I recently had an issue where my network switch was limiting my upload speed to 100mbps. It would be great to have a tool, sort of like speed test for testing internet speeds, but to test things like network speed, read/write speed for all the drives, etc. This would be especially helpful in the setup phase when you're choosing your configuration if it could give you that extra information about how fast your networking and drives actually are. And it would also be nice in situations like mine where I could see that the network was only downloading 100gbps, but I didn't know if that was my nas, the computer it was uploading from, etc.
