pretty sure the 300 is 3 platters I bought one today, I quick formated and did a quick hdtach which was pretty weak. burst 131.9, read average 52.5 seek 15ms on ich5r. It's a new drive since it says the warrenty is till jan 31 2010. My friend bought a 250 not sure what he tested it on but it got 120.1 burst , 56.9 read, but a high 16.9 seek. Let you know later proper long benches. I might try and exchange this anb buy 2x250's
According to an Email from Seagate the 250Gb is 2 platters, 4 heads
Having now installed the drives & testing with HDtach 3, I have obtained the follwing results on both drives ( avarage of the 2 ) :
Controler used is Via VT8237
Burst speed = 124 Mbs, Randam access = 15.2ms, Avarage read = 55mb
It does appear that they are 2 platters.
Very much quieter than my Diamondmax 10 300gb drives & feel just as quick in
