Crystal Disk Info shows two distinct values for Total Host Writes on my SSD when hovering over it, one of which is less than the other; which number of writes is correct? Sreenshot

    Well 1472 divided by 1024 does equal to 1.438 :) Commented May 31, 2022 at 11:42

It is the same number. If you look carefully the result is 1472 GB and in the pop-up is 1.438 TB, where according to the binary convention 1024 gigabytes equals 1 terabyte.


1472 / 1024 = 1.4375 TB

You can find a more detailed post about the metrics here .


Edit: It's not drive capacity but total bytes written.

It show the capacity of your drive in different binary format (in this case 1472 GiB 'GibiByte' and 1.438 TiB 'TebiByte').

For anyone looking to quickly convert between different format, just google

[NumberToConvert] [format in binary] to [format to convert to in binary]

ex: 1472 GiB to TiB => 1.4375 TiB

Make sure the dropdowns below the number are in the correct format too (Gibibyte and Tebibyte respectively. See screenshot below).

***I think Windows always display drive capacity in binary format while most drive manufacturers use decimal format in their ads. To convert from binary to decimal and viceversa, google as 1472 GiB to GB (GB stands for 'GigaByte')

  • That's not capacity, it's total bytes written. Since a byte can be overwritten many times, it can be bigger than the drive size. (In this case 512.1 GB). But yes, it's using binary for those write-endurance numbers. Commented Jun 1, 2022 at 15:39
  • Sorry, must have misread it at first sight.
