt drive and DLT 4000 drive.
