Buffalo is going to release the world’s slimmest portable hard disk in the beginning of February. It’s a 500GB hard disk that is only 8.8mm thick and weights 140g. Its surface has been treated with aluminum, with a smooth texture and great strength that is relatively scratch-proof. It is very easy to slip in your pocket and carry around.

Also, I found it very handy that it has three modes, depending on your needs:
“Speed Mode” – Quad-speed
“Save Mode” – can save 1.2 times as big data as usual by automatically compressing files when transferring them.
“Balance Mode” – can automatically switch between Speed Mode and Save Mode depending on a file.

Retail price is ¥11,655 including tax.
