If you diagnose your solid state hard drive after a while of usage using a special utility for this purpose (such as “ChkDsk” in Windows), you may observe the discovery of a few bad sectors on it. If it happens, must you think of a new replacement for this drive? Or is it something not worth your worry?
Actually if this case is with the traditional hard drive, then you must start to think of disposal and a new replacement, but with an SSD the case is a little different, as solid state hard drives are made out of flash memory chips and due to the nature of these chips it is not abnormal to have a small number of bad sectors on your flash-based SSD. Just rest assurred if the number of bad sectors remain constant and unchanged, otherwise if it keeps increasing it is a sign of the declinantion of the drive.
Bear in mind also that the respective firmware driver of the SSD helps a lot maintaining your drive from defection, and in this regard it keeps track of all bad sectors found and mark them as unusable, and that means even if the SSD contains some bad sectors, they will not be used and data is never written to them. That’s why you must always update your firmware driver to the latest version.
If you run Microsoft Windows OS and wish to keep track of bad sectors on your drive, run the “Check Disk” utility (short ChkDsk) then you will get a report of the number of bad sectors found. Afterwards, write down that number, then run that utility again after a few days to see if the number remains constant or it has changed.
If nothing changed, all is well. Otherwise it is the time of retirement of your SSD.
