New RAID setup

[justinmg]

I have set up two Samsung MLC 64Gb drves in RAID 0, on a Silicon Image based 3132 PCI E card.
I have freshly installed Vista, and run SSD tweak, and turned on write cache and advanced performance. I have a stripe of 128. I dont know what an offset is or how to change it!
I am getting 130 MB/s read, which seems pretty low to me. Is there anything else I should be doing?

I am using the card as there is no onboard RAID. The figures look better than for a single drive, so I guess I will just have to put up with it.
Cananyone tell by looking at the smaller data chunks if this setup as it is will be better than non RAIDed drives for general office use with some video and photo proccessing?
