Testing Methodology
We tested in both Windows 7 and Windows Vista, with the latest updates. We chose to use IO Meter 2008 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 is not fully compatible with Microsoft Windows 7, registering a SetFilePointer error in the Disk Access Time test. So, we were not able to obtain any Disk Access Time results.
In addition, it would keep crashing if the hard drive was tested with a single partition. This is likely due to a limit on the size of the partition that is supported by WinBench 99. We came up with a workaround by dividing the hard disk drive into 5 partitions of equal sizes. We then tested each partition individually and averaged the results.
Maximum Surface Temperature
We monitored the surface temperature of seven 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 Western Digital RE (WD4000FYYZ) is a rather hot drive, with a maximum surface temperature that was almost 13 °C above the ambient temperature when it's busy reading or writing. The drive is about 4 °C cooler when it idles. Still, its idle temperature of 9 °C above ambient temperature is 2 °C hotter than the 2 TB Western Digital RE4-GP running at full load!
If you live in a country with a high daytime temperature of about 32 °C, that would mean the 4 TB Western Digital RE's surface temperature would vary between 41 to 45 °C, depending on the load. Of course, this drive is really designed for enterprise use, in air-conditioned servers. If you intend to use this in your home setup or an office workstation, it would be a good idea to keep it cooled.
