Parameter Specification
Power consumption Read/write: 34 watts typical
Idle: TBD
LTO-8 Drive
When connecting to a Fibre Channel network, LTO-8 Fibre Channel drives will
attempt to connect at 8Gb/second, but will auto-negotiate down to
4Gb/second, or 2Gb/second, depending on the requirements of the port to which the
drive is connected.
LTO-8 SAS drives attempt to connect at 6 Gb/second, but auto-negotiate down to 3
Gb/second or 1.5 Gb/second, depending on the requirements of the port to which the
drive is connected.

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.
c
A 1.5 Gb interface speed does not stream an LTO-8 drive at 360 MB/second.
