3.5 hours to transfer an image over my network which has a Gigabit router to my WD MyBook Live Hard Drive and 17 minutes to a USB 3 Hard Drive. Do they make Network Hard Drives with a USB 3 so I can just walk over large amounts of data with my WD Passport Hard Drive?

USB3 has a significantly higher (approx 5 times) maximum throughput than gigabit LAN, so it isn't surprising that copying over USB3 is faster than LAN, though that is a far more significant difference than I would have expected. Almost looks like one or both devices are only operating at 100Mbps.

Look at the average data throughput of a hard drive & you'll see the bottleneck is usually the hard drive itself
unless its USB1 on an old PC :badpc:

Youve got some weird issues there, maybee one PC is only connecting to the network at 10Mbps

FWIW, I copied a 2.2GB file to my MYBooklive NAS over a 100Mb network and it took 3m 30s at 11MB/s.

Given the 17 minute transfer time for USB3, I'll assume we're talking an image on the order of ~100GB, which would take ~3 hours on a typical 100mbps LAN, but should be not too dissimilar from the USB3 time (~20min) over a full gigabit LAN. Either your drive(s) are not performing well, or your LAN is not running at gigabit speeds.

Or USB2 - even mechanical hdds can max out a USB 2 connection. Otherwise I agree, gigabit ethernet is faster than most mechanical hdds sustained read/write speeds.
You have a gigabit router, but is everything else in the chain gigabit?
