Abstract
The IBM Half-high LTO Generation 3 SAS Tape Drive 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 in a 5.25-inch, half-high form factor.
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 120 MBps. The LTO Generation 3 delivers strong performance with data transfers up to 60 MBps in native mode (216 GB/hr) and up to 120 MBps in compressed mode (432 GB/hr).

Did you know?
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.
