If you have a quality HW raid controller with proper performance (and far fr=
om all have good performance) you cam definitely benefit from a battery back=
ed up write cache on it, although the benefits will not be huge on raid 0.

Unless you get a really good price on that high performance  HW raid with ba=
ttery backup, it is probably not worth it for raid 0.

When that is said, raid 5 is pretty speedy as well with a good controller wi=
th battery cache so don't rule that out if you have the controller anyway an=
d may save you from some manual recover operations..

Regards,
Terje
