This is my first time raiding. I put 2 500gb Samsung f3 drives in raid 0. With a strip size of 128K and I short stroked it to 250gb.

My results aren't as good as others who raided this drive. What can I do to make it go faster?

btw my mobo is Gigabyte GA-890GPA-UD3H rev2
 
Is that one of those boards with new SATA 6.0Gbps interface? I hear that Samsung F3 series drives have an issue with it
 
Yeah its one of the new ones. This one is rev2, and the samsung f3 drives worked w/ the mobo right out of the box, on the Sata 6.0gps ports.
 
Really?,,, After some googling and finding the average speed of a single F3 I think thats about average for them in software raid 0, Are you just hoping to get Raptor raid speeds with those.
 
Well from pics of raided F3's I've seen, people average 200MB/s on transfer rate. Mine is averaging around 160MB/s, which I thought is low compared to theirs.
 
You are using a very small stripe size, which can introduce a lot of additional overhead. With thats sort of disk, you really should be looking at around 1-1.5 MB stripe.
 
There's no real reason to be putting the drives on the SATA-III controller. The Samsung SpinPoint F3 is a SATA-II drive. The ICH10R/ICH9R does a fantastic job running these drives in RAID-0 mode. Don't use Windows RAID, use the BIOS on the motherboard for ICH10R to create the array.

Here are my results when I was running two of these drives in RAID-0.

I'm now running 3 of them in RAID-0 and get between 300 and 340 MB/sec sustained transfer rates. This is on the SATA-II ICH10R.

I thought that might be the reason, I currently have it on the SATA III ports, I will try connecting it on the SATA II port and see my results later, thanks

BTW I didn't use windows raid, I did it through the BIOS
