Back again on my laptop...
Yeah, I think it's time to upgrade cases. I've been worrying about the location of one of the drives - sitting on its side out of direct airflow - so it wasn't much of a surprise to find out that was the one that had failed.
The PSU is proprietary so the only choice if I want less heat and more watts is to change case. Sucks because I bought it at the same time as the drives.
As for batches of drives - they are actually all different batches, made in different countries... China, Singapore, and Thailand. I thought this was great because it means there's less chance of multiple concurrent failures. Given that the average failure rate so far is one dud per month so maybe that's not so great.
