The ESP module have an onboard Flash for the firmware.
What is your question exactly ? Do you mean that you wish to attach a external SDCard or an external USB drive ?
(SDCard is easy, but USB drive would be difficult since there is no USB on ESP)

This means having another MCU with USB in Host mode, and having a protocol between both MCUs.
Maybe you can take a look at those links :
