You're a few spinning metal disks with a mechanical arm that physically moves. I can hear1 you. Surely your evolution must have peaked in the mid-2010s. You have no business needing more than High Speed USB 2.0 bandwidth. How are you even able to reach 200 MB/s (megabytes, not megabits!) when defragmenting. Why is my network file copy not bottlenecked by the HDDs on both ends, but by the Gigabit Ethernet connection?

Like, I know that HDD speeds haven't actually stopped evolving 10 years ago. I am aware that the practical slowness of HDDs comes from seeking and that they do much better at sequential IO. But it still feels strange to me when an HDD manages more than a few tens of MB/s.


  1. though some modern HDDs make it surprisingly difficult!

(the start of the title got rendered as "hd-ds" in the chost URL, because of course. Are they using the same algorithm as those old-style wiki systems, which would have made it a link to the "HD Ds" page?)

(not a serious complaint, I know this is actually a hard problem)
