NVM Express standardize SSD PCIe?

With the arrival of new models whose performance SSDs come dangerously close to the theoretical limit of SATA 6 Gbps, it becomes urgent for the IT industry to develop a new standard. A working group, called Non-Volatile Memory Host Controller Interface (NVMHCI) Work Group and comprising 70 companies such as Cadence, Cisco, Dell, EMC, Fujitsu Technology Solutions, IDT, Intel, Marvell, Micron, Microsoft, NVELO, Oracle, Cot, PLX, Samsung, SanDisk, SandForce, STEC or Violin Memory has been established some time ago to study the possibility of using the PCI-Express interface standard for SSDs.

Some products already exist, but they fail to meet any standard. The group has just finalized the first version 1.0 of the standard MSL Express, a standard for describing the characteristics of a DSS in PCI-Express and provide some cross-compatibility between different products that meet this standard.

Intel already offers a Linux driver, while a Windows driver is currently under development, the first alpha version is expected in the third quarter of 2011.
