RAID problem

[fastman]

I have Raptor150 as the boot drive. I have two 300Gb I would like to strip. I built the array and can see it during the boot process (healthy 598Gb) and such. However in Windows I only see one disk! Saying the other one is Unallocated? I have formated them both and left them as Basic drives.

I'm using an Asus AN8 Deluxe SLI and trying to use the Silicon Image controller.

Different subject but maybe since I have an Opti 165 I could just do a software RAID and be done with it, would I see much of a performance loss if I went the software route?

Thanks in advance.

Just FYI, the data may not be recoverable if the software RAID fails.

Is this a RAID 0 array? It sounds like it since you mention striping. You do realize that a RAID 0 array appears as one drive in Windows?

You say you only see one disk in Windows, is that your Raptor or is it one of the 300GB drives? What are the sizes of the drive you do see and the unallocated disk?

Did you install the SI RAID drivers in Windows?

AFAIK, the SI's on PCI, so that'll be a bottleneck with faster drives, and you might get a bit better performance by using the nVIDIA RAID. I'd suggest 32k for 2-drive RAID 0. RAID 1 might be faster for reads with SI -- you'd have to bench it.

Again, usually you have to have the drivers installed at the OS level, then the RAID array appears as a single drive of the composite size (x2 for RAID 0, x1 for RAID 1). Enable the RAID in BIOS before installing the drivers. Thereafter you treat it as a single drive at the OS level, formatting it, etc., as one device.

I just got back in town from snowboarding in Vail, Co.:thumbsup:

Yes this is a striped array RAID 0.

The boot drive is the Raptor(150Gb) and I see it. I only see one of the supposedly striped drives (300Gb). Yes I am aware it will be seen as one drive, although I should see it as approx 600Gb, not 300Gb.

Let me look into this and I'll get back to you, rest time:roll:
