The Lexar P20 was an experiment in selling an SSD in a "normal" flash drive form factor. 400MB/s thorouput on a usb3 port. I used mine as an OS install drive and Windows 7 would install in seconds. Crazy fast and quite hot running.
That drive was discontinued as they would cook themselves and capacity was low for the price.
I wonder what sort of prices these will hit the market at. That seems to be the deciding factor in whether they sell well or not.
