One of your devices is failing on superblock write. You cannot save it,
at least not with that USB interface. Leave it out of your assemble
command. Use --force.
mdadm --assemble --verbose --force /dev/md127 /dev/sd[ce]1

Report what it prints. If it works, immediately back up what you need
(there won't be a rebuild).
After you recover any critical data, blow away and reconstruct the
entire array using proper SATA ports.
Include in your system's boot scripts the following:
for x in /sys/block/sd[whatever]/device/timeout ; do echo 180 > $x ; done
