First time setting up a RAID 0.

I bought two mushkin 240GB SATA 6Gb SSD'd.

I go into the bios, create a raid on the marvell controller bios then try to install windows and it says my drive has 447GB's.

Aren't I suppose to only see 240?

Also, what stripe size... 64k or 32k?

You should see something around 480, not 240. RAID 0 is striping. 240 would be for RAID 1 when you are mirroring the drives.

Stripe size... eh, I can't recall what the best one overall is. I know it really depends on what you do with the drive.

My stripe size is 128k. That is the average size. Server systems would want a lower stripe size while a pc used mainly for multimedia editing would want a larger size.

Here's a bench of my 3x Spinpoint F3's @ 128k stripe:

I have two muskins sata 6.0 on the marvell controller. I'm getting much worse results than that, though it only gave me 64k stripes as an option.

I might try and use the intel controller and see if that works out better.

I gather SSDs perform better with smaller stripe sizes.

Definitely use the Intel controller for SSD RAID rather than the Marvell... most boards with Marvell controllers have them connected by a 1x PCIe lane, capping performance under 500MB/sec...
