crookedvulture writes "SATA-IO has devised a couple of new storage interfaces optimized for solid-state drives. To serve high-performance SSDs that are fast approaching the 6Gbps ceiling imposed by the current Serial ATA specification, the SATA Express standard will meld the Serial ATA software stack with PCI Express to offer up to 16Gbps of bandwidth. SATA Express isn't expected to be completed until the end of the year, but the new uSSD standard looks to be ready for prime time. Designed for tablets and ultraportables, uSSD sticks with current 6Gbps speeds but ditches traditional Serial ATA connectors, allowing SSD controller chips to be soldered directly to motherboards. SanDisk already has a 128GB uSSD primed for ultrabooks."
