Dropped harddrive

Probably beyond what the value of your data is, but there are companies (IBM for example) than can dissemble drives and rebuild if the platters are not damaged and in some cases recover data. A quite expensive option.
 
I just bought an NVR drive (WD Purple 8TB) recently for my dad's apartment, it is expensive, like $200 or so if I remember right, and there's also a shortage of it on the market. To answer what it is and why can't you use an SSD on it. It is a drive with applications that are constantly writing and rarely read back, they cache the write in a certain way to continuously write them, support special commands that are only for NVR, low power (often variable rpm), and are designed for durability over random read write performance.

If you put an SSD in an NVR you may not even be able to run it due to the lack of special commands, and even if you can it may not last long (maybe 6 months?), and cost like $500 instead of $200.

If the security footage is not confidential (hallway, parking lot, etc) then just toss it, or bring it to a secure erase place to scrap (Iron Mountain?) Is it for work since it is a rack mount system?
 
Don’t many newer setups use a combination? Especially when response time to access more recent video is important?
Not on NVR’s. Even on a cellular connection I can access my NVR remotely and have video pulled up and playing in less than 15 seconds.
 
To me this is the most puzzling part???
It was in a Unifi UNVR. A hot pluggable drive, easy to install and remove. I think they need to have a better locking mechanism. The UNVR was off and unplugged and I was relocating it to a new rack. At some point it was probably tilted a bit and the drive slid out. I could have briefly touched the latch I guess. Not sure.

It's at a church camp mainly recording activity over the winter when it's closed. Outside camera, cars coming or going.
 
Anyway got a new hard drive, put it in a drive carrier and mailed it to someone to slid in one of the drive bays. It was picked up and is now recording.

Next step is to get a second harddrive for RAID 1.
 
I don't need that quick of a response time. We might not notice something was broken into for days or weeks. Then we would want to look back at cars coming and going.
I know, I don’t really need it either I was just surprised that it can do it. I’ve got a WD purple in mine recording at 4K 15fps.

I've heard of some setups where instant response time is very important, like casinos and bank surveillance. But I'm thinking they would use enterprise class drives and would proactively replace drives well before they will show any wear.
