Keep in mind that OWC is current state of the art technology compared to the 2009 Apple stock SSD. So I would not expect the same performance difference between Apple's current 2011 MBP SSD and the current OWC Mercury Pro.
I am looking forward to your benchmark results with SSD's in MBP 2011.
I'm really surprised at both of these Xbench scores. They seem abnormally low for SSD. Is there some setting you need to adjust in OSX to tweak the read/write speeds for SSD? Or am I misunderstanding the data?
According to OWC, the 240GB Mercury Auro Pro MBA sequential read should max out at 285 MB/s and sequential write at 275MB/s. [

I get between 500-550MB/sec sequential read for dual Intel X18M in Raid0 in my windows laptop. I imagine it should be around 250 MB/s or so for each one individually.
