Author Topic: RAID 0+1 or 10? (Read 303 times)

Specc'ed out a puter for my father and he ordered it and rec'd most of it.

6600 conroe
Asus P5 something sli board (compatible with conroe)
Corsair Ballistix 2gb ram
bfg 7950OC
SB audigy ZS

4 160gb WD disk drives (sata 3.0)

I have my puter setup with Raid 0, cause its just a gaming rig. My father, however will use it for gaming and other things.

From my research he can go raid 0+1 (speed and good reliability) or Raid 10 (reliability and then speed).

Any + or -'s to either of these, and what is the difference in speed between them?

Thanks!

Im running a 0+1 setup on 4 WD 250 GB drives.

In both setups, (01 and 10) you will get about 2x write (same as raid 0) and about 4x read (2x raid 0).

As far as your performance is concerned, It will more likely come down to the hardware and what it supports. If your board recommends a specific setup, you'll want to use that setup.

As far as reliability is concerned, neither should really be considered superior. In both cases a drive is equally likely to fail (not from raid configuring, but from ordinary drive failure) also in both cases, after the drive fails, the rebuild process is identical. Insert new drive and tell computer to rebuild your array. It will copy the mirrored disk to the new disk.

Overall, i really dont think there is a significant difference, which is why many boards provide support for 0+1, or 1+0, but not both. (some boards will provide both). If I had the choice though, I would do 0+1 again. Ive had a drive fail and the rebuild was rather quick and painless.

Thank you... thats what I needed to know.

If you replace a drive, does it ask you in windows if you want to rebuild the array, or is it done upon bootup in Bios area?

Im using an ASUS Crosshair board. As far as rebuilding the array, I told it to rebuild at boot, the computer booted up and rebuilt in the background as i did my own thing. I did find however, that my board included 'MediaShield' software. It appears that I could have told the computer to begin rebuilding from the software after windows had already booted as well...might have been easier.
Once you lose a single disk, the computer takes about 30 seconds longer to boot (while searching for missing disk) but worked perfectly on 3 disks for 2 days while i sorted out the problem.
