Extremely Slow USB 3.0 Speeds

Hi there,

I am transferring large amounts of data (250GB-1.5TB chunks) from 5x 5400rpm 2TB drives to 5x 7200rpm 2TB drives simultaneously (via copy/paste in explorer) and the transfer speeds are incredibly slow. Initially the USB 3.0 speeds show up as quite fast (150mb/ps+) but then they slow down to around 3mb/ps.

The drives have not been manually defragmented but the vast majority of the files on each are video files of the same format (3.9GB each or less).

I am wondering if the amount of drives/data being used/sent is what is causing such slow speeds or if there might be another culprit? I would be incredibly appreciative to learn of any solutions to increase speed significantly. Many thanks...

Been doing a similar thing of transfering video to an external USB3 drive with the same speed results you are getting.
