The Serial ATA Working Group has released the final specification of Serial ATA II: Extensions to Serial ATA 1.0. Internal storage devices such as hard drives, DVDs, and CD-ROM drives currently use Serial ATA 1.0. Serial ATA II is intended to enhance the standard and extend it to enterprise storage.

The release of the Serial ATA II specification is the first of two phases of Serial ATA II deployment. The Phase 1 specification concentrates on supporting server and networked storage markets. Phase 2 will concentrate on increasing performance so that storage enclosures can use the standard. Phase 2 will add enclosure-management services and backplane interconnect support. The Serial ATA Working Group should release the specification for Phase 2 in the second half of 2003.

The 100 members of the Serial ATA Working Group expect Phase 1 product adoption by mid-2003. Deployment of Phase 2 products should begin in the second half of 2004.
