For a couple of years I had a Linux NAS box under my desk with like 8 Samsung 850 pros in a big array connected to my desktop over 40GbE. Then NVMe became a common thing and the complexity wasn't worthwhile.
You should see the book requests posted to communities like r/printsf now. We have genre readers that have evolved into "I only read material containing this exact set of tropes" it's straight up weird.
Meanwhile I'm over here jamming Micron 7450 pros into my work laptop for better sync write performance.
I have very little trust in consumer flash these days after seeing the firmware shortcuts and stealth hardware replacements manufacturers resort to to cut costs.
Have a solid vendor for these that isn't insanely priced (for home use)? The last couple I tried to buy they sent 7300's and tried to buy me off with a small refund (eBay).
