If anyone is interested in a talk on SSDs, chime in. I can present my
experiences with these devices. I've evaluated the performance of
several vendors' products, ranging from the poor to the exemplary. I
can talk about the modifications made in the block layer to accommodate
for these devices, and the current implementation of the block discard
support (which maps to ATA TRIM, which is important for device lognevity
and performance) and how that is wired up to file systems such as ext4.
Cheers,
Jeff
