Partitioning a raid array

[Veedo]

does partitioning a raid0 array have much affect on performance?

I would imagine that it would decrease the number of random reads and writes.

Not really, but why do you have raid0 at all? As many others have remarked, it's not much use unless you're doing something like video editing with very linear reads/writes.

Basically, it can reduce the potential seek distance on a drive (which helps, but not much) while greatly increasing the seek time from one partition to the other. Don't copy from one partition to the other.

indeed
it will have the same effect that partitioning any drive will have
limiting the degrees of arc that the arm will have to transvers if the seek is within one partition
and if you can actually figure ot what access pattern you typically have, concentrate the high access to the OD of the platter where youll have higher sustained transfer and lower latency
in the case of a RAID0 its just happens in tandem (with a 2 drive stripe)

Yeah, Ice said what I was too lazy and ignorant to elaborate upon, lol.
