A week? Were those drives running continuously? I've read
(in an O'Reilly book, at that...) that the different drive technologies
are designed for different duty cycles:
DAT 20%
DLT 100%
AIT 10% (!!!)
Given transfer rates of the following (compressed):
DDS-3 5 GB/h (according to last night's backup)
DLT 7000 36 GB/h (according to O'Reilly)
AIT 22 GB/h (according to O'Reilly)
this gives daily throughput of:
DDS-3 24 GB/day
DLT 7000 864 GB/day
AIT 52 GB/day
Draw your own conclusions...
