Alienware Desktop Aurora-R3, 3TB disk in raid
I have an Alienware Desktop Aurora-R3 and I want to install 2 3TB disk in raid (mirror). First my disk were detected for only 746GB so I found I have to update inter RST. I did and in my windows os, disks are detected correctly. But I want to configure my raid from within the bios, using RST option ROM. I updated my bios to the latest version, A06, but is still uses RST option ROM v10.0 which has no support for big disks, only 10.1 and higher has. Where can I find the bios update with RST option ROM v10.1 or higher included? Should'nt DELL provide this on their drivers download support page?
No Events found!

The chipset in the Aurora R3 will not support RAID creation with HDDs larger than 2TB. However, you can still create the mirror raid via software once windows is installed correctly in one of the HDDs.
How?
Simple, once the OS is correctly set up, download the Intel Rapid Storage Technology, and use it to create a mirror RAID from within windows.
Hope this helps

So I executed the steps as you described, in RST I saw 2 disks of 2795GB but when I created the mirror it gave me a disk of 747GB. What went wrong?

If it's not correctly created through the IRST it means the hard drive's controllers are not being read correctly and therefore it'll show lower sizes. That's because the motherboard wasn't designed to support HDDs larger than 2TB.

but before I created the raid, the disk was read correctly. Only when I created the raid volume, it changed. So I can't use a raid in my system then?
