Vertex 2 Raid 0 write speeds seem slow.

Does this seem right? I'm more than happy with my read speeds but shouldn't I be seeing better write speeds than this? I've got another computer with 2 HDD's in raid 0 that have better write speed than this.

Any help would be great. Specs below.

Operating System: Windows 7 Professional
MOBO: ASUS Rampage III Formula LGA 1366
CPU: Intel Core i7 CPU 960 @ 3.60GHz
Ram: CORSAIR DOMINATOR 24GB (6 x 4GB) 240-Pin DDR3
Storage: OCZ Vertex 2 120GB X 2 SSDs
RAID: Intel onboard RAID Controller ( RAID 0 )
GPU: GeForce GTX 560 Ti

Advertised Vertex 2 speeds are with ATTO & AS-SSD benchmark software.

You need to benchmark with AS-SSD.

Advertised AS-SSD speeds are "up to" 225 MB/s Read and 80 MB/s Write.
So with 2 drives in RAID-0 you're looking at max speeds of 450 MB/s Read and 160 MB/s Write.

Your CrystalDiskMark results of 470.4 Read and 158.8 Write seem to indicate that your RAID performance is ok.

Here's the link to the spec sheet for your drive:

Thanks for the input, AS-SSD gave me virtually the same results as Crystaldiskmark. Thought the read speeds were higher, haven't looked at the specs in a while. Thanks again for clarifying.
