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).
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).
Great SSD video (the 24 raid 0 setup)

- glymor 17y agoValerie Aurora articles have gotten good reviews here before eg http://news.ycombinator.com/item?id=735982 http://news.ycombinator.com/item?id=735982 An SSD is already like a raid 0. This is a Samsung block diagram of what's going on inside http://www.pcper.com/images/reviews/766/SSD-Samsung.png http://www.pcper.com/images/reviews/766/SSD-Samsung.png
- ovi256 17y agoYou may want to get in electronics hacking ... Look at some of this stuff for inspiration : http://www.ladyada.net/make/ http://www.ladyada.net/make/ I prefer not to hack just for hacking's sake, but to build something I need. For example, ATM I'm looking into building a bedside alarm light - an alarm clock that wakes you up with light. I would love one. The commercial models are stupidly expensive (169$ for a nice Philips model [1]). The electronics are pretty easy to replicate, I'm having difficulty with the case. Philips did an awesome job with theirs - great design and build. Actually, most DIY electronics suffer from the same problem : cases suck, because we just do not have the means of extruding plastic and the such. Maybe 3D printers will help.
