2.3.1.
Data Capacity
The SDX-560V includes a data compression capability. When data compression is enabled the drive capacity can
increase from 2 times to 3 times. The efficiency of the data compression depends on the actual data that is being
compressed and cannot be predicted precisely prior to compression.

Data transfer Rate
2.3.2.1. Sustained Data Transfer Rate to and from Tape
The sustained transfer rate to and from the tape is 12 Mbyte per second with AIT-E Turbo, AIT-1 Turbo, AIT-2, AIT-2
Turbo cassette. The sustained transfer rate to and from the tape is 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 and
application softwares for this to be achieved.
2.3.2.2.
Burst Transfer Rate to and from the IDE Bus
The SDX-560V will transmit and receive data bursts to and from the IDE bus at a maximum burst rate of 100 Mbyte
per second, using Ultra DMA (mode 5) transfer.
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 ATA/ATAPI 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.
