Given that there's a separate item for sequential disk reads vs SSD reads, I think it's pretty clear that particular item meant hard drives specifically. Agreed that modern SSDs should be able to pull that off.

Yeah. Terabit networking is not here yet, and it's certainly not "commodity network"-grade. We can LACP a bunch of 100G optics together, but we're probably 5-10 years out for 800G ethernet to become widely adopted and for 1600G to even be developed.
