... build an SSD from a bunch of flash ... how big would it have to be to
be useful to 'see how it could be done?' ... is a gigabyte enough? you could take an OLPC XO-1, use the NAND flash therein, with jffs2 ... and 1.3 million of this configuration have been deployed. ;-)

Indeed. And the kernel already has more than one FTL implementation, which lets you do this silly fake-disk thing on top of raw flash and then use a 'standard' file system on top of that, just like an SSD does.

part of the reason for doing a open/DIY SSD would be to shame the manufacturers of the commercial ones into improving them.
creating a linux specific software only item won't do that (and because the hardware would then be linux-only it would be more expensive due to the limited production run)
it's also hard to test how a linux software solution would work for a windows or mac access pattern.
