- What are TBW (Terabytes Written) and DWPD (Device Writes Per Day)?Download Now. The endurance calculation can be expressed in two ways; TBW (terabytes written) represents the total amount of data that can be written to a storage device in absolute terms. DWPD expresses the same value as a ratio of the capacity over time. Imagine, for example a device with a five-year warranty. This equates to 1,825 days.
- Understanding SSD DWPD - Drive Writes Per Day - Kingston TechnologyDrive Writes Per Day (DWPD) calculations allow us to use the TBW specification of a drive to calculate the number of times the user capacity of a drive can be written per day over the warranty period (or a different number of years), based again upon the JEDEC workload used to specify the TBW. { {Footnote.N52105}}
- Enterprise SSD DWPD: Calculating in AdvanceDrive 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.
