The lifespan of an SSD is generally measured by the following three indicators:

MTBF: Mean Time Between Failures (MTBF), which is a reliability or failure rate quantification metric used to estimate the durability of SSDs. In simple terms, it is the time interval between two failure points, expressed in hours.

TBW (Terabytes Written): It refers to the total amount of data that can be written to the SSD before the end of its service life for a specified workload.

DWPD(Drive Writes Per Day): The number of years an SSD can operate normally with a certain number of full drives or a set number of full drives written per day.

How to check the lifespan of an SSD?

If you are concerned about excessive SSD usage, you can check the total bytes written (TBW) to estimate the remaining SSD usage time. You can use CrystalDiskInfo software to view the total host writes and compare them with the provided TBW values after conversion.
