Data Transfer Rate

Sustained Data Transfer Rate to and from the Tape

2.3.2.1.
The sustained transfer rate to and from the tape is 12 Mbyte per second with AIT-E Turbo, AIT-1 Turbo, AIT-2, and
AIT-2 Turbo cassette, 8 Mbyte per second with AIT-1 cassette. For this sustained rate to be achieved, the drive must
be streaming. There may be some dependency on the host for this to be achieved.
2.3.2.2.

Burst Transfer Rate to and from the SCSI Bus

The SDX-550V will transmit and receive data bursts to and from the SCSI bus at a maximum burst rate of 12 Mbyte
per second, using Ultra 160 asynchronous transfers and maximum of 160 Mbyte per second, using Ultra 160
synchronous transfers.
2.3.3.

Initialize Time

Initialize Time means the period from the time the drive is powered on to the time when the drive is ready and waiting
for a SCSI command such as INQUIRY or TEST UNIT READY. Initialize Time is less than 5 seconds.
The drive will respond with BUSY status until the completion of the Initialize Time. The Initialize Time does not
include the time necessary for drive diagnostics to complete and the drive to become ready for tape insertion.

Load Time

2.3.4.
Load Time means the period from the time when the operator inserts a cassette into the drive to the time when the
drive is ready. The data in the below table represents the average time for SDX-550V. The time it may take for
retrying is not reflected here.

Unload Time

2.3.5.
Unload Time means the period from the beginning of the unload sequence caused by Unload Command or Eject
button to the time when a cassette is ejected from the slot. Unload Time does not include Rewind time. The data in
the below table represents the average time for SDX-550V. The time it may take for retrying is not reflected here.
