Sony AIT-3 Tape Drive Specifications

The following table summarizes the specifications for the Sony SDX-700C AIT drive.

Parameter

Specification

 

 

 

 

Ambient operating temperaturea

+40°F to +104°F

(+5°C to +40°C)

Storage temperature

-40°F to +158°F

(-40°C to +70°C)

 

 

Operating humidity

20% to 80% non-condensing

 

 

MTBF

400,000 hours @ 100% duty cycle

 

 

 

Average access time

< 27 seconds

 

 

 

 

Uncorrectable error rate

< 1 x 10-17bits

 

Sustained transfer rate b, c

12 Mbytes /second native

Burst transfer rate d

160 Mbytes/s Synchronous maximum

a.The upper limit applies to the drives themselves. The temperature limits for the Spectra 12000 library are given in Operating Environment Limits on page 165. Be sure there is adequate air flow around the library at all times.

b.This is a per drive value. Total sustained transfer rate for the library depends on the number of drives installed in the library.

c.The sustained transfer rate per drive can increase by an average of 2.6 times the specified value with compression. Compression thoughput and capacity depends on the type of data.

d.The actual burst data transfer rate is limited by the performance of the SCSI host bus adapter, the SCSI bus interface controller, and the buffer control hardware of the drive.
