Testing The Hard Drives

The Testbed

Testing Methodology

We tested in Windows 7 and Windows Vista, with the latest updates. We chose to use our "old faithful" benchmarks, IO Meter 2008 and WinBench 99 2.0, with the following tests :

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

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.

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 drive into several partitions of equal sizes. We tested each partition individually and averaged the results.
