# In short script check Alloc-Free for crypto counters which will be very low for working cards - usually less then 100 or more around 10.
# Note threshold is set to 3000, in some corener cases during very high load may go to this value, but will go back in second back to low value. 
# BUT, if you see 4 lines: Issue deteceted delta for same card then it is 100% crypto chip issue.
# This threshold is assumed as we are little bit bellow 4K buffers. In 21.28.mX buffers are increased to 4k. In older version this could be close to 1K.
# If not sure get multiple SSD to confirm.
