bAssumes a 2:1 compression ratio
Notes:
When compression is enabled, the tape drive can increase the sustained transfer rate of up to five times. Compression throughput and capacity ratios depend on the type of data.
The maximum burst data transfer rate is limited by the performance of the SCSI host bus adapter, the SCSI bus interface controller, and the tape drive’s buffer control hardware.
Reselection Phase Timeout
If the initiator fails to respond to a device reselection sequence, the tape drive times out after 250 msec. The tape drive continues to repeat the reselection process until it is reset or the initiator finally responds.
