There is quite a huge difference between the three new hard drives and the two others. Particularly the Quantum drive is very quick. Still Fujitsu and Maxtor are close behind, outperforming our reference drive, the IBM DTLA.
Data Transfer Performance
Both the Fujitsu and the Maxtor drive are able to beat the IBM DeskStar. The Fireball Plus AS from Quantum is pretty close behind it. If you want to use the drive for video applications or other streaming stuff, you should pay high attention to constant transfer rates. The Fujitsu loses less transfer speed than the others when reaching the end of the medium.
