How many years your SSD will last given its TBW and your writes.
Writing 50 GB a day, a 1 TB SSD rated at 600 TBW would take about 32.9 years to use up its guaranteed endurance. That is 18.25 TB a year and 0.05 full drive writes per day: for home use TBW is rarely the limit.
Works out how many years it would take to use up the endurance (TBW) the maker guarantees. Most SSDs are retired for other reasons long before reaching that limit.
years = TBW × 1000 / (GB per day × 365); DWPD = GB per day / (capacity × 1000)Works out how many years it would take to use up the endurance (TBW) the maker guarantees. Most SSDs are retired for other reasons long before reaching that limit.
All amounts use the same currency of your choice. These are estimates, not measurements or offers.
Check whether an SSD will cope with your use before buying it, or how much life is left in the one you have. TBW is on the maker spec sheet, and daily writes can be read with tools such as CrystalDiskInfo, which show total data written: divide it by the days in use.
If the result exceeds the life you expect from the computer, TBW is not a limit and you can choose the SSD on price, speed or warranty. If it comes out under 5 years, as with database servers or heavy video editing, look for models with higher TBW or enterprise drives. The warranty usually ends when the TBW or the stated years are reached, whichever comes first.
It usually keeps working for a while, but the warranty ends and the risk of errors grows. Watch its SMART status and keep a backup.
On Windows, CrystalDiskInfo shows total host writes; on Linux, smartctl -a. Divide that total by the days in use to get the daily average.
Drive writes per day. A DWPD of 0.3 on a 1 TB SSD means 300 GB a day for the whole warranty period.
