Dumb question. Why should someone ever buy a HDD nowadays?
16TB 7200 RPM the same price as a 2TB NVME.
Do you want 2TB super fast or 16TB that still can transfer at decent speeds?
The answer is yes.
Because I can't afford 120TB in SSDs...
Still cheaper, i use them for large volumes of data that isn't read or written that often
This will blow your mind, but datacenters still buy tapes. It's just stupid cheap. In the future, chemical storage by DNA or something similar might play the same role for cold storage.
I don't get why we research DNA as storage.
It is sensible as fuck, deteriorates quickly, is slow to write and read...
Only advantage it's bio-compatibility
The information density is insane, both volumetric and by mass.
I sort of agree, though. With current methods it seems like it would probably be just as easy to record information in a synthetic polymer.
They’re great for a NAS, where the priority is high capacity and low cost, over high performance and high cost of SSDs for comparable capacity.
Enterprise 5400 RPM drives for NAS are cheap/quiet/reliable
Because of economy
HDD is still the superior way to store data compared to ssd's. Ssd's are great for accessing your data fast but for people who have a lot of data they don't access regularly the reliability and price of an HDD is unbeatable.

As the other guy said, because they are way cheaper. I use them for media storage.
For 20tb of hard drive storage, you could expect to spend ~$400 (probably less these days), but the same price will get you a 5th that on ssds (maybe more these days)
If you are streaming video, hard drive read speeds are good enough.
