Calculating SSD DWPD is essential. And sure, you can calculate how much data you can write and still be within the vendor’s warranty, but how do you determine in advance before you buy the SSDs how much data you are going to write a day? First, a some background on Enterprise SSD DWPD. Drive writes per day (DWPD) means how many times you can completely rewrite all the data on your SSDs within a 24-hour period. All enterprise and most consumer SSD vendors I could find online give specifications for how many DWPD can be done on their SSDs, or the drive endurance in GB. Either way, you can calculate how much data you can write and still be within the vendor’s warranty, but how do you determine in advance before you buy the SSDs how much data you are going to write a day?
