I used my symmetrical upload for work. I'd copy virtual machines home to fix and then copy them back. I hosted VMs that I used as a template. I'd host huge ISOs so I didn't have to carry install DVDs with me.
Past that, it's pretty sweet to be able to access every bit of my home network as if I were there.
But then I moved to an area with one internet option, a cable ISP. I now drive a LOT more than I used to.
Ever transfer a file more than a few hundred gigs? This makes that take less time. Even if I’m only pulling down files at 1800 mbps Ive got plenty of headroom for everything else.
Yes. But I'm asking: what is the need for it?
If you want and are willing to spend the money go ahead. But I'm asking for the use-case.
