I think when most people say "hard disk", they usually mean rotating discs that use magnetism to store data. That is what I took tmyklebu's question to mean, since I too have never heard of a HDD reaching anywhere near 2 GB/s.

while i would personally avoid referring to an SSD as a "hard disk", i was attempting to interpret the original claim in the most charitable possible fashion, since it was utterly absurd if interpreted strictly.
Either way, I learned something. I can picture an array of 20 disks sustaining 2GB/s, but you aren't going to fit 20 disks into a laptop. I didn't realise a high-end SSD could get there, or even how much better regular SSDs are for throughput. (That cost per TB, though!)
not sure even they could pull off those speeds with random reads, though.
