Sony SDX-1100V/R manual Data transfer Rate, Initialize Time, Load Time, Unload Time, Search Time

2.Specification

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.

Search Time

SDX3-100C (230 m)	SDX3X-150C (246 m)	SDX4-200C (246 m)
130 sec	130 sec	130 sec

SDX5-400C (246 m)

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
