14 x 1000Gb Hard Drives Compared
 

First of all, we can name the fastest 1-terabyte drive in all our tests. It is the WD RE3 (WD1002FBYS). This is the best buy if you prefer maximum performance. But if you don’t like its high price, you can take the WD Caviar Black (WD1001FALS) which is somewhat slower but costs much less. The Hitachi Deskstar E7K1000 (HDE721010SLA330) is third in terms of sheer speed.

Then, we also wanted to see the effect of increased recording density and larger cache on HDDs’ performance. It is not easy to answer what is better, actually. Taking the three drives from Western Digital’s Green Power series, we can see that it’s better to have both: the WD10EADS with higher-density platters and maximum cache is the fastest of them.
