We take a lot of pictures and have other digital assets that we want to be able to access on any computer in the house or home office.
Putting some network attached storage on the network solves many problems. Which one to buy? One of my favorite is the Synology DS series. Two hard drives so you have redundancy, and it's fast. Buy it for $300 and then add two hard drives. I'd suggest the Samsung F4 2tb. It's fast, cool, and quiet.
