purchased the IRIX LTO3 Asynchronous Personality Daemon license, as this LTO 3 drive has functioned flawlessly since I traded in the Quantum drive for the HP (and edited the SCSI file).
Well, it's working fine, but it's SLOW. This takes about 36 hours to write a 400GB tape. This same tape extracts in about 6 hours.
I understand this would run substantially faster if I bought the APD package, but would I really get TEN TIMEs the performance if I had the $2500 APD license?
