I have 2 WD Raptor 37 gig drives setup on a raid 0 array. My motherboard will support 4 sata divices. Can I install another sata drive as extra storage without it being included in the raid array? In other words I want my computer to boot to the raid array; and use the other drive for storage. :confused:

correct me if I'm wrong, but wouldn't adding a non-RAID drive to a RAID system defeat the purpose of RAID? wouldn't you lose the benefit of the RAID setup??

I don't want to interfere with my boot drive(raid). I just want more storage and also I noticed in my bios that I can enable or disable each sata port.

It depends. Some raid controllers like nvidia raid will allow you to use raid and non-raid drives connected to the sata controller. Real raid cards do this as well. I have just the setup you have described; two drives in raid0 and a third drive for backup. These are connected to a promise tx4300 sata raid controller.

Other onboard controllers like via or promise will NOT allow you to do what you are trying to do. They function as a raid controller OR a standard ide controller but not both. Some mb have more than 1 sata controller so you can have one for raid and the other for standard ide.

I can't find out from MSI about this but it is an nvidia Nforce 4 4x board with nvidia raid controllers and like I meant to say before, I can enable or disable raid on each sata port.

You can do it. Nforce4 is probably the best of the onboard controllers.

Ok, that settles that and I really appreciate all your help(y) Now do I have to have an os installed on this extra drive to use it for storage?:D

No definitely not.
Edit: You do of course need to partition and format the drive.

Thanks a million for all your help. I went ahead and disabled raid on one of my sata ports and installed the drive on it, then I took a copy of Max Blast for windows and formatted the drive. It gave me the option to make this a boot device or storage device so now I'm up and running. Thank you so much and have a great evening.:)

Glad you got it to work.
Just a thought; I would use windows disk management to partition and format the drive rather than the mfg software. The reason is that sometimes the mfg software will install a drive overlay on the drive.

Don't mean to butt in, but what's wrong with a drive overlay? What problem does it present?

Drive overlays very often do not work well with other drives. If you put the drive [with the overlay] in another system to try and recover files, you often run into problems.

IMO a drive overlay should never be used. If there is no bios flash available for the board to support the large drive, then go with a controller card.

I don't know much about drive overlay, I just know that I formatted the drive using windows and I used Max blast to set it up as an extra storage drive. I guess my bios supports large drives even though this one is only 80 Gb. If I remember correctly, you only run into to that with drives over 137 Gb. Thanx Guys.
