The next big thing, though I've been hearing about them for a little while. They are silent, use much less electricity, produce much less heat, and perform very very well compared to any hard drive. Perfect for notebooks, etc. The final piece in my quest for a silent rig.
Only problem is that they are really expensive and it will take a while for prices to come down.
The other drive, that I'm interested in, is that samsung hybrid drive that is supposed to use ram for quick access and their silent hd for storage. It should be a nice option for price, performance, and silence if it ever makes it here. Though, Hybrid drives might never make it to market if prices come down enough on those ram drives.
Anyone get to play with one yet?
