Transfer Rates User Native = 6.0 MB/second
Compresseed = Up to 12.0
MB/second *
Error Rates Recoverable READ Error Rate =
1 in 106 bits read
Unrecoverable READ Error Rate = 1
in 1017 bits read **
Undetected READ Error Rate = 1 in
1027 bits read
Tracks 208 physical (52 quad logical tracks
on media); drive has 4 parallel
physical (1 logical) tracks written or
read simultaneously
Linear Bit Density 98,250 bpi per track
READ / WRITE Tape Speed 168 inches/second
Rewind Tape Speed 175 inches/second
Linear Search Tape Speed 175 inches/second
Average Rewind Time 60 seconds
* = Depending on data type and SCSI bus limitations/system configuration
** = An unrecoverable error is any READ error that cannot be recovered using the
drive’s internal error recovery algorithms or, if the drive indicates “Cleaning
Required”, by removing the data cartridge, performing a cleaning operation, and
attempting to re-read the data from the data cartridge.
