I noticed last night the second Lenovo PX4 I bought was still in its box and the 30 day warranty maybe passed, so I grabbed some handy drives and got it going. Works fine, but can't have 10TB just sitting there empty, so picked some likely folders to back up and dragged and dropped, then as the count climbed and climbed instantly regretted. Worse the transfer rate was hitting a hard limit about 10MB/s, time to complete was more than one day.
What have I done? Turns out learned something useful.
Left it alone to eat some breakfast, couple hours later still crawling, so I started looking around. My switch did not have the same colors on all ports, wonder what that means. It means 4 of the 8 ports, including the one to my new NAS, were using low quality CAT5 or worse cables and NOT running at 1000BT, in some cases maybe not even 100BT. Paused xfer, swapped in a new cable, resumed and now much better more or less depending on file sizes speeds of 50 to 100MB/s.
