WORM (Write-Once,
Read-Many) Drive
and Media Support
Critical to the success of data retention policies in highly regulated environments is the ability to store and
manage data in an unalterable state. Following stringent guidelines set forth by regulatory agencies such
as the SEC and HIPPA, IT organizations must now integrate new solutions and policies that can verify the
integrity of stored data for periods that can extend well beyond seven years.
The LTO-6 Ultrium 6650, LTO-5 Ultrium 3280 and LTO-4 Ultrium 1840 tape drives feature the ability to
archive and store data in a non-rewriteable format that meets the most stringent regulatory guidelines.
Using a combination of integrated fail-safe features in the drive firmware, cartridge memory, and tape
formatting, the tape drives can archive large amounts of data for periods of up to 30 years in a secure,
untampered state. Since all LTO-6 Ultrium 6650, LTO-5 Ultrium 3280 and LTO-4 Ultrium 1840 tape drives
include support for both rewritable and WORM media, IT organizations can now easily integrate a secure,
long-term archiving solution into their current data protection strategy. As compared to other
technologies that feature support for WORM storage, the tape drives offer the advantages of:
A single drive to support all backup and archiving needs
Two distinctive tape cartridges to easily distinguish and manage both rewriteable and WORM data
cartridges
A specially designed WORM data cartridge with multiple integrated fail-safe features to prevent
accidental or intentional overwriting of data
High-capacity, low-cost HP WORM media that can store up to 3TB (2:1 compression) of data on a
single data cartridge. (HP LTO-6 Ultrium 6650 has 2.5:1 compression)
Support from many backup and archiving software vendors, providing the most comprehensive and
mainstream support in the industry
The LTO open standard that offers greater choice and compatibility across all third- and fourth-
generation Ultrium products
NOTE:
While all LTO-6 Ultrium 6650, HP LTO-5 Ultrium 3280 and LTO-4 Ultrium 1840tape drives support
LTO Ultrium WORM media, some third- and fourth-generation LTO Ultrium tape drives from other
manufacturers may not include read and write support for LTO Ultrium WORM media. For non-HP third-
and fourth-generation LTO Ultrium tape drives, please check the manufacturers' specifications to ensure
this support is provided if you are using your WORM media. If WORM support is not provided, the drive will
eject the WORM tape cartridge immediately upon insertion into to the tape drive.
