Major equipment manufacturers are developing a new standard for SSD-drives
Probably, the word “large” in this situation does not quite fit - the apologists of the IT market, including IBM, Dell, Intel, EMC and others, have joined forces to create a new, high-speed standard for not very fast SSD-drives. You can imagine what forces are involved in the development of this standard. By the way, the working group that deals with all this is called SSD Form Factor Working Group. The interface being developed is called PCIe, and, according to the developers, this standard will be compatible with all drives with NAND standard memory.
In addition to these companies, smaller manufacturers also participate, including Micron, Molex, Emulex, SandForce, FusionIO, QLogic, IDT and Marvel. It is worth noting that for some reason HP does not participate in this project.
As for the standard PCIe (Peripheral Component Interconnect Express), it is a serial interface between the PC motherboard and various devices. Currently, a special expansion card is used to connect such devices, which significantly reduces the performance of the device. But PCIe provides for the integration of the desired interface into the motherboard, and the connectors are located right there on the motherboard. According to manufacturers, this allows to significantly increase the speed of data exchange, increase the overall energy efficiency of the system, and reduce heating.

Among other things, PCIe has a couple more advantages. For example, it will include interfaces such as serial-attached SCSI and serial-ATA. Companies participating in the project are developing an interface not only for custom SSDs, but also for 2.5-inch drives, which are commonly used in servers.
According to representatives of the joint development team, now research is being conducted in three main areas. The first, as already mentioned, is the development of an interface for connecting 2.5-inch disks. The second is the integration of connectors, the elimination of expansion cards. The third is on-the-fly support for disk replacement.
Experts believe that the new type of SSD should appear as early as the second half of next year, and the capacity of such devices on the drive-processor interval will be about 2 Gbit / s. Of course, SAS and SATA of new versions are slightly more productive, but for SSD drives this is a clear breakthrough.
