AAbout the soft raid I did not utilize this I used disk utility from Yosemite with hex editor to make it run in El Capitan to make a raid 0 which I made a video of that too on the same channel where I am showing my disk speed with raid 0 with black magic speed disk test

Again, what speeds did you achieve?

Is there some reason you can't just post the speed here, did you forget?

How many megabytes per second, its an easy question if you have done it.

Do the test again, photograph it with a note that says November 15 ASC test.

your welcome my friend and if you have any doubt like some one has in another discussion telling me that I don't get those speed here is my system setup

You're welcome.

Your welcome JDW1 if you have any more doubts how to upgrade your system go to OWC I got all my stuff there from them the tools and the adaptor for the 3.5 to 2.5 adaptor from newer tech and the data doubler which you have to look at your identifier which is an iMac 11.1 or just look at your system at the upper left corner about this mac.....

Yes it has dual channel Sata 2 there is even a guy explaining it on youtube which he dismounted the logic board of his late 2009 iMac 27 inch.

in the optical bay area there is a rumor saying that if you get a 6Gigabit SSD it will run as a Sata 1 not Sata 2 I think that is negative it will run on Sata 2 I got Samsung SSD so both are running on a Sata 2 controller....
