LTO-7 Drive
When connecting to a Fibre Channel network, LTO-7 Fibre Channel drives attempt to
connect at 8Gb/second, but 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-7 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.

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.
