Earlier today I got email notification about read errors in the array and now my shares are unavailable.  It's strange that it's a cluster of drives on the same controller which makes me think it could be a connection.  Can someone please advise if I need to be worried.

Syslog is being spammed with USB errors which makes it much more difficult to look at, but yes the issue is on 4 drives using the same controller, they likely also share the same miniSAS cable, could also be a power issue if they also share that, it's these disks:
