I'd like to find some good quality but slow nvmes, I dont need super high speed for media serving but getting a lot of storage (4x4tb/2x8tb ~) is much more expensive than hard drives. Itd be nice to have a silent home server
But cheap SSDs got down to 2x the price of hard drives last year. Even after prices stabilized, they're at 3x. Flash catching up relatively soon seems likely. Flash matching the current price of hard drives seems even more likely.
Making sure I'm looking at new hard drives, I see prices around $15/TB at the cheap end. There are a few name-brand SSDs at $45/TB, many more at $50/TB. They're not high end but even the low end is fast these days.
Where can I find info on that roadmap, by the way? I've found a few things but they're very vague about price at best.

list price of $850 or $624 on sale for 8tb
Still way better than the M.2 NVMe drives which can be well over $1000 each.
However, these SATA drives still dominate HDDs in most metrics like random access and sustained transfer with like 560MB/sec. Not great compared to modern NVMe drives at like 7GB/sec, but for reference HDDs are usually less than half that and the random access metrics can be dire.
