My current read and write speeds are around 90MB/sec and the problem is that when the two of us edit we get the dreaded spinning wheel. I assume that this is a lag in the data stream, but for what reason I don’t know. It is possible that my local network isn’t working to it’s potential.
We are currently using about 5TB every 6 months so it needs to be upgradable too.
What sort of solutions would you suggest Alex and what is the ball park prices we are looking at?
