The 5mm hybrid disk is designed for the thinnest ultrabooks, it's developed in cooperation with Intel and Microsoft and features a new, smaller SFF-8038 SATA connector. Bright Side of News had the opportunity to shoot some photos of this ultra-thin HDD.
Western Digital will be working with OEMs and ODMs to work on developing the connector standard further and to determine whether or not the connector will be a direct connect into the motherboard or a ribbon cable. In addition to that, the Hybrid drive version of these drives will be the Black Edition. The Blue Edition is the 500GB hard drive that does not have any NAND flash and is just a 5mm drive.
