If I may ask, which disks are you using?

  the highest end NVMe SSDs can sustain those multi-gigabyte/second reads. https://smile.amazon.com/Samsung-950-PRO-Internal-MZ-V5P512BW/dp/B01639694M https://smile.amazon.com/Samsung-950-PRO-Internal-MZ-V5P512B... for instance. not sure even they could pull off those speeds with random reads, though.

    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.

      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!)

      > I think when most people say "hard disk", they usually mean rotating discs that use magnetism to store data. 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.
