LTO8 tape profile - amtapetype

Just ran amtapetype against an LTO8 tape + HP MSL3040 (with SAS drives). Debian 11.

Some observations:
-compression on, expected
-length looks ok
-speed .. should I have expected more? Seemed a bit low I thought..
-no LEOM.. I don't know if it's the hardware or the Debian 11 kernel or both, though understand this is not essential
