965p-ds3 ssd low raid performance

[Jtaylor]

Need some help in getting my raid set up & running please. This has me pulling my hair out!

I have two intel x25-v setup in a raid 0 and they're not performing as well as they should.

motherboard is gigabyte 965p-ds3.

So here's a list of what i have done:
ACHI is set in bios along with raid.
Created the raid0 array with a 128k stripe size.
Went to install win 7 64bit and loaded the gigabyte 64bit sata raid drivers because win7 wouldnt detect my raid array w/o them.

I've also reinstalled windows this time loading the jmicron raid drivers released in march 2010. Still no dice, same performance issues.

It looks like my read speeds are capped at 170-180MB, which is what the drive is advertised as a single SSD. The drive write speed is advertised as 35MB, yet in these benchmarks, im getting 80MB writes, which would mean the raid0 is working in a way, i guess?


Here's a couple pictures of some benchmarks and device manager:

Any ideas?

You should reinstall, and this time use the Intel ports and drivers!

Put your disks on SATAII-0/1 Yellow ports, and use the Intel Preinstall drivers here

Of course align your array before you install too! Use an alignment twice what you would on a single disk, I use 1024kb offset with 128kb stripe.

Then be sure you install the Matrix program and enable Write Back Cache (Can also be enabled in Device manager, properties, policy - for the array)
