CrystalDiskInfo is a neat and handy utility that helps you keep an eye on vital parameters of your hard disk and timely acknowledge any potential problems. Since preventing it is always a better choice than having to deal with the consequences of a disk crash, this tool can help you save precious data that could be otherwise lost in case of an unwanted event such as the aforementioned disk crash.

As long as the disk supports the S.M.A.R.T. technology, CrystalDiskInfo can monitor that disk, regardless if it’s a SSD or a classical HDD one. It even supports some models of external USB disks. By monitoring the S.M.A.R.T. attributes this application can actually track the most relevant parameters that indicate the health status of the disk. For example, it can accurately monitor its temperature.

A big plus is represented, in my opinion, by the effective alerting features. Whenever a monitored disk parameter reaches a critical threshold, as it has been previously configured, the application can announce you in various ways: by sending mails, emitting sounds or both.

This tool is also pretty neat, simple, and intuitive. Its interface is straightforward and easy-to-use though it includes access to advanced features which aren’t sufficiently explained in order to make them suitable for being used by beginners as well. The help file, which is available only online in the form of a manual, is also a bit shallow. Other than that, this tool is neat, handy and works like a charm. There’s also a Shizuku edition – Shizuku being the name of a Japanese cute girl that watches over your HDD and SSD. My personal verdict is that you may rely on this tool for your disk monitoring needs, especially if you don’t feel like you need much help in order to use it.
