Setting 0+1 (or 1+0) or 2 disks, how to?

[flatlander]

I would like to partition my 2 SATA disc drives to a RAID 0+1 configuration, for speed with the system, and data protection for documents, etc. Can anyone direct me to a site with good instructions for this (assume that I am John J Newbie please).

ASUS P5N32-SLI SE del, 2 x western digital 2500Js HDD, currently in RAID 0. Silicon Image Sil3132 RAID controller/ NVIDiA Southbridge nForce 4 Southbridge.

raid (0+1) or (1+0) can only b done w/ 4 disks

u may want 2 try raid 5 if u want some data security...but im not quite sure how raid 5 works

could some1 fill me in?

does ur mother board support raid 0+1 and has 4 sata slots?

i would google for your answer

like others have said, Raid 10 or 01 is only available with 4+ drives in even numbers

Raid 5 requires min 3 drives, the data is arranged in parities.

Your only options for 2 disk arrays is Raid 1 or Raid 0

Back to Raid 5 tho, I'm not sure if this is still true, but if you want good performance with a Raid 5 array, you need a dedicated raid card that can do the xor calculations, otherwise your raid array will take cpu processing power.


If you want detailed answers look on Wikipedia

Swear i have heard that you can partition the 2 disks and array 0 + 1. The board supports 4 SATA, but I'm not too thrilled about having 4 drives.

i don't know where u heard that from... but that is totally wrong

u could get a new hdd, and get speed increase and data security

ur mobo supports raid 5

i belive the raid is done by the nroth bridge
so it won't slow down like software raid does
not quite sure tho

Actually I know where you heard that, cuz I was under the same impression for a long time...

HP Servers can run (or at least it SAYS it can) 0+1 with only 2 drives. But I believe that its simply a default selection and if you have only 2 drives, it'll just do RAID1 (mirror).

You do indeed need 4 drives minimum for 0+1.

Some of the array controllers say you are running 1+0 when you create a RAID 1 array with two drives. This can later be expanded to 1+0 if you add two more drives.

It just seems like an oversight on the terminology for them.

OP, partitions have nothing to do with RAID. You partition after you create your array.
