Thats awesome!
The SATA connection on the rear says it all for this little marvel. Give it 5-10 years, and we'll have Terabyte versions of these babies, perhaps marginally bigger, multi layers of chips.
Then kiss goodbye to the troublesome, power hungry spinning disk horrors that began life as the winchester drive (disclaimer: possibly not historically accurate).
Think about what it'll mean to PC form factors in general - no longer will we need 3.5inch drive cages.
The normal USB based SSDs will likely also spell the end for optical formats too, so no longer will we be needing the 5.25inch cages either.
I know small form factor/mobile machines have been around for donkeys, but this could truly mark the beginning of a complete exodus from olde form factoring.
Very cool, a great move there Samsung.
