feature request: Show disk Performance estimates when adding disks to servers

It would be nice if we could see what disk performance we should expect as we add disks to a server. As we know, disk performance is based on the disk you are buying itself as well as the server that you attach it to. It would be super helpful to know if we are going to bottleneck our disk upgrades by maintaining current hardware etc. Does this make sense? I know you can look for this info in azure, but trying to keep things all in one place.
Right now, I look up the disk that I want, then have to go find the table for the server to find the speed it can handle, based on CPU amount, etc.

By the way, what is the best VM version for disk throughput (fileserver for instance), it would be nice to have tips for us when selecting servers for various tasks.
