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
LTO-6 Drive
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.
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
c. A 1 Gb interface speed will not stream an LTO-6 drive at 160 MB/second.
LTO-5 Drive
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.
