In some situations RAID0 would be faster, primarily working
with large files. In more typical generic PC/windows uses
the performance difference isn't much. In some situations
where you have multiple revisions of a file you can achieve
a performance boost by instead having one drive hold the
source file and the other be the destination after it's
edited/processed/etc to output. Leaving the two drives
separate you can also divide up I/O between OS,
applications, pagefile, temp files or application scratch
space... it really depends on how you use the system which
strategy works best and which files to put on which drive.
Since RAID0 has at least double the risk of data loss I
would not recommend it unless you're regularly making
backups of the data, which of course we should all do anyway
but maybe twice as often since there's twice the risk. I
don't recall now if your RAID was from a motherboard
integrated controller or an add-on PCI or PCIe card.
Personally I don't like setting up an array that depends on
the motherboard (plus CPU, memory, etc) all working, I find
motherboards to be the 2nd most common source of failure in
a system after PSU, maybe fans would be first if counting
sub-components but several parts might have failure-prone
fans.
Unless it were a RAID1 array where any other controller can
get the data off, for others I would prefer a PCI/PCIe card
so the set of drives plus card can be transferred to another
system should the need ever arise. Otherwise you might face
a situation where you have to buy a compatible motherboard
again, though from a cost:benefit standpoint if it didn't
fail soon it might be more appealing to do an upgrade if the
board were to ever fail, especially since older generations
of hardware tend to be slim pickin's, most of the lowest
priced sellers sell out of decent gear within a year or two
leaving only the lower quality boards until they're so old
that the remaining stock ends up at surplus 'sites.
