Anyone Using Raid 0+1 ?

gamesaregood · 20 Jun 2007 at 00:55

Hello Everyone,

I currently have a SN25P Shuttle with a single Raptor 74gb 8mb Cache. I have decided to sell this and am trying to decide what to replace it with maybe go raid. I have been looking at the AAKS WD Range and like the idea of a couple in RAID

. But Can't decide if i would prefer the know that if my HDD Dies I can get the data Back from 1 or the Speed of 0 and then i remembered about 0+1 which from what I understand gives both.

Also on the shuttle site it only lists Raid 0 & 1, does anyone know if 0+1 is supported?

Anyone using this? Any Benchies and compares to Raid 0? Anyone got any Raid 1 vs Single Drive Benchies?

Thanks,

Michael

No clue, but how about a new Raptor 16MB, they are far faster, some new SATA300 HDD's can now beat the older Raptors in transfers (not sure on seek), not sure on size but you got 3 choices and prices have fell over last year.

Yeh thats why I've sold my raptor really. The newer drives are almost as fast apart from seek and have the added benefit of being a lot bigger. So I think Raid might be fun to have a play with

Does anyone know how much space you would have left from say a couple of 500gb Drives in Raid 0+1? Would it be 500gb or 250gb?

Thanks,

Michael

I think you see 500GiG same as in Raid1, where as Raid0 would be 1000GiG. :confused:

you need minimum of 4 hard drives for RAID 0+1

I've done it before (used it for about a year).

Basically it is RAID0 with redundancy and can survive a 2 disk failure so long as they are from the same stripe. Otherwise it's just a one disk failure.

RAID0 speeds with single drive write speed.

e.g. I'd expect about 110MB/s read (based on perp tech drives) and about 60MB/s writes.

Thanks for all your help

But seeing as it requires 4 Drives it rules it out of working in my shuttle

So it looks like I'm back to deciding between a single drive, Raid 0 or 1... ah well never mind!

If it says it will do Raid 0 and Raid 1 then it probably won't do 1+0. This would normally be listed either as 1+0 or more likely 10.

gamesaregood get yourself a RAID 1 array, its always good to know you wont lose your data if one drive fails and you'll notice you have quite an improvement in seek speed too.
