DWPD/TBW CALCULATOR
DWPD Calculator
SSDs
are subject to wear during data writing, which significantly affects their
lifetime, which is one of the basic factors in business and server
applications. There are several parameters that determine the lifetime of
disks. Differences in their calculation can make it difficult to choose
the right drive.
Therefore, especially for you, we have prepared a calculator/converter
that allows you to compare the lifetime of disks, even when it is given in
different parameters. Just fill in the fields in the table below and press
the calculate button!

Explanation
Time Period - The average host-side write speed (MB / s)
required to reach the value.
DWPD or DW/D - (Drive Writes Per Day) is
the number of times the disk capacity can be written each day until the
warranty is void.
GB/day - number of gigabytes that can be written during
the day.
TBW - (Total Bytes Written) means the amount of data that
can be written on the SSD until the warranty expires, the value is given
in terabytes.
PBW - (Petabytes Written) means the amount of data that
can be written on the SSD until the warranty expires, the value is given
in petabytes.
For the disk capacity in GB given as S and the warranty period in years as
T the conversion between the different disk endurance specifications can
be calculated as follows:
- DWPD = GB/day ÷ S
- DWPD = (TBW(TB) × 1000) ÷ (S × T × 365)
- GB/day = DWPD × S
- GB/day = (TBW(TB) × 1000) ÷ (T × 365)
- TBW(TB) = (DWPD × S × T × 365) ÷ 1000
- TBW(TB) = (GB/dzień × T × 365) ÷ 1000
- PBW = TBW(PB) = TBW(TB) ÷ 1000
