Hi Matias,

This looks really interesting and I'd love to get involved.  Do you
have any recommendations for what hardware I should pick up?

Hi Joe,

The most easily available platform is OpenSSD
(http://www.openssd-project.org). It's a little old, but still very
functional. When there's a good firmware implementation, I think it will
be easier for the custom SSD vendor's to jump on board with their own
firmware.

Is this something that would make sense to use for accessing the NAND flash that's being used on routers nowdays? Talking with the OpenWRT folks, they are having trouble supporting those devices because the flash may contain defects and squashfs doesn't work in such an environment. This appears to be the one remaining problem preventing a lot of new routers from working.

If this can work as a shim layer between the hardware and the filesystem for OpenWRT, you would gain a very large userbase rather quickly.
