There’s no doubt that Serial ATA storage is hitting a wall when even mainstream PCs like the MacBook Air and VAIO Pro use the PCI Express interface to get around performance bottlenecks. It’s a good thing that SATA-IO just ratified the improved SATA 3.2 specification, then. The new standard centers on SATA Express , which lets SATA storage ride on the PCIe bus and more than doubles the available bandwidth to 16Gbps (2GB/s). Version 3.2 also brings support for the M.2 format , giving Ultrabooks and tablets access to SATA Express in a tiny form factor. We’re already getting a peek at what the new spec can do when M.2-based PCIe drives offer comparable performance, but SATA 3.2’s ratification should bring that kind of speed to many more PCs in the future.
