Data Capacity

2.3.1.
The SDX-470V 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.
2.3.2.1.

Sustained Data Transfer Rate to and from Tape

The sustained transfer rate to and from the tape is 6 Mbyte per second with AIT-E Turbo and AIT-1 Turbo cassette.
4 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 Serial ATA

The SDX-470V will transmit and receive data bursts to and from the Serial ATA at a maximum burst rate of 150
Mbyte per second.

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 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.

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-470V. The time it may take for
retrying is not reflected here.
