Testing The WD Scorpio Blue

The Testbed

Testing Methodology

Testing Methodology

We tested in both Windows 7 and Windows Vista, with the latest updates. We chose to use IO Meter 1.1.0 RC1 as well as our "old faithful", WinBench 99 2.0, with the following tests :

• Platter Data Transfer Profile
• Business Disk WinMark 99
• High-End Disk WinMark 99
• Disk Transfer Rate (Beginning)
• Disk Transfer Rate (End)

Business Disk WinMark 99 is a real-world simulation based on three office application suites - Microsoft Office 97, Lotus SmartSuite and Corel WordPerfect Suite 8, as well as a web browser, Netscape Navigator. They are quite dated, but should still reflect the usage patterns of users in an office environment using such applications. The test runs through a script that keeps multiple applications open, while it performs tasks that switches between those applications and Netscape Navigator. The result is the average transfer rate during the script run.

High-End Disk WinMark 99 is a real-world simulation based on AVS/Express 3.4, FrontPage 98, MicroStation SE, Photoshop 4.0, Premiere 4.2, Sound Forge 4.0 and Visual C++ 5.0. However, it differs by running the applications serially, instead of simultaneously. There are individual results for each application but in this comparison, we will be looking only at the weighted average score, which is the average transfer rate during the tests.

Unfortunately, WinBench 99 seemed to have some issues with Windows Vista, or the current Vista driver for the SATA controller. It would register a SetFilePointer error in the Disk Access Time test. So, we were not able to obtain any Disk Access Time results.

Maximum Surface Temperature

We monitored the surface temperature of six hard disk drives during their benchmarks. The following chart shows their operating temperature range, from idle to maximum load. Please note that instead of giving you the absolute numbers, we are showing the temperature delta, which is the difference between the actual temperature and the ambient room temperature.

The WD Scorpio Blue may spin at just 5400 RPM, but it actually runs almost as hot as the 750 GB Western Digital Scorpio Black which spins at 7200 RPM. The difference was just 0.2 °C at full load and 0.4 °C when it's idle, but what matters is that it runs hotter in spite of its slower spindle speed.
