Backwards Compatibility
HP DAT tape drives are backward read-write compatible with two previous generations, thus:
DAT 160 also reads and writes DAT 72 and DDS-4
DAT 72 also reads and writes DDS-4 and DDS-3
DAT 40 also reads and writes DDS-3 and DDS-2
Proven Reliability
HP DAT drives have proven to be exceptionally reliable. The drives have demonstrated exceptional
performance with customers over many years and across different generations and this has under pinned
their popularity.
The drives are designed with reliability in mind and with the security of customer's data as a priority.
Hardware reliability is typically measured as MTBF (Mean Time Between Failures) associated with duty
cycles which suggests the amount the drive is typically used e.g. 100% duty cycle means the drive is used
for 24 hours per day. As a result of field data, the specification for HP DDS products is stated as
125,000 hours at 100% duty cycle, or 1 million hours at a more typical 12% duty cycle (drive used on
average for 3 hours per day).
Unlike other manufactures DAT drives, this specification is not generated in the laboratory with limited
numbers of prototype drives and assumptions on customer use; it is generated from real customer data
for the products concerned.
