Yeah, but need to figure out how to see transfer speed using ssh. Sorry noob here :)

If you use scp (cp over ssh) you should see the transfer speed.

I have managed to copy with rsync and getting 180 MB/s. I guess my initial assumption was wrong, HDD is obviously not bottleneck here, it can get close to ISP speed. Thank you for pointing this out, Ill do more testing these days. Im kinda shocked because I never knew HDD can be that fast. Gonna reread all the comments as well

The cool thing about rsync is that it goes ”BRRRRRRRRR!” like a warthog… the plane… and it can saturate the receiving drive or array depending on your network and client. And getting 180 with rsync… on a SATA drive, can’t really hope for more.
And you can run a quick n dirty test is using dd
$> dd if=/dev/zero of=1g-testfile bs=1g count=1

The limitation of HDDs was never sequential Read/Write when it comes to day to day use on a PC.
The huge difference to an SSD is when data is written or read not sequentially, often referred to random I/O.
