2 SATAIII SSD in RAID?

Yep, got twin 240GB Vertex 3s in mine configured for RAID 0 and they work fine. They'd work even better if the machine had two SATA 3 ports, but that's another thread...
Well mine does.
So you are limited to SATA2 speeds then? Why did you buy SATA3 drives?
Well mine does.

How about because the main port is SATA 3 and I get over 500Mbps?
My plan is to buy a new machine in the hope I'll get 6/6 and sell this one on eBay.

Is your config in your sig not up to date? Looks like you're running an SSD/HDD combo.
I have 2x SATAIII drives with the ODD port at SATAII. The two drives together give me faster r/w benchmarks than the best case stated specs by Crucial. So, there still is a benefit to a RAID0 pair with the disparate port speeds. At least that's how it looks to me.

so to clarify you have x2 sata 3 drives - crucial c300 over sata 3 interference - main HDD + ODD
What stripe size are you using?
What are your benchmarks of x2 c300 ssds in RAID 0?
How are u're random 4ks, as i have heard from many that random 4k (?write>read) have little benefit from a raid 0 setup - sata2/3!
my ideal would be: x2 vertex 3 max iops in RAID0 - 64-128kn stripe size
i would not even consider a drive with rubbish GC to raid0
other things that puts me off is reliability going down the drain once raid 0 has been instituted.

Sorry, I misread your comment and thought you were speaking from experience on RAID0 with 2x SATA3 ports.
Both drives are SATA3, ODD port is SATA2.

I ran RAID0 Vertex 1 drives in my old 2009 MBP for more than 2 years and had no problems with reliability, which makes it 100% more reliable than my current car which cost 110x the cost of a pair of Vertex 128 gig drives in 2009.
RAID0 is inherently more susceptible to failure than other multi-drive configurations, but that doesn't mean it craps itself at the drop of a hat. Any drive can fail. That's why we all make frequent backups, right?

thanks - really been itching to raid two 240gb ssds - but i only have 6/3 sata interfaces - hdd/odd so x2 v3 wouldn't make sense and the cost could not justify the expense.
I may, sell this machine and cop a 17" 6/6 setup - or pray for a logic board failure
also, x2 vertex 3 in rad0 would be amazing - drool over having >1gb/s seq read
however, i can cop x2 c300 for pretty cheap, and run them of sata 2 - again compared to x1 v3 and a c300 in optibay - would there be any significant gain in x2 x300 in raid0...
