It's just technical stuff to do with the orientation of the magnetic particles which store the data, I have no idea why they advertise it to the average consumer, perhaps they think it sounds impressive. IMO it just causes confusion - people think they have to have the drive mounted on it's side. Basically, to you, it means 'big and fast'

Not sure what an average consumer is. A consumer who is into changing hard drives should know what it is. It is, as was said, the orientation of the mag particles in the media - and the result is more storage area per platter.

Example - laptop hard drives max'd out at 120 GB with normal particle orientation, but then Seagate released a PR model with 160 GB, and they will soon release a 200 GB 2.5" drive.

Anyway - I have two of them (160s) for my laptop, and they are great.

Getting nearly twice the storage from basically the same drive at nearly the same cost and w/o software compression IS impressive to me. Not to mention the extra sequential read speed you pick up as a natural consequence of twice the data per track.
