Are similar settings required for best performance of LTO-6 drives too?
Do you experience bad performance or is the speed not as expected? If no, just stick to the defaults. Otherwise ask the vendor or give more details about your LTO-6 drive.
Where do we know the values from?
Well, best would be to ask your hardware vendor or check on the manufacturer site and manual for your drive. Lastly you could just trail-n-error, if you experience bad performance.
What are the default settings, if no values are passed?
Look through dmesg
and use modinfo st
to reveal the possible values and defaults. You also could look at /sys/module/st/parameters/*
to see the current settings. Might be that this is not available.
