HD Tach - A physical performance test hard disk

HD Tach is a test of physical hard disk performance that uses a special kernel mode VXD to get maximum accuracy by bypassing the file system. A similar mechanism is used in Windows NT/2000.

The proof of HD Tach sequential read is a bit different from other benchmarks. Most benchmarks create a file on your hard drive and test within that file.

The problem is that modern hard drives use a zone bit recording technique that allows different read speeds depending on where data is located. Data on the exterior of the unit is much faster than data recorded on the inside.

HD Tach reads from areas all over the hard drive and reports an average speed. It also records the speed of reading a text file that can be loaded into a spreadsheet and graph to visually read test results.

In addition to sequential read, HD Tach tests the drive time random access. Random access is the true measure of search speed. Many drives advertise sub 10 millisecond seek speeds, but seek speeds are misleading.

Finally, HD Tach tests the drive burst speed. The burst speed is the speed that data can be accessed from on-board unit memory read-ahead. This measures the speed of the drive controller and interface.

The commercial version of HD Tach gives you access to all functionality, ease of use and reliable benchmarking you expect from HD Tach. We also added the ability to save graphics benchmark results and saved benchmark results with previous results or results of the new database, including the unit.

We have created this database of benchmark results submitted by our users through the "Upload" from the new HD Tach - after running the test is given the option of sending their bearings in the drive to Simpli Software inclusion in our database.

Limitations:

· The commercial software version can also be used for up to 14 days for commercial users as an evaluation, as indicated in the license agreement.
What's New in This Release: [read full changelog]

Support for Windows 2000 and Windows XP. We will evaluate the need to support Windows 9x/Me permanently.
Built on the basis of data on the drive so you can compare the benchmark units and keep their bearings in the database.
Internet helps you download updates to the reference library of our website.
Button "Upload" to upload their results refer to our website. We encourage you to use the 'Upload' button and the database will be the main users supported. We would have reference points 04/03 of each unit before submitting it to our database a "reality" check.
Zoom / Pan feature in the graphics. Draw a box with the left mouse button from left to right to extend, right to left to unzoom. Right click and drag to move around the graph.
* Support for fast and long term readings.
· We believe all benchmarks to be exact. CPU benchmark now uses the Windows internal counter for CPU usage and should be much better in the new processors.
