Hopefully this is interesting to some...
Storage is always a concern for me. I also like to have backup systems that are backing up things, repeatedly.
So I opted for building instead of buying a Network Area Storage device (NAS) to hold photos, videos, CPF backups etc.
This isn't my only backup, but I wanted it to be do be my local onsite storage.
I looked at prebuilt offerings, and I didn't like everything they offered. I found a guide that said hey instead of buying a $500 machine, build it for $130. So off that rabbit hole I go. The key to the $130 machine was to buy used enterprise level equipment off ebay to build your NAS.
So I've bought motherboards, CPU's and hard drives that all had a previous life sitting in server racks running for companies like Oracle, and Sass.
I've built a pretty heft machine that has 7 hard drives, with 32gb of ram (the older ram is so cheap, so I decked it out for a few dollars more).
I also bought silent (slow moving) fans to keep the entire system cool, but again focusing on quiet). I'm using a RAID card that manages the storage of all the drives. I use a small SSD drive to load things I use frequently to make the system quite fast for loading etc.
So I have a system now that has 20 terabytes of storage....and 2 of the hard drives are parity drives, basically keeping things safe, and should something go wrong, I can lose up to 2 hard drives at anytime. The probability is low that would happen, but if I did I can have a drive here in less than a week thanks to eBay.
I know some of you like pictures, so here is the pics of the machine as I built, and all those hard drives.
