CrystalDiskInfo is a software that lets you view information on your hard drive and some external drives.

You should pay attention when installing this product. Since it is ad-supported, the program offers to download and install third-party software that it doesn't need to fully function.

Once you initiate the application, CrystalDiskInfo automatically displays a list of details on your hard drive.

The user interface of the program is standard, but novice users would probably have a hard time understanding the information displayed here.

You can view the drive model name and disk size, firmware, serial number, interface type, transfer mode, drive letter, buffer size, NV cache size, rotation rate, power on count and on hours, and more.

Furthermore, you can view the health status and temperature of the drive, as well as S.M.A.R.T. information (e.g. "Read Error Rate", "Spin-Up Time", "Start/Stop Count", "Seek Error Rate", "End-to-End Error"), such as current, worst, threshold and raw values.

In addition, you can access "Disk Management" to create a simple partition (basic, spanned or stripped), configure disk conversion options, as well as extend and shrink partitions. But you can also open the Windows Device Manager, set CrystalDiskInfo to automatically run at startup, enable advanced disk search, select your preferred language, change the font, and more.

The application uses a low amount of system resources. It comes with a help file that could have better explained the features but didn't cause us any problems during our tests. We mainly recommend CrystalDiskInfo to power users.
