As we have seen, a potential drawback of SSDs is that the underlying flash memory can wear out. For example, for the SSD in (Figure 1), Intel guarantees about 128 petabytes (128×1015128×1015 bytes) of writes before the drive wears out. Given this assumption, estimate the lifetime (in years) of this SSD for the following workloads: Average case: The SSD is written to at a rate of 20 GB/dayGB/day (the average daily write rate assumed by some computer manufacturers in their mobile computer workload simulations). Express your answer as an integer in years.
