4. About write endurance
SSD has write endurance which limits the number of times each memory may be written,
due to the characteristic of the memory that is used. Write endurance can be calculated
by the following formula as a reference value:
The write endurance of SSD is determined with the total capacity.
Life expectancy can be calculated by the number of writing per day.
The number of writing into drive per day (DWPD) =
SSD’s TBW(TB) x 1000
365 days x years x SSD user capacity
The actual TBW is determined by the free space (available space for user).
If the SSD has 128GB capacity and TBW = 80TB, and the user available space (rewrite area)
is 1/2 size, the expected life can be calculated with an assumption that TBW is half of 40TB.
When the 4MB file of 128GB capacity and TBW = 80TB, user available space (rewrite area)
is 2/3 size is made, and rewrites once per 10 seconds.
Writing size per day = 4 x 6 x 60 x 24 = 34.56GB
Write endurance = 80(TB) x 2/3 x 1000 / 34.56(GB) / 365 ≈ 4.3(years)
These are reference values. Confirm its longevity by the following S.M.A.R.T. after installing
the specific software (*) and implement tentative writing.
Life expectancy can be obtained by installing the self- diagnosis program that acquires
S.M.A.R.T. information of SSD.
