Drive Performance
If you run applications that are highly dependent on tape-processing
speed, take advantage of the significant performance improvements
provided by this tape drive.
Table 1 Performance
characteristics
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.
Cartridge Compatibility
The LTO-5 uses the Quantum LTO Ultrium 1500 GB Data Cartridge and is
compatible with the cartridges of its predecessor, the Quantum LTO-5
Tape Drive. The drive performs the following functions:
Performance Characteristics LTO-5 Tape Drive
Native data rate 140 MB/s (with Ultrium 5 media)
Maximum sustained data rate (at
maximum compression)
550 MB/s
Burst data rate 600MB/s
Nominal load-to-ready time 12 seconds
Nominal unload time 17 seconds
Average rewind time 75 seconds
Note:
All sustained data rates are dependent on the capabilities of
the interconnect.
