Just sharing my opinion, so no hate please. :) I voted for MX100's because I personally don't think that samsung will drop their prices that much.
Also, Tiger Direct is closing more than 200 stores I believe and they took off only 5% on Samsung SSD's. :/
I know the way this works, within a year I will be thinking why oh why didn't I buy a larger drive to begin with. So I think I will wait for a 500GB+ option and above...
Depends on how much you can save on this deal, prices on these drives usually are pretty steep. If you really need that much storage it might not be necessary to run it of an SSD.
