The best practice is to not use swap if you use a flashdrive.
Even the newest flash generation will fail early if it gets written to too
Each block of NAND flash can be rewritten up to a million times.
This may seem to be a lot until you start doing your figures.
It is the most frequently changed block that will cause the drive to fail,
and that will be in the file system structures.
Even with the best case scenario, the drive will wear out within two years.
