The sata organization has a proposal for a new sata standard. The organization wants to sata specifications and the pci-express standard to unite in a new sata-express standard, which at the end of this year.
The proposal for the sata-express standard is derived from the Serial ATA International Organization, or Sata-IO, the specifications of the sata standards, develops and manages. In this consortium are all companies that have hard disks and controllers to deal with. With the new standard wants, the Sata-IO a uniform specification to develop for drives via pci-express connectors are connected, and moreover the compatibility with existing sata standards guarantee. In addition, you must use the new standard speeds of 8 to 16Gbps.
With the sata-express standard would also be two new connectors are involved. One of the connectors, a pci-express connector for hard disks, is suitable for use only to develop a pci-express-x1 – or -x2-cables. A second type of connector can not only with the new cables to handle, but also enables connection of two standard sata cables as possible. The connector should be connected to pci-express 3.0-lanes, but does not provide voltage for the connected drives.
The sata-express standard should be part of the sata 3.2 specification, and at the end of 2011 are defined. In mid-2012 have products with the new interface appear.
