Ok I've got a business I've been supporting from day 1. The are in Marketing. It started as 2 people and has exploded to 5 with a few more to be added. When I say exploded it happened fast. We have them setup currently on a wd raided nas (6tb useable) the space is still fine for now as they are offloading old projects to cold storage when they are officially done. However with more and more people using the nas it has shown itself to be unreliable in some cases where they are attempting to transfer large video files and getting disconnected during transfer, and when everyone is using it it doesn't do a good job of balancing the traffic. They are still a small business and every penny counts. I've thought about building an inexpensive freenas system for them with a mirrored raid of some wd red or enterprise drives. While build it yourself is great for my projects I would rather stick to a warrantied off the shelf product in case of failure. They have offsite backup currently being ran by one of the computers mapped to the network drive. I know there are people here who have gone through this and I'm looking for the answers that come with experience.
Thank you in advance!
