HI,
I just want to know if is it possible to do raid 0+1 (raid 5) with this MB.
For me Raid 0+1 means 3 HD and performance of Raid 0 stripping an raid 1
security by error control.

1) is this feature enabled with the promise controller
2) where can I find the settings and the performances?

Thank's

AFAIK raid 5 is not available on the promise controller.
RAID 0 - faster reads / writes, greatly reduced data security
RAID 1 - faster reads, mirrored data.
RAID 0+1 - best of both worlds, requires 4 drives minimum
RAID 5 - faster reads, slower writes.

If you can afford it and want resilience to drive failure (not human
stupidity), use RAID 1.
RAID 0 should not be used unless you are prepared to lose all data in the
event of a drive failure.

With the reduced cost of drives and increase in performance of RAID 0+1 (aka
raid 10), RAID 5 is becoming less common.

You can buy add in cards that will do raid 5 very well. See
www.tomshardware.com for some reviews.

To have resilience to human stupidity, you need a good backup system,
undelete utility, user education, and security...
 
Thank's for your advises....

I could understand the fear of raid 0 in days past but with DVD burners
and media being sooo cheap who cares if you lose it? Sure don't use
on a business machine and if you do taxes, Quicken any other important
stuff you should already be backing up to something other than internal
drives anyway.

I have two 160 gig drives in raid 0 and I have everything on em backed up.
 
According to my (English language) manual, Section 5.6, page 5-19, the
Promise RAID controller will support RAID 0, RAID 1, RAID 0+1, and
multi-RAID (not sure what that is!), using the SATA connections & the
parallel RAID connection.
