AFAIK, flashdrives operates the same as ssd's.
while SSD's and pricey flashdrive (e.g. Sandisk Extreme) support the trim
command to erase occupied space the sheaper flashdrives do not support trim,
what means they get slower over time.

Writing to flash has more to do with how the flash firmware works. To
write to flash a full block needs to be erased and then you can write
to it. Some firmware/devices keep free already zero'ed blocks and
those can be written to fast but once those run out then it has to
erase before writes.
