I have changed my mind on the RAID 5 for my storage. I have a great deal on 2TB storage and will be using Two 2TB drives in RAID 1.

Can my Area 51 BIOS/RAID controller support two different RAIDs at the same time? My example setup would be like this:

RAID 0 - OS   (I currently have this RAID installed now)

RAID 1 - Storage (What I want to Add)

Any advice would be appreciated.

It supports Raid 0+1 but I do not have any documentation  on how to set it up.

@JoeCrab,

May I ask what your Windows Experince HDD Score is with those 2 SSDs in RAID 0? Do you happen to remember what it was with just one? I'm thinking a SSD will be my next upgrade. Only my OS and main programs are on C: (I've purposely been keeping it fairly small as I've been loading software).

Thank you both Chris and Tesla for replying.

I went to Dell.com to customize a new Area51 system and I was able to add a RAID 0 for OS and RAID 1 for additional storage. So if Dell would let me spec that out, I would assume my BIOS/RAID controller would work.

I am planning on mirroring both my 2TB hard drives. I aslo have a APC 750KVA UPS for my system and a APC 600KVA UPS for my montiors and router. 

A tradional RAID 0+1 is a little different than what he is talking about.

I don't know if it will work, but if you have the drives on-hand just give it a try. Be sure you have a good UPS on the system.

I you are going to be running 2TB drives, it's smart to to keep them constantly backed-up because they aren't very reliable and that's a lot of data to lose all at once.

Tesla, I looked at a few screan shots i used and I beleive my WEI score for a single SSD is 7.3. With two SSDs in RAID 0 it is a 7.7

Hope this helps. BTW the SSDs are the best upgrade I have done with any system that i have owned. My OS boots fast and my Games Map loads are insane! 

Thanks. Yes, that would put my HDD score into the 7's ... along with the rest of my scores. A 120gb would be perfect for me (for now, and room to grow).
