well just to mention a little about this.
i'm currently in Shanghai on attachment and the shop here sell the case for only 380 RMB which is a steal (less than 80 sing).
The internal 2.5" Hdd can buy any type you like.
Do you guys think it's worth to buy?
The case is the same size as a normal external 2.5" Hdd and there's slots for all the different cards.
While not using as a portable storage, it can be simply be use as a external Hdd. It's not using batteries but instead use those rechargeable gum batteries.
