At disk creation I can select "SCSCI" or "Direct-IO.
Direct IO is faster, so obviously that's what has my preference
Question, how can I know "Direct-IO" works for the software that's going to use that disk?
I'll put a database on the RAMdisk. Does that usually work on a direct IO disk?
I guess, it's just "Try and see" but in general, does a database benefit from Direct IO? The speed increase on 4k acces is large.
