Next part is fio sample config files for Windows, here is sample config

random_distribution=zipf:1.3

Few Notes:

• Update the field “directory=” with correct primary volume drive letter(required only if it is not already H: )
• Update the field runtime for increasing or decreasing the time of run in seconds.
• Update the field zipf to 1.1 or 1.2, if you want the locality to spread.
