http://www.anandtech.com/show/2738/3 is a typical trust-nothing tech
article, with those "let's just pretend you're not blocking ads"
keep-clicking-onward multi-page cliffhanger layouts, but it is an
interesting summary of why the fragmentation curve is so steep on SSDs,
and supports Linus's opinion you really shouldn't trust anybody but
I'd be interested to see this confirmed or refuted in a less irritating
BitKeeper, how quaint.
