WD will be demonstrating the first PCI Express hard drives at Computex 2014.
Enabled with key technology partners, WD’s prototype introduces the new SATA Express interface, a form of PCI Express technology, which is offered on recently launched Intel series-9 chipset motherboard platforms. The SATA Express interface provides a roadmap for faster speeds, lower power consumption, and increased flexibility for future OEM designs.
The road to the world’s first demonstration of SATA Express has been in development for almost 3 years. In 2011, SATA-IO, the group responsible for charting the future of SATA, announced that it was developing a new specification that would fundamentally change the core technology behind SATA by melding it with the more advanced PCI Express computer interface. In 2013, the SATA Express specification was announced; and just one year later, WD and selected partners have realized a prototype of what is expected to be the next generation of storage technology.
By moving to PCI Express, the industry marries the world’s most popular storage bus with the world’s most popular computer bus. This union provides a solid growth path to innovate new capability, while preserving the ability to plug legacy SATA drives into new SATA Express based computers. In another innovation, SATA Express allows cable connections with lower costs, by removing the PCI Express Sync line via SRIS (Separate RefClock with Independent SSC), which lowers the overall cable cost.
The SATA Express interface will be demonstrated in systems from WD’s key partners at Computex to show the operational interface with their new platforms. This new SATA Express infrastructure allows customers to work with SSDs, SSHDs, and HDDs on a single common bus.
