Can a single post make you smarter? This was an awesome description of why log file systems match with SSD (as long as TRIM is part of the picture). It also covers how flash based memories work in practice (small reads, but block writes).<p>Very fascinating stuff for a guy that only does simulations software, but was once super curious about electronics in junior lab physics (nand gates, opamps, feedback circuits).<p>Great SSD video (the 24 raid 0 setup)

A reckon a battery backed RAM/SDD hybrid would be the fastest option available. I did search and found a 4G one that was selling for thousands of dollars (can't find the link now). They said that it could back up the whole of RAM to SSD in 60 seconds so the data security (with a reliable battery) would be pretty good. Should scale as well with the same amount of time required for more lots of 4G. I can't see any reason why this should have to cost so much though. 4G SSD + 4G RAM + Battery + Controller < thousands of dollars. Must still be in the 'paying for the innovation' stage I guess.
