Sorry - not that deeply into modern SSD (never written a driver for one), but based on my understanding your TRIM theory makes sense to me. I'd try turning it off. It does seem to be an ongoing source of snafus.

I did use WD Blue SSDs but I suspect they vary quite a bit. I've had rather too many early failures. I wouldn't use them in production but okay for Windoze. We all know deep down there's a reason the enterprise SSDs cost what they do :-)

I'll keep thinking
