Sony AIT-3 Tape Drive Specifications
The following table summarizes the specifications for the Sony SDX-700C
AIT drive.
Parameter Specification
Ambient operating temperature
a
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.
+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
-17
bits
Sustained transfer rate
b, c
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.
12 Mbytes /second native
Burst transfer rate d
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.
160 Mbytes/s Synchronous maximum
