I would expect it to be a cable issue. I had long after market power cables on a consumer (Corsair) PSU which caused a voltage drop of about 1V which was enough to cause errors.

Dodgy SATA/SAS cables can also cause it.

The SAS controller overheating can also do it. I had them again when I didn't have a fan on my LSI card.

Stable Diffusion has a bunch of tagging libraries used for training models. Something like BLIP might work, but it produces a text description of the image which may or may not be what you want.

Some of them don't pass SMART data, or worse, pass the same data for all drives. Check the Amazon/external reviews.

I just bought a QNAP TL-D800C that looks pretty good and was on a BF sale.

Was this the L1Techs video? I think he's planning on doing a proper comparison/review of USB enclosures which would answer some questions.

I would get a proper server case with a backplane. It'll save so many headaches with cable management, and they distribute power a lot more safely than running many long cables would.

My system has been a lot more stable since I started using a hot swap backplane and server PSU. Before that I would lose a drive every 3-6 months. It's also a lot quieter and the drives run cooler.

They don't get sold so much because the EU holds sellers accountable for faulty products a lot more. Plus GDPR makes it simpler to shred drives than wipe and resell them.
