Intel Broadwell could feature SATA express Interface

Intel Broadwell could feature SATA Express Interface

We are months away from Intel’s “Haswell” and 8-series “Lynx Point” chipsets being released but we are hearing speculation today that is jumping ahead of Haswell and straight to Broadwell. Speculation is that Intel Broadwell could feature SATA express Interface to generate faster speed. Since Haswell will bring the 1150 socket, it is possible that Intel’s Broadwell could also use it to make Haswell chips compatible.

According to a road map slide (pictures below) is that Intel’s successor to Haswell will include at least two models, the Z97 and H97. Z97 will be for enthusist and the H97 for the more mainstream computer users. With this series of chipsets Intel could introduce SATA express. We know Intel’s 8 series chipset is bringing SATA 3 to all of its ports unlike earlier chipsets that supported a mixture of SATA 2 and SATA 3.

Broadwell roadmap

According to SATA-IO.org this is what SATA Express could bring us:

SATA Express is a new specification under development by SATA-IO that combines SATA software infrastructure with thePCI Express® (PCIe®) interface to deliver high-speed storage solutions. SATA express enables the development of new devices that utilize the PCIe interface and maintain compatibility with existing SATA applications. The technology will provide a cost-effective means to increase device interface speeds to 8Gb/s and 16Gb/s.

Solid state (SSDs) and hybrid drives are already pushing the limits of existing storage interfaces. SATA Express will provide a low-cost solution to fully utilize the performance of these devices. Storage devices not requiring the speed of SATA Express will continue to be served by existing SATA technology. The specification will define new device and motherboard connectors that will support both new SATA Express and current SATA devices.

SATA-IO expects the SATA Express specification to be completed by the end of the year.”

SATA-IO has SATA 3.1 but could make this SATA 3.2.

SATA express  in laymen terms is that the SATA link layer would function over the PCIe physical layer. Intel Broadwell equipped with SATA express could be backwards compatible and could reach upwards of 1000/MB of bandwidth.
