I'm not sure about the flash used in the wemos, but many flash chips do wear leveling where they rotate the blocks used to store data, helping it wear out more evenly.

There might be another factor in that the spiffs filesystem has its own data structure which would potentially add further writes each time.

With the amount of data you're writing though you're talking thousands of years before you wear it out, so probably don't worry too much.
