The data stored in hard drive is almost always important (also vital for few guys), so it’s necessary to regularly check their health status. CrystalDiskInfo is an open-source, free hard disk detection tool from Japan. It can provide comprehensive health info of HDD/SSD through reading its S.M.A.R.T. data (which can be used to monitor and analyze the health condition of hard drive in real time).
Just open it, then you can quickly read the detailed information (all kinds of technical indicators, especially health related) about the hard disk on your machine. This includes interface type, rotation speed, current temperature, service time, transfer mode, hardware serial number, buffer size, etc. Again, CrystalDiskInfo makes a general evaluation about your HDD/SSD according to the S.M.A.R.T. scores. And especially, it can raise an alarm when your hard drive is almost broken – it does make big sense to nip in the bud.

One thing to note is that such kind of information is for reference only, and that does not completely represent the real health status of your HDD/SSD.
