Troubleshooting • Re: notional expected transfer speeds for USB3 disks ?

In my experience ...

Those speeds look normal for good hard drives, some very good hard drives achieve SSD speeds at around 300MB/s, budget hard drives would be lucky to achieve those speeds.

Most hard drives I've used are more than five years old (pulls from other equipment).
OK, thanks pidd. Good enough for me. 180MB/s to 190MB/s is close enough to OK max read/transfer rates for this hardware then.

All else being equal ...
  • with say 5 streams in the house @ 20Mbps each
  • and depending on what minidlna and samba are up to
  • and depending on what Pi 5 internal bandwidth limits are
Then I guess it looks like the traffic is going to fit well within a single disk's bandwidth "path" OK, and as fanoush mentioned the limiting factor may be network.
More likely felt by any upstream WiFi devices sharing a 2.4Ghz WiFi connection to the gigabit router rather than being ethernet connected.
I guess time to look at identifying and separating a few onto 5Ghz (history; if it worked then didn't touch it).

Of course I could well be completely wrong, in which case hopefully someone will not hold back in pointing it out.
