If you run applications that are highly dependent on tape-processing speed, take
advantage of the significant performance improvements provided by this tape
drive.
By using the built-in data-compression capability of the tape drive, greater data
rates than the native data transfer rate can be achieved. However, the actual
throughput is a function of many components, such as the host system processor,
disk data rate, block size, data compression ratio, SAS bus capabilities, and system
or application software.
The TS2250 uses the IBM LTO Ultrium 1500 GB Data Cartridge and is compatible
with the cartridges of its predecessor, the IBM TS2240 Tape Drive. The drive
performs the following functions:
v Reads and writes Generation 5 and Generation 4
v Only reads Generation 3 cartridges
