Nothing particularly wrong with NTFS, it's Windows filesystem architecture that is slow.
I don't recall it particularly ranty, though.
I chose the word because I remembered it being a bit rant-adjacent ("we're used to doing it this way, ... but windows does it that way"). But it's been a while since I watched it (not particularly attentively either, to be honest). That's just what stuck.
The readwrite driver is new, but it always had an older readonly driver too, which would be fine for benchmarking.
Back in 2011 Tuxera's proprietary Linux NTFS driver was maybe faster than ext as well: https://www.phoronix.com/news/OTU5Ng
