I'd like to compare benchmarks and speed tests for the OWC Mercury Extreme Pro 6G and also see what kind of tool you guys use to measure the SSD performance and if I can improve it.
This is my configuration:

Macbook Pro Mid 2012 13.3"
i7 2.9 Ghz.
RAM 16 GB 1600 Mhz DDR3
SSD 240 GB OWC Mercury Extreme Pro 6G
Mac OS X Lion 10.7.4 (11E2620)

Not a good test. BM writes non-compressed data. Sandforce is not good with this data compared to Samsung and Marvel based controllers. You're going to be frustrated with your numbers. Run AJA and you'll peg 500+ read / 500+ write. But you need to create a blank partition to do it as Apple has screwed up the permissions on the volumes to allow a concise speed test from AJA.

I can't find AJA for MAC anywhere. You have a link?

Found this; http://www.aja.com/ajashare/AJA_KONA_System_Test_v2.app.tar but it doesnt work on my rMBP internal SSD, just any external SSD/HDD I plug in.

You mean non-compressible data...

You don't need to create a separate partition if you launch Aja as super user.

So, get root in a shell and use 'open' command and it'll work? Thanks for info if it does. Can't test right now. On 10.6.8 desktop where everything still works.

I opened it in Terminal, navigated into the the Aja system test folder in Applications and ran the executable with 'su ./' in front of the file name. Can't remember the exact file name ATM as not at the Mac to check

Navigate to directory and:

sudo AJA\ System\ Test.app/Contents/MacOS/AJA\ System\ Test &

does it. Thanks.
