I've gone all-in on HGST for personal use because I've seen their results from Backblaze and also have good luck with them so far. I have 14 of their 4TB NAS and 22 of the 6TB NAS.
That's more than my employer's Hadoop cluster...
(Context: http://archive.fortune.com/2006/11/30/magazines/fortune/obri... )
Even so it seems like a lot.
I started with 12 x 4TB in one NAS and I filled it in a little over 2 years. I just recently built a second NAS with 20 x 6TB to last me hopefully for the next several years.
The other remaining drives unaccounted for are in two workstations for local storage.
Uncompressed 4k @ 24fps, at 10bit color comes in at 324MB/s, so just being a wedding videographer could be 1.1T per hour of video. Any given small project could eat up 15-20T per project.
I returned it.

Who needs that much storage for personal use?
1: Not sure what encodig
2: Napkin calculation, corrections welcome
Hint, hint, to clever founders: hard drives in Hollywood.
NAS #1 is 12 x 4TB with 2 drives used for parity.
NAS #2 is 20 x 6TB with 4 drives used for parity.
That takes away roughly 32TB of usable space under zfs. NAS #1 has 40TB usable. NAS #2 has 96TB usable. Total 136TB usable.
The remainder of the drives not accounted in the list above are in workstations for local storage and other random tasks.
I'd record to ProRes or DNxHR if I could, but there's no viable method for doing that on Windows without using an FFMPEG pipeline (which won't do 4:4:4 color sampling with those codecs and simply uses too much CPU at 4:2:2).
That's "home delivery" video, not the stuff you work on which would be far less compressed or even uncompressed, and would include reams of data thrown out entirely at the final production stages.
Think about the difference between "work" (mixing/mastering/production) audio data (uncompressed and at 24 or 32 bits) versus "consumer" audio (mp3/aac at 48/16).
I've bought 10TB of storage space every year for the past 3 years and don't see myself stopping. I need the storage space! If these data-heavy hobbies were instead my daytime job I could easily see myself needing 100TB+ in storage (and then 100TB+ of backups). I fill roughly 8TB/year in storage space (4TB of data + 4TB backup data).
Some people believe in redundant backups. I only have redundant backups of extremely important information - which are mostly text documents so don't take up much space. But if someone was storing 3 copies of all of their media assets you end up using a lot of space. For example, 10TB of video turns into 30TB of video. And 180TB is really only 60TB of data, which isn't that much for data heavy hobbies.
