RAID Controller

Using PCI-Express X1 slot, with RAID 0 on two SATA 500gB / 32mB drives. Will the fact of using an X1 slot and a controller card, slow down my HDD's, or can they keep up just fine?

Thanks.

(No, my MOBO does not support RAID)

x1 is 2.5Gbps = 312.5MB/s

granted there is some overhead so you'll never reach that, but about the fastest you can hope a standard HD to be is 100MB/s

assuming RAID0 perfectly doubled that transfer rate, 200MB/s would be still be quite a bit below it's max capacity
 
You'll be perfectly fine. With those hard drives (which I guess will never reach transfer rates above 80MBps), I wouldn't hesitate to set up a RAID 5 array with 4 or 5 drives.
 
assuming you do have sata ports on your motherboard that just aren't raid, you might consider software based raid-0
 
1. i wouldn't do it for your boot drive no matter what
2. best case is if you have a pro/server version of windows

3. if you happen to be using linux there are a ton of options too, but i'm not that familiar with them
4. if you have xp home, you can TRY hacking the support using this guide, but beware it's rather old and files might have been updated since then:

the other question you have to ask yourself is: is raid-0 really worth it?
