As part of the SNIA Solid State Storage Initiative, the PCIe SSD Taskforce is taking an SSD-oriented approach, and isn't promoting a particular interface or technology. We are aiming to educate the market about PCIe SSDs and fill any holes where current standards may be lacking.

As an old fart, this has some appeal to me... but exactly which bus would you choose? (I remember that problem too). PCIe is really quite elegant, fast and supported by most architectures including some ARMs and a few FPGAs. Apart from maybe running code directly out of flash, what application would benefit from a direct mapped approach versus smart intermediate controller than can take care of bad blocks, wear levelling etc?

What is their charter?

You might have missed that HP and Fusion-io are key promoters of the SCSI Express standard. In fact, HP demonstrated upcoming SCSI Express products with Fusion-io last November at HP Discover in Vienna.

Connecting Directly to the System Data and Address Bus is the best and Fasted way of Connecting the Memories with the Host CPU. PCIe is still an intermediate way of doing it. If Intel, Microsoft, Apple and AMD come together and work of the interface standard for directly connecting the Flash/SS Drives with System Data and Address Bus then it will really change the way computing systems works today. The latency in the HDD access was hiding the latency of the interfaces like ATA, SATA and SCSI interfaces but that is not true in case of Solid State Memories.

Good article, but it missed a new activity sponsored by the SNIA Solid State Storage Initiative - the PCIe SSD Taskforce - that has its first meeting on April 9. Take a look at www.snia.org/forums/sssi/pcie.
