Samsung Magician provides detailed information about SSD status, such as Total Bytes Written (TBW) information, cache usage time, and additional information about the SSD product and system. With Samsung Magician, users can diagnose the health of the SSD, update new firmware, and benchmark for optimum performance.
10 TBW/day ÷ (8 total cache drives) = approx. 1.25 TBW/day per drive Interesting! Less than 4 TBW/day! Unfortunately, this is flawed math because it does not account for write amplification. Write amplification is when one write (at the user or application layer) becomes multiple writes (at the physical device layer).
The TBW is a measure of data the drive can write over its lifespan. For example, if an SSD has a 300 TBW rating, the drive can write 300 TB data before it needs replacement.
TBW indicates how many terabytes of data can be written over the SSD’s lifetime before it needs to be replaced, while DWPD is an endurance rating that tells users how often they can rewrite a specific number of gigabytes per day for a specific number of years before the SSD becomes unreliable.
