Capability to write and read Travan TR-5 (QIC-3220-MC) media, as well as read
TR-4 media conforming to the QIC-3095 standard
•
QIC-3220-MC tape format compliance for compatibility and information
interchange
•
Typical uncompressed capacities of 10 gigabytes on 740 foot TR-5 media
•
Typical compressed capacities of 20 gigabytes on 740 foot TR-5 media
•
Transfer rate optimized with FastSense—automatic selection of fastest
supportable data transfer rate (1,000, 733, or 489 Kbyte/sec)
•
ATAPI interface that supports DMA and PIO modes 0, 1, or 2 with 512 Kbytes
on-drive data buffer to facilitate the most efficient use of the host computer and
tape drive.
•
Uncorrectable error rate of less than 1 in 10
15
bits
