Speed is actually decent for my use-cases. Just a full RAID check or
replacing a disk can take a bit longer. It was a different story
with my first try with a Pi 3 and its USB2 ports :D.

The event counts are as follows (as can be seen in the full mdadm
outputs at the bottom of my previous email):

dm-9: 2554492
dm-10: 2554488
dm-11: 2554490
dm-12: 2554495
dm-13: 2554495

Are these the counters you were asking for?
