Worried about losing valuable data due to sudden failure, do SSDs really last a long time?
Until a few years ago, many IT administrators and users were concerned about the risk of losing valuable data due to a sudden SSD failure. For this reason, it has taken SSD drive manufacturers a long time to convince the IT community that SSDs are safe when handling sensitive data.
A typical number for a 250 GB SSD
is 60 to 150 terabytes. This means that this writing performance is guaranteed. The so-called TBW number.
If you have a TWB of 100 on your SSD
you would have to write 240 GB daily over a period of one year, in other words, fill the entire SSD with new data every day, so that this value will be exceeded in a year! As a rule, this is never the case, because on average it is ~ 40 GB per day that the average writes.
You can find the TWB value in the data sheet of your SSD!
Samsung states that its Samsung SSD 850 Pro
with a capacity of 128 GB, 256 GB, 512 or 1 TB is designed for processing 150 terabytes (TBW), which would correspond to a daily read or write load of 40 GB over a ten-year period.
Samsung even promises that the product will withstand up to 600 terabytes of writing (TBW).
