I just built a system on an Asus P8Z68 Deluxe motherboard that includes two Intel 510 256Gb drives. One is drive C and the other is drive D on ports 0 and 1 respectively of the Intel controller. I am not using the Marvell controller. I was dissapointed in the Primary Drive WEI score so I opened the Intel RST Management panel and noticed the C drive is reporting a SATA Transfer Rate of 3Gbs while the D drive is reporting a 6Gbs transfer rate. The only difference between the two drives is the C drive is running the PWG2 firmware while the other one is running the PWG4 firmware. Does anyone have any thoughts on what may be holding this drive back?

Yeha RAID 0 is amazing with these Sata 3 drives, I spoke to both an Itel and OCZ tech and they both said that GC is superb on these drives that performance will degrade very very min and over a long time. And if it becomes an issue, you can always do a low level format and back to new

That's some blistering speed and I hope it continues to work for you. I may opt for your route in the future but I want to give Intel a chance to fix the underlying problem. However, I am not known for my patience so they can't take forever.

Where exactly do you enable Disk Data Cache in? I don't see an option with my Intel Rapid Storage app... is it with the toolbox?
Edit: Never mind is on the actuall array... I found it let me test it.

Ok so it appears that the DIsk Cache was enabled however the Wite-back Cache was not and after enablling it I get much better numbers on 4k Writes:
Compared to (Write-back Cache Disabled)
Now if I can fix my 4 K reads! I know there has to be something left to tweak.... that said this forum was pretty awesome the people that contributed to these two threads have really helped me not just fix my issue but rather learn and understand much more about SSD, thx RickiBerlin, ianpugh and Bannon
Here's a great guide I followed as well:
