hi guys,

each "platters" max:500GB ?
in market, 500GB one platter found ?
and more than one platters that price is cheap? only ONE platter that price expensive?

I think that platter density is already at 600GB per platter. One example is Seagate's 3TB FreeAgent GoFlex external drive.
According to this review ...
http://www.crunchgear.com/2010/07/01/ha ... ard-drive/... the drive is a 7200 RPM, 3TB, Barracuda XT, model ST33000651AS. The "5" in the model number suggests that it has five 600GB platters.
Here is a close-up of the label:
http://www.crunchgear.com/wp-content/up ... -3tb-2.jpgThere are other drives that have a bit density per track that is consistent with a 600GB platter, but they are limited to 500GB per platter. You can see this in the maximum sustained data transfer rates. A 500GB density results in a performance score of ~130MB/s, whereas a drive with a 600GB density would score between 140 and 145 MB/s.

640GB/platter discs will be out soon/have just started releasing.
