2.Specification
SONY AIT-5 drive SDX-1100V series Ver.1.0 2-7
2.3.2. Data transfer Rate 2.3.2.1. Sustained Data Transfer Rate to and from the Tape
The sustained transfer rate to and from the tape is 24Mbyte per second with AIT-4 and AIT-5 cassette, 18Mbyte
per second with AIT-3Ex cassette, 16Mbyte per second with AIT-3 cassette. For this sustained rate to be achieved,
the drive must be streaming.
2.3.2.2. Burst Transfer Rate to and from the SCSI Bus
The SDX-1100V will transmit and receive data bursts to and from the SCSI bus at a maximum burst rate of
12Mbyte per second, using Ultra 160 asynchronous transfers and maximum of 160Mbyte per second, using
Ultra160 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 7 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-1100V. The time it
may take for retrying is not reflected here.
SDX3-100C (230 m) SDX3X-150C (246 m)
SDX4-200C (246 m) SDX5-400C (246 m)
Load Time 40 sec 14 sec 14 sec 14 sec
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-1100V. The time it may take for retrying is not reflected here.
SDX3-100C (230 m) SDX3X-150C (246 m)
SDX4-200C (246 m)
SDX5-400C (246 m)
Unload Time 24 sec 24 sec 24 sec 24 sec
2.3.6. Search Time 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-1100V. The time it may take for retrying is not reflected here.
SDX3-100C (230 m) SDX3X-150C (246 m)
SDX4-200C (246 m)
SDX5-400C (246 m)
Search Time 130 sec 130 sec 130 sec 130 sec
2.3.7. Rewind Time Rewind Time means the period from the beginning to the end of rewinding sequence. This value 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-1100V. The time it may take for retrying is not reflected here.
SDX3-100C (230 m) SDX3X-150C (246 m)
SDX4-200C (246 m)
SDX5-400C (246 m)
Rewind Time 105 sec 115 sec 115 sec 115 sec
