How do you back up the disks?

Where exactly can I buy cheap 3TB+ WD internal & external hard disks at Thailand? How much are they usually?

• My father is visiting Thailand soon. With the Thailand flood causing all the hard disks in the world to be really expensive, I was wondering if Thailand sells WD hard disks cheaper compared to what it is now in most parts of the world. I plan to buy at least four 3TB internal WD hard disks (Caviar Green so that they are power savers and silent) and one 3TB external WD hard disk (preferably WD elements or any WD that can stack flat & harder to knock over). I mostly will use the internal hard disks to build a NAS. Would it be alright to ask where exactly you can buy in Thailand and how exactly to get to those places? Are they by chance cheaper? How much would those hard disks cost? Thank you in advance :)

• Answer:

  I don't think they will be cheaper. It's like buying an iPhone in China. If a Foxconn worker wanted to buy one of the phones he made, it would cost him at least 4x the price of in the US. You should try buying a large external hard drive and taking the internal drive out of it.
