LTO -6 Dri ve
When connecting to a Fibre Channel network, LTO-6 Fibre Channel drives
will attempt to connect at 8 Gb/second, but will auto-negotiate down to
4 Gb/second, 2 Gb/second, or 1 Gb/second, depending on the requirements
of the port to which the drive is connected.
LTO -5 Dri ve
When connecting to a Fibre Channel network, LTO-5 Fibre Channel drives
will attempt to connect at 8 Gb/second, but will auto-negotiate down to
4 Gb/second, 2 Gb/second, or 1 Gb/second, depending on the requirements
of the port to which the drive is connected.
Parameter Specification
Maximum sustained transfer rate
a, b
a. Assuming a 2.5:1 compression ratio. Compression throughput depends on the type of data.
b. This is a per-drive value. Total sustained transfer rate for the library depends on the number of drives
installed in the library.
160 MB/second, native
c
400 MB/second, compressed
c. A 1.5 Gb interface speed will not stream an LTO-6 drive at 160 MB/second.
Speed matching range 40 MB/second to 160 MB/second
Average space record time 77 seconds
Encryption capability AES 256-bit
WORM capability Yes
MTBF 250,000 hours at 100% duty cycle
Uncorrected error rate 1 x 10
–17
bits
Power consumption Read/write: 28 watts typical
Idle: 8 watts
