I was hoping to see any mention of large file downloads and uploads. Nevermind the article’s ponderous “I can’t imagine any use case for more than 5GB/s”, that’s a use case today where higher speeds above 5GB/s would be helpful. For example, a lot of AAA games are above 100GB, with the largest game in my steam library being over half a terabyte (DCS World). Ideally I wouldn’t have to store these games locally, but I do if I want to have access to them in any reasonable amount of time.
It also takes ages to back up my computer. 18 terabytes of data in my case, and that’s after pruning another 30 terabytes of data as “unnecessary” to back up.
