Pro 6 reading performance

Sorry I forgot to post the SMART details. I have already checked that the drives were not parking the heads too often, the value is set to 300s




I'll try to check windows errors on my NIC. Haven't found an easy way to do it yet!

I'm sure it was not happening before. The difference may be the new drives. I can try and stick in an old one and see if that happens anyway. I have also upgraded my NIC's driver, I'll test again later.

Thanks for your help!

Edit:

Ok, also found the way to read statistics under windows. it's

netstat -es (to reset statistics, disable and enable your NIC).

Here you go. During the transfer I monitored the NAS statistics. There was already a dropped package, and it stayed there. I believe dropped packages are not bad per se. Those are not errors, are just packages which did not apply/belong to that NIC. I also read somewhere that some Linux kernels/drivers (not a massive expert here) had a bug which was resulting in several dropped packages.

Windows is indeed showing lots of discarded packages, but I have no idea what that does mean.
