In the last few weeks the tide has started to turn when it comes to the Crucial RealSSD C300 and SandForce drives. We have tested the 128GB C300 and final production SF-1200 drives in both 100 and 120GB sizes and determined that most users will have a better experience with the SandForce drives in this capacity. When move to the 200, 240 and 256GB capacities the leader is still the C300, but only by a small margin.
In time more SATA 6G drives will come to market and eventually everything new will be SATA 6G and SATA II will be a standard for the history books. If you are starting to look at drives using native SATA 6 now and don't want to spend the kind of money needed to have onboard 6G compatibility then the HighPoint RocketRAID 640 is a good place to start since it offers good performance at a lower cost than most SATA 6G motherboards.
The only real problem we see is that once SATA 6G takes over the market Intel will have SATA 6G built into their ICH. We are hearing rumors that the next ICH will have eight SATA 6G ports instead of six SATA 3G, so at that time the need for a consumer class add-in card will decrease unless you are looking specifically to have a card handle your RAID arrays.
As it sits now, though, the only way to get SATA 6G is to invest in an expensive motherboard, expensive enterprise class HBA like the LSI card we use for testing or the HighPoint 640. Users on a budget will find the HighPoint RocketRAID 640 to be the cheapest solution. This option will allow the user to also keep their current motherboard, a big benefit if you have already invested several hundred Dollars in an enthusiast class main board.
