The Best Internal Terabyte Hard Drives

Page content

How this guide works

This guide will list the top four internal 1TB internal hard drives for a desktop PC. If you’re familiar with my previous guides, there is no particular order in which these hard drives are listed. Of course, you may notice that the list is a little bit light. The reason for that being that there are only a few manufacturers at the moment who produce internal 1TB drives.

Seagate Barracuda 7200.11


  • 5 year warranty
  • Easy to install
  • 32MB buffer
  • Rapid data-access time; one of the fastest around

  • Virus scanning on the disk takes a little longer in comparison to other 1TB drives

Western Digital Caviar GreenPower

Costs roughly: $245


  • 3 year warranty
  • Designed to consume less power but without sacrificing productivity


  • Buffer is only 16MB. It’s not bad, but the Seagate drive contains double by comparison
