Hard disks by far are the slowest part of the computer today when it comes to the mechanical nature of them; granted, DVD drives are slower still, but they aren't used for storing the Operating System or Virtual Memory which the hard disk plays the important role with. The slower the drive, the slower your OS load times will be along with application lag due to wait states for the HDD to get off its butt and start working.
The Seagate Company has pushed forward in producing HDD's that not only run at the fastest possible speeds for their generation, but have high capacities along with a good dollar value as well. Seagate has now got a drive that can not only rival the Raptor 150 drive, but it is even more advanced with higher cache sizes and can operate at a lower RPM; this results in less heat and also costs less to produce. The days of the Raptor are numbered with this drive entering the market, and it's nice to see an affordable option with high capacities available.
Overall, the 7200.11 is TweakTown's Must Have HDD for all the right reasons.
