The new TDK hard drive replacements are constructed of flash memory and are completely solid state technology. The one shown at right is 32 GB. These things are going to revolutionize the industry for a few reasons. First, they will be really fast, maybe 1000 times faster than hard drive access. Second, with no moving parts, they should last darn near forever, and that's as green as the motherboard it's printed on. No word on the cost of these puppies yet.
