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 2. Performance characteristics
Performance Characteristics
Native data rate
Maximum sustained data rate (at maximum compression)
Burst data rate for Low Voltage Differential (LVD) SCSI drives
Nominal load-to-ready time
Nominal unload time
Average search time to first byte of data
Maximum rewind time
Note: All sustained data rates are dependent on the capabilities of the interconnect (for example, an UltraSCSI bus
is limited to less than 40 MB/sec).
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, SCSI bus capabilities, and system
or application software.
