~4 years ago a Win10 Inspiron PC got slow after I physically moved it across town. I eventually realized the HDD was the culprit; it was getting only about 4MB/s write speed and could have easily been damaged in the move.
The PC has been a reliable media server ever since, just very slow.
Fast forward to today when I finally got a replacement HDD. But when I plugged it in, it ALSO got only 4MB/s write speed. Swapped SATA cables. No change. The new drive is also getting 4MB/s write speed, same as the old drive.
On a whim I plugged the other power connecter from the same power cable into the HDD (from P3 to P5 in the picture below). That caused write speed to jump to ~8MB/s. WTF?
8MB/s is still horrendously slow, but how could a different power connector on the same power cable cause a disk speed increase? Does that indicate a PSU problem? The PC has been fine in the years since the disk slowness first occurred; no unexpected shutdowns that I'd normally associate with a bad PSU. I'm struggling to make sense of this. Other than swapping PSUs (I don't have another one), ideas for how to figure out what's actually broken here?
