I don't think so, only SSDs can cross the SATA2 Speed limit, since they are mostly(i mean all) out of reach its really no use getting SATA 3 now, it will be quite a few years for SSDs to hit the mainstream market, wasting money isn't needed, apart from SSDs most peripheral devices(all that use flash- like ipod, walkmans, cameras, pen drives) are yet to cross USB 2.0 limit so USB 3.0 is likewise useless, the technology needs to catch up first.sata 3 again need sata 3 HDDs to utilize the potential.
but again, there is a serious limitation. It's the speed with which HDD's arm can transfer data (signal).
sata3 will be very useful for something like WD black edition and raptors that are limited by sata2's bandwidth.
is it available in india ??
That's really cheap, provided USB 3.0 drives or SATA 3.0 drives will cost a fortune(SSDs).I guess not. BTW, it was priced around $30 and it uses pci-e x4 slot & this card also has 2 sata 6gb ports .For pics and more details
WoW! It's one hell of a great card IMO
