Data transfer Rate
2.3.2.
2.3.2.1.
Sustained Data Transfer Rate to and From the Tape
The sustained transfer rate to and from the tape is 6Mbyte per second with AIT-E Turbo and AIT-1 Turbo cassette ,
4Mbyte 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.
Burst Transfer Rate to and From the SCSI Bus
2.3.2.2.
The SDX-450V will transmit and receive data bursts to and from the SCSI bus at a maximum burst rate of 12 Mbyte
per second, using WIDE SCSI asynchronous transfers and 40 Mbyte per second, using WIDE SCSI synchronous
transfers.
Initialize Time
2.3.3.
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.
2.3.4.
Load Time
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-450V. The time it may take for
retrying is not reflected here.

2.3.5.
Unload Time
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-450V. The time it may take for retrying is not reflected here.

Search Time
2.3.6.
Search Time means the period for the drive to find the position that is required by a command. This time also
depends on the tape length and the position of the head along the tape. The data in the below table represents the
average time for SDX-450V. The time it may take for retrying is not reflected here.
