Yeah... that's been my past experience with USB docks, at least any with more than one slot. I've never had great luck with them. "Can recover from power outage without being touched" is a key requirement for my NAS so I'll give that one a pass and stick with my "SATA drives directly attached to a SAS controller" strategy for now. Thanks for the reply.

As for the 24/7 use, yeah so be it. The I in RAID stands for Inexpensive. If they fail after 10 years at 24/7, so be it. I have drive level redundancy and frequent offsite backups of anything critical.

It's absolutely the stupidest solution, but SwitchBot Bot is a home-automation button pusher. They are quite cheap on ebay (especially compared to the price of hard drives) but still a face-meltingly stupid problem to have. https://us.switch-bot.com/products/switchbot-bot

I have quite a mix of 2x and 4x drive enclosures, and generally I don't notice anything particularly odd about them? Some enclosures have degraded smart or power management capabilities though. I really wish I'd noticed at the time & sent those ones back! What a waste! My favorite are some dual slot HighPoint toaster-style ones that have independent USB connections per drive, which rocks, but these are so rare & I almost never take advantage of it (replug on drive into a different mini-pc).
