I used this stie recently myself: http://rml527.blogspot.com/2010/09/hdd-platter-capacity-database.html
Yeah, I believe Seagate did that with some of their current 7200.14 drives as well. Not all of them use 1TB platters... even within the same size.Originally Posted by CynicalUnicorn
Other than power (which is difficult to find for not-processor components anyway), that is exactly what I needed. Interesting, not only is one of Seagate 2 TB drives either two or three platters depending on which model (with the EXACT SAME MODEL NUMBER) you get, so are the 2 TB WD Greens and Reds (again, the only difference is weight, nothing else to identify it). I'll be sure to stay away from those and go straight for 3 TB. Also confirms for me that my laptop HDD is in fact two 500 GB platters, which is less mass to move, which should put less strain on the motor and therefore battery.
