However, even with all the effort and features that Swissbit applies to the drives, at some point in time the last spare block is consumed and the drive experiences the end of life. Swissbit makes sure that even at this point the data can still be read, which is not standard in the market. External tests have shown that lots of drives cannot be accessed once they reach the end of life. The user does not want to lose the valuable data that has been collected over the operating period. For an even safer scheduled replacement of the drive, it is mandatory to have a good predictability of the remaining life. The Swissbit Life Time monitor can access the utilization data and predict how long the drive can continue to work in the same environment.
