Multiple Layer RAID Setup

[JoshArgent]

Hi,

 

I want to know if its possible to have a multi layer RAID setup which allows me to pool hard drives together in a RAID 0 setup and then pool these RAID setups into a single RAID 1 setup which will allow me to have an up-to-date backup of my RAID 0 pool.

 

I have created a diagram to demonstrate what I want:

 

I current have a Gigabyte GA-Z97X-SLI motherboard which supports RAID however I have read that it would be better to have a separate RAID controller because if I was to change motherboards its unlikely that they'll have the same type of RAID controller in-built so would be incompatible.

 

I'm not looking to spend much at all on a RAID controller if I can help it.

 

Thanks for reading,

Josh Argent.

RAID 10 is what you want

 

If you had 4x4tb drives, you would have 2 Drives in raid 0 giving you 8TB, and then that would be mirrored across to the second set of drives - it can sustain 2 drive failures of any 2 drives

I've been wondering the same thing myself. So Raid 10 is Raid 1+0?

yep

yes. same goes for RAID60 = RAID 6 +0

 

and yes RAID01 is different from RAID10. the order of the layers is what differs.

That does sound like what I want however the diagram I included shows what I want in the far future.

What I will start with is 2 SSDs and a single 1TB HDD which can then be expanded in future. And I believe that RAID 10 requires a min of 4 drives?

you cant expand a RAID without redoing it from the beginning. you seem to not have any experience with RAID and thus I'd simply recommend to not bother with it. For SSDs it's not gonna give much improvement anyways and RAID is not a form of backup! just a buffer for service failure in a 24/7 environment.

Not sure you can do that, and you cannot just change RAID types on the fly without redoing the whole thing

 

You could manually back up the RAID 0 SSD array to the drive but I dont think any RAID levels will cover what you want to do

also you should have posted this thread in the storage section instead of CPU, MoBo and RAM
