Sun CEO Jonathan Schwartz has an interesting blog entry about how Sun Microsystems will start introducing Nand Flash with ZFS as an enterprise storage solution by the end of this year. With the price of Flash memory already plummeting this could be an economical alternative to the expensive NAS solutions.

I still think he shouldn't have mentioned HDDs and RAM in the same breath. It's more than just a little misleading since the amount of energy needed to keep the information differs by many orders of magnitude.
Actually, I think he was alluding to the fact that you have to spin up a HDD in order to read data from it and that requires energy. I don't work in a datacenter but I'd imagine they keep the platters spinning 24/7 to guarantee low latency and avoid wearing out the drives too fast. IIRC, a spin up/spin down is far more harmful to a HDD than running continuously.
