Because SSD drive health is based on different metrics than tradtional driv health, different data points are emphasized. In the screenshot below, however, you can see the same CrystalDiskInfo S.M.A.R.T readout for a Western Digital SSD. You’ll notice that there is no data points for total data reads/writes because that isn’t a metric used to gauge HDD health. If your drive health is “Bad,” you should approach data backup with a delicate touch (check out the section below about what to do if your drive is dying for a more detailed look).Īt the top of the window interface, you can also check the drive temperature and see stats about the drive, like power on count, power on hours, and more.ĭo note, when looking at the screenshot above, that the drive shown there is a mechanical hard drive, a Western Digital 14TB media storage drive. If your drive health is flagged with “Caution,” you should back up your data and make plans to replace the drive. The general health status is indicated by blue for “Good,” yellow for “Caution,” and red for “Bad.” If your drive health is good, there isn’t much to do beyond check out other stats because you’re curious. There are two layers to using CrystalDiskInfo, simply running it and getting a “Yup, everything looks good” feel for things by checking the general “Health Status” of each drive, or by digging into the individual S.M.A.R.T. Conduct a One Time Test with CrystalDiskInfo The application is available as a portable app or with an installer. attributes for mechanical hard drives (HDD), solid-state drives (SSD), and Non-Volatile Memory Express (NVMe) drives. Status with CrystalDiskInfoĬrystalDiskInfo is a free easy-to-use open-source Windows application that will show you S.M.A.R.T. The health of your SDD is almost entirely a reflection of how much data has been written to the solid-state memory inside it.Ĭheck S.M.AR.T. Unlike mechanical hard drives that tend to die from physical wear and tear, SSDs and NVMe drives-barring a blown electrical component or something catastrophic-die from eventually exceeding their Terabytes Written (TBW) rating. SSD drive health (including NVMe drives, which also use solid-state memory) is almost entirely focused on lifetime read/write data. tests for mechanical hard drives include data points for things related to the moving parts of the drive and the effect of motion on them (number of times the drive has spun up, failed to spin up, experienced shock or sudden stoppage, and so on). tests on different types of drives is what the tests measure. The biggest thing to remember when running S.M.A.R.T. In fact, while you can deep dive into the individual attributes if you’re so inclined, you don’t need to do so to use the tools and get actionable feedback on the health of your SSD or old HDD. attributes is a bit geeky and the output is a bit arcane, but fortunately, there are tools that make it easy to check the data and interpret it. Checking a hard drive or SSD’s S.M.A.R.T.
