I’ve seen several articles and blog posts about solid state drives (SSD) over the last few weeks. Solid state drives use non-volatile flash memory for storage (Wikipedia article). There are many benefits to using them, including radically faster boot times and greater durability (because they have no moving parts).
Engadget has a recent post about the future of pricing for this technology. Unfortunately, though we’ll see a rapid drop in price over the next year or two, pricing does not appear to come in line with the cost of traditional hard drives anytime soon. The gap looks like it will not go below 3x the price per gigabyte of traditional hard drives even by 2010.
