Raid 0+1?

post #1 of 5
Thread Starter 
Does RAID 0+1 offer the same performance as RAID 0 with the benefit of backed up data? Or do you suffer a loss because of the mirroring?

I want the speed of 0, but I CANNOT risk losing any data so I thought the striping and mirroring would be the best setup.

Yes, as far as I know, RAID0+1 does offer backup, but obviously, the hard drive needs to be equal or greater than your array

Oh yea I know, I think your supposed to have 4 identical disks for the mirroring and striping combined... I just don't know if there is any performance hit with 0+1

For performance gain plus redundency.... go for 0+1 or 5. You can also do RAID 10 if you can run it.

0+1 requires an even number of HDs and half are dedicated to mirroring. Expensive but reliable without too much overhead. Easy recovery as well. RAID5 just requires 3 or more drives. Only one drive is dedicated for parity. Cheaper hardware cost, but harder to recover and parity calculation decrease its performance a bit or takes additional processing.
Once again...

Wow thanks for the info duckie! I would be perfectly fine running RAID 0+1 as I'm thinking of buying 4 Seagate 320GB SataII's (16MB cache) for it, but what is RAID 10 if I may ask?
