The IBM Half High LTO Generation 3 SAS Tape Drive is the third-generation Linear Tape-Open (LTO) 

offering that delivers enterprise class capacity at an entry-level LTO Generation 3 price point. The drive 
offers an attractively priced entry offering into LTO technology for mid- to high-end System x servers 
requiring high-capacity, high-performance, and high-reliability tape solutions. These compact, half-high 
5.25” internal and external form factor offerings leverage IBM copper-based technology to enable 
low-power, low-temperature integration into IBM System x tower servers, external IBM 1U rack-mount 
enclosures or for the external unit to be used as a standalone table top or shelf unit.

Using its onboard hardware data compression feature and assuming a 2:1 compression ratio, this drive 

can store up to 800 GB compressed per cartridge at a backup rate of up to 160 MBps. The LTO 
Generation 3 delivers strong performance with data transfers up to 80 MBps in native mode (288 GB/hr) 
and up to 160 MBps in compressed mode (576 GB/hr).

The IBM Half-high LTO Generation 3 SAS Tape Drive is also designed to work with write once read many 

(WORM) cartridges to store data in a non-erasable, non-rewritable format. This can help support the 
long-term retention of reference data and meet the requirements of many regulatory bodies worldwide. 
The 400 GB WORM cartridge includes advanced security features that are designed to prevent the 
alteration or deletion of stored data, and is identified by its unique two-tone color.
