Finally theres talk about looking at other interfaces in addition to SATA. Its possible that we may see a PCIe version of SandForces 3rd generation controller.
Some interesting notes about future directions SandForce might take especially now that SandForce has been bought out by LSI. They are hard at work attempting to optimize other parts of their current memory controller technology (speeding up small random reads and writes). There might be another 2X performance gain to be had at least on the SSD front, but more importantly is the PCI Express market. Fusion-io has been the team to beat when it comes to integrating components and moving data across the PCIe interface. Now SandForce is looking to come out with a bona fide PCIe-SSD controller which up until now has been a roll-your own type affair. The engineering and design expertise of companies like Fusion-io were absolutely necessary to get a PCIe SSD card to market. Now that playing field too will be leveled somewhat and possibly now competitors will enter the market with equally good performance numbers
But even more interesting than this wrinkle in the parts design for PCIe SSDs is the announcement earlier this month of Fusion-io’s new software interface for getting around the limits of File I/O on modern day OSes. Auto Commit Memory: “ACM is a software layer which allows developers to send and receive data stored on Fusion-io’s ioDrive cards directly to and from the CPU, rather than relying upon the operating system”(Link to The Verge article listed in my Fusion-io article). SandForce is up against a moving target if they hope to compete more directly with Fusion-io who is now investing in hardware AND software engineering at the same time. 1 Billion IOPS is nothing to sneeze at given the pace of change since SATA SSDs and PCIe SSDs hit the market in quantity.
