raided 2 samsung f3, result not good

[binaryfuzion]

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

 

[binaryfuzion]

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.

One f3 drive averages 100-130. Two raided in zero = 200-260.

Seems right to me!

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
