PCMark05 is an application-based benchmarks and a premium tool for measuring overall PC performance. It uses portions of real applications instead of including very large applications or using specifically created code. This allows PCMark05 to be a smaller installation as well as to report very accurate results. As far as possible, PCMark05 uses public domain applications whose source code can be freely examined by any user.

PCMark05 includes 4 categorized suites for benchmarking your computer. These include CPU, Graphics, Memory and a Hard Disk Drive benchmark. In our case, we selected only the Hard Disk Drive benchmark.

The NexStar 3 (eSATA) earned the most PCMarks, while the motherboard's SATA follows closely behind.

The test results, more analytically:

On the following pages, we will compare the transfer speeds between the eSATA and USB 2.0.
