chriszzz said:1.This is basically a USB-On-The-Go harddisk casing. You can get a similar drive from http://www.kenarservices.com/2002080100.htm (in Bugis, Midlink Plaza) for around $60.
2. You should be able to use a standard 5V adaptor, eg, those that comes with your USB hub. Those provide 1 A current, which is plenty for a portable harddisk.
3. I would still recommend an XDrive or equivalent instead. The LCD displays the amount of space left, and if any errors occurred during the copy. Much more reliable, and works as a card reader too. The latest models are very small and compact, and uses standard digicam batteries. Both adaptors and batteries are included, so there's no extra cost. Besides, companies like Vosonic ( makers of XDrive ) regularly provides firmware updates, which is non-existent for these no-name HDD casings.
Any idea how much does the XDrive costs for different capacities?
