HD Tach has been around for a long time and is excellent when it comes to testing hard drive performance. It is also a very handy program when it comes to testing the controller used on particular motherboards. Tests such as Read, CPU Utilization and Burst are available at a click of the button and give you a good idea of how the hard drive can perform from system to system.
Here we see the performance across the drive. For the most part the data flow is linear across the drive, but there are some dips in performance; the most noticeable is with the write speeds where performance drops as low as 12MB/s.
