Hard Disk Drive Performance Comparison Guide
Hard disk drives, also known as hard drives or simply HDDs, are critical components of every computer. Although flash-based SSDs (solid state drives) are making some inroads, the ubiquitous hard disk drive is still the ultimate storage choice for most users. Hard disk drives provide a large amount of data storage at low cost. Perfect for storing bloated software and all sorts of "interesting stuff" that we download from the Internet. 
Of course, the hard disk drive is more than just a repository for our data, or a place to store the games we play. It affects the performance of our PCs, especially how long it takes to launch applications or games, or open up files. Its performance is also critical if you are low on RAM because your PC will use more virtual memory. This is where the Hard Disk Drive Performance Comparison Guide comes in.
In this article, we will be comparing the performance of all the hard disk drives we can get our hands on. This would be similar to our Intel Core 2 Processor Performance Comparison Guide. It may start off small, but we intend to keep adding new hard disk drives and even new benchmarks as we go along. Let's take a look at the hard disk drives we have rounded up for this comparison.
