IBM Half-High LTO Generation 3 SAS Tape Drive

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-inch 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).

IBM Half-High LTO Generation 4 SAS Tape Drive

The IBM Half High LTO Generation 4 SAS Tape Drive is the fourth-generation Linear Tape-Open (LTO) offering introducing larger storage capacities, increased performance, and advanced security features to effectively meet the demanding backup, archival and regulatory compliance requirements of your System
x environments.

The IBM Half High LTO Generation 4 SAS Tape Drive is an excellent tape storage solution for businesses requiring backup or low-cost, real-time archiving of their data within a small window of time. This fourth generation drive provides up to twice the storage capacity, up to 1.6 TB with 2:1 compression, and
provides up to a 50% performance increase, up to 240 MBps (864 GB/hr) with 2:1 compression, over the preceding LTO 3 half height technology. This enterprise data protection offering is available in a 5.25-inch half-height internal form factor for integration into IBM System x tower servers and external IBM 1U
rack-mount enclosures or a half-height external unit for stand-alone table top or rack shelf applications.
