I want to use an Intel 510 as my boot drive on a X58 (ICH10R) board and use 3 2TB drives in Raid 5. Is that possible? I think the settings simply say "IDE" "RAID" and "AHCI".

So I choose "RAID" right? would that mean I am not in AHCI mode for my SSD boot drive?

Is what I am aiming to do possible?

Thanks a bunch.
 
thanks for the reply.

so is it possible to have the SSD by itself as a boot drive and then use the 3 2TB drives in a RAID 5 array? haven't tried it yet since am waiting for the hardware to configure it.
 
Yes. If you set the SSD up as RAID, but you don't make it a member of an array, a TRIM capable OS can send it it TRIM commands.

I don't recommend RAID 5. For the small savings in price (one additional disk), you will pay with both performance and reliability compared to RAID 10. More reliable with three disks, would be to put two in RAID 1, and use the third for backup. (RAID, of coarse, is not backup)
 
Thanks again for the info.

I see your point with RAID 5 vs RAID 10. I don't quite get your recommendation with the 3 disks to put two in RAID 1 and use the 3rd for backup. could you clarify this?

I was speaking of reliability only.

RAID, even a simple mirrored set, is not backup. If an error (or erroneous deletion) is written to one drive, the same error will be present in the mirror. So I was saying that two drives could be used in RAID 1 (to get the dive failure protection) and one drive could be used in single disk mode to back up the RAID 1 array (to get backup protection) This is still not perfect reliability if all 3 drives reside in the same box. For example, a fire could destroy all 3 disks at once. But it is more reliable than the same disks in RAID 5 with about the same performance and only a little less capacity.

Method 1:
If you choose RAID mode, then after POST it will prompt RAID config that you need to press ctrl+i or something like that to get in. Once inside you can specify which drives are raid member. In your case, it is the 3 HDD, meaning that the SSD is a non-member. After initial setup, you probably will never go in it again.

Then you go back to bios as it will than see the raid drive. Select the SSD as boot drive.

Method 2:
Select IDE or AHCI and setup software raid within windows.

IDE is the most native interface while AHCI mode is newer. With AHCI some newer features will be enabled if the drive support it. Raid mode usually means RAID + AHCI.

You cannot switch between modes after OS installation without tweaks.
