I’ve had a fair amount of experience with Unity and Terrablock and just this week purchased the new Nexis E4 with 120TB. It was nice to see the cost for 120TB from Avid finally be at a price that I think is fair (approx. $60K without without switch). However, I did have an opportunity to test San fusions product and was really blown away. If you have someone on staff that is tech savvy with Unix you could build a system for far less than any other system. I had a 24TB retired server sitting on a shelf so we put FreeBSD on it and within an hour I had a multi seat Avid bin locking system using San Fusion. They don’t put any software on the server itself, it’s all done through the client software. I was very impressed. The product worked well and when I had a recommendation for the client software the support staff took interest and I believe it’s now part of the software. The only reason I chose to go with the Nexis over San Fusion is that our company requires 24/7 uptime. This means for support I only want to call one company and not have anyone suggest it’s not their problem (switch, server, OS, etc).
Anyway, my 2 cents.
