The new OCZ RevoDrive Hybrid RC2 1TB is one of the fastest and most interesting devices of its kind, it needs no messy cables and utilizes a more or less unused PCIe 4X slot on your motherboard offering performance competing with two SATA3 SSDs in RAID 0 for under $500.00.
Just watching your computer turn on and be usable in 30 seconds or less is pretty sweet. And you can also see that even though the Kingston KC100 SSDNow has a much faster transfer speed, it had around the same amount of boot time as the Intel X25-M SSD.
