Hard drive recommendation for storing your assets?

You might want to look into a NAS. Something like this:
https://www.amazon.com/dp/B087Z6SNC1/ref...UTF8&psc=1

Really helpful for accessing your files over the net and backups. In windows you can map the network drive for easy access. You can also get special NAS HDD to fill it with, that spin at a higher speed, and are more geared towards running 24/7.
FYI, if you go this route, you have to buy twice the amount of data that you need, because of how it backs up. If you want to back up 2TB of data, you need Two 2TB drives.
