2TB external portable drive (2.5")

[#1]

Whilst industry-standard portable external drives in the 2.5" form factor typically have either 2 or 3 platters, is there any reason why there could not be an external drive with 4 platters?

It would presumably be 15.5mm thick (drive without the cover) rather than the current 12.5mm for a 3-platter drive, but it would crank up maximum capacity to 2TB, based on 4x500GB platters. I work in media and the bigger the disk, the better it is. However I can't lug the 3.5" disks which are way too heavy and unwieldy with their power supplies.

So a 2.5" solution would be ideal, and I believe there would be a market for it particularly among people working in media (movies, digital photography, music etc.) who require tons of data space.

Yes definitely waiting for 2TB.

Western Digital is already late on 1.5TB which is proposed by every other manufacturer, I wish they could take they lead on 2TB portable hard drive. I feel the development of portable hard drive is somewhat superslow.

However I hope they keep it slick especially now that the Macbook Air and PC ultrabook are becoming the standard for laptops (plus now there is a new market segement with ultrathin hard drive).
