My educated case is that it was a bad batch of drives (Bought them
sooner after their introduction). Drives in the enclosure from other
MFR's have held up reliably and heat has been a non-issue.
Dan might want to see if hdparm has a tunable for the TLER setting he's
concerned about. Modern mdadm versions will attempt to rewrite a sector
if there's a read error using parity or mirrors to reconstruct the data.
For this purpose having a short timeout before getting an error would
be preferable to waiting a couple minutes.
