I use a Corsair Performance 256Gb SSD. It's only SATA2 but it is definitely faster especially when booting. If only the Marvell chip would run like it is supposed to we could get some real perfomance gains. Actually I noticed that this past week Crucial has dropped the price on their SATA3 SSDs. Very nice drive and 128Gb is only £230 now. Was £314.
