--- Comment #96 from blaasdf <[email protected]> --- > What does "write amplification" mean? "Because flash memory must be erased before it can be rewritten, with much coarser granularity of the erase operation when compared to the write operation,[a] the process to perform these operations results in moving (or rewriting) user data and metadata more than once. Thus, rewriting some data requires an already-used-portion of flash to be read, updated, and written to a new location, together with initially erasing the new location if it was previously used at some point in time. Due to the way flash works, much larger portions of flash must be erased and rewritten than actually required by the amount of new data.
