I'm running into an issue where when performing certain tasks, the transfer speed on my external HDD suddenly drops from ~80MB/s to ~5MB/s, which is preceded by a spike to 100% active time. What could be the cause of this?
#Active disk 100%, transfer rate ~0

Yes, in this case an unpacking program is running and transferring files to it
The two states (80% active time, normal speed and 100% active time, no speed) are while performing the exact same task

Thats normal then

nothing changes except this sudden drop. I remember that I had a similar issue with DrivePool a while back where transfer speed was capped at 5 MB/s

That is the problem with hdd....the nominal transfer speed refers to sequential transfer mode, the random seek transfer mode is really slow.

Oh I see what you mean, so it would likely be a software issue wherein I should tell my software to transfer sequentially
if I want to leverage the nominal transfer speed

Yes and no, transfer speed will be fast if the file is transferred sequentially, but unpacking a program is always random transfer task.
