Just got it this week and set it up to replace my now ancient Raptor X 150GB. (you know the one with the gimmick window so you can "see" the drive in operation...even though its in your case and you'll never look at it...) Had read up on the marvell issues and was fully prepped to run it on sata 2 instead but I decided to give it a try on the 9128 for giggles. turns out the marvell aint too shabby. OCe'd the pcie bus to 115 and I'm getting 450 reads, 275 writes. Sure sure well less than true sata 3 advertised speeds but still more than it does on sata2. any ssd was going to be leaps and bounds better than the raptor but I can't say I'm disappointed that I paid a few $ more for the 840 pro. I kept my raptor for 8 years. I wanted longevity + speed. Seems like the 840 pro will give me that.
