Tape drives
The Ultrium tape drive is a high performance streaming tape drive that uses LTO technology. The EML
E-Series uses the Ultrium 460 (LTO 2) and Ultrium 960 (LTO 3) tape drives, which are backwards
compatible with LTO 1 technology.
The Ultrium 960 includes support for both rewriteable and Write-Once, Read-Many (WORM) data
cartridges. WORM data cartridges provide an enhanced level of data security against alteration of data
on the tape cartridge because you cannot erase or overwrite data on the cartridge. To check whether
your backup or archive software applications supports WORM cartridges, see the following web site:
http://www.hp.com/go/connect .
For optimum performance, always use a data cartridge that matches the specification of your tape drive.
Table 2 shows drive compatibility and tape capacity. Other comparisons between the Ultrium 460 and
960 tape drives can be found in Table 28 on page 104.
Data cartridges and cleaning cartridges are specifically formatted for use with Ultrium drives. To order
Ultrium media, see ” Ordering HP tape cartridges and bar code label packs ” on page 123.
