I'm assuming you understand what RAID is.

The below is a calculator/helper to get you the answer you need:

Which RAID you would use is based on the functionality of the server, the kind of uptime you need and the cost.

RAID 0 - no fault tolerance, do NOT use
RAID 1 - mirrored data on two drives
RAID 5 - single-disk fault tolerance, high risk of errors, consider RAID 6 or 10 instead
RAID 6 - two-disk fault tolerance, performance hit compared to RAID 10
RAID 10 - one OR two disk fault tolerance, generally acceptable for both redundancy and performance

@netcmh - please dont recomend this web page again ( as it has the wrong definition of RAID10 - we moved on from RAID1+0 and RAID0+1 as different companies had used them to mean the same thing, unfortunately they had become confusing.

So RAID10 was coined to clear up the previous ambiguity and is generally accepted to mean Striped mirrors, ie sets of mirrors (RAID-1) that are striped (RAID-0) unfortunately some idiot in Dell got it the wrong way round and perpetuated the myth.

SO RAID10 is defined as Striped Mirrorsets!

Incidentally neither of those sites show that RAID-5 is now deprecated for business use.
