I can't find a good web page to refer you to, but here's a quick
summary of what's available.  Capacity and transfer rate are native; if
your data is 2:1 compressible, double both columns.

Drive   Capacity  Xfer rate
        (GB)      (MB/Sec)

DLT     40        6
sDLT    110-300   11-36
LTO     100       15
LTO2    200       30
AIT3    100       12
SAIT1   500       30
