Inception raid!

post #1 of 6
Thread Starter 
Hi everyone,

I've been thinking about this for a while now. Would it be possible to do a raid in a raid setup ? i.e. I have two 60gb ocz vertex 2's in raid 0 right now. If I were to pick up a 120gb vertex 3, would it be possible to raid that up with my current raid array ? So basicly what I was thinking about is:

2x 60 raid 0 = 120
1x 120 (dual 60's) + 1x 120 (single vertex 3) = 240 ?

Is this even possible or has my brain been seriously damaged by Inception

I know that if this would be possible, 3 drive raid 0 would mean a bigger chance of losing my datas. And speed wise I think that dual vertex 2's 60s come pretty close to one vertex 3 120 ?

P.S. I'm using the onboard raid of my Asus P8P67 EVO mobo.

Yep, what you're looking for is a Spanned RAID array. They're not very stable though.

One drive goes and that's it. Raidception.

Do you have any experience with this? And would it be possible with nowadays mobo raid controllers, or would it require a dedicated raid controller?

Cheers

That would require asynchronous RAID - no raid controllers support it AFAIK - you can't use different capacity drives (due to access times, synchronous data etc.) in RAID array - in theory it shouldn't matter with SSDs but no controllers support it.

But also you're talking about RAIDING SATA2 and SATA6G which is definitely not possible, because the drives would have different speeds, access times etc.

Rather sell you're two Vertex 2 60GB and buy another Vertex 3 120GB - shouldn't actually cost you much at all.

EDIT: You can span but that doesn't give you performance, it just creates one big drive with no performance increase.

i really wanted to do this, except have two drives in 0 for speed, and another drive in 1 for redundancy.

but having raid + a second drive to store all your other stuff on, install games on, and all the junk is perfect.

I think you could raid the pair of 60's together with your motherboard controller. Then raid that array together with the 120 in software.

Personally though I would sell the 60's and buy a 120, make everything a lot easier.
