    @KurtE Just got back from some errands. Can't see anything wrong from the pictures to be honest or it just could be my eyes. I just added and tested basically a complete wipe of the QSPI disk based on Frank's stuff...

    @KurtE Think we are cross-posting now with these edits? Check the benchmark sketch is configure for QSPI not Program. The sketch as posted is configured for Program. The results you are getting is what I am...
