Portable HD Tune

Portable HD Tune is a software that allows you to view information on your hard disk.

Since this is a portable product, the program doesn't require any installation, so you can place Portable HD Tune on any external device and directly run in on any computer. It also means that it will not affect your Windows registry keys in any way.

The interface of the program consists of a simple window (that cannot be maximized). Here, you can view information on each drive, including its temperature.

You can benchmark your drives and find out minimum, maximum and average transfer rates, as well as access time, burst rate and CPU usage, while viewing a graphical representation of the drive's activity.

In the "Info" tab, you can check out the label, capacity, usage, type and bootable status of each partition. Supported features include "Read Look-Ahead", "Write Cache", "Host Protected Area", "Device Configuration Overlay", "Security Mode", "Power Management", "Native Command Queuing", and more.

You can view the health status on your drive, according to the S.M.A.R.T. data (e.g. power on time), and you can also perform an error scan and view results in a graphical representation.

You can copy information or a screenshot to the clipboard, save the screenshot as PNG, or configure options (e.g. adjust the test speed and accuracy of the benchmark's transfer rate and select block size, set the temperature unit and color).

The program uses a low amount of system resources but doesn't have a help file, unfortunately. This may mean that beginners would have a hard time understanding the technical details behind HD Tune. Otherwise, the application does a very good job at displaying accurate information on your drives.
