Default Raid 0 scaling with 1,2,3 - 60gb Vertexes

Copied form my post on the OCZ forums:

I ran a series of benchmarks with 1,2 and then 3 Vertex 60gb in raid 0. I used Crystal Diskmark 2.2 as it was the middle of the road results between the abysmal HDTune scores and the amazing Everest and AS SSD scores. The drives are flashed to 1.42b and I ran the Sanitary_erase before each setup. I ran the tests twice, using the 1024k default vista/win7 alignment and the 128k alignment.

Test system:
Watercooled
EVGA X58
OCZ 1600 7-7-7-20 DDR3
i7 920@4.2ghz

Here are the results:


My conclusions:
Either alignment is fine. The difference was minimal and within error margins on the tests.

The sequential reads don't scale as well as the other tests. But to me they are the ePeen stroking theoretical scores anyways, not encountered much in the real world
.
512k scales nicely.

Random reads dont scale at all. They still fly though compared to mechanical disks.

Random writes scale like a mofo, over 3 times. This is where your old hard drive crawled and where SSD's make your system fly.
