Have
SATA drives implemented priorities on NCQ tags such that a tag of a lower or
higher tag number might get priority over the other tag? For example, if one command on the drive
uses tag 0, and another command uses tag 1, are they of equal priority? I realize that there are many factors
leading to which tag gets executed first, but right now I am only interested in
how the tag ID affects priority. A
somewhat related question: Have all
SATA NCQ drives implemented anti-starvation algorithms? Do they work well? I sometimes see situations where
commands are timing out even though other commands are currently serving data. |
