I'm using Ultracopier
to copy some data from Synology NAS to a LaCie Porsche Design 8TB HDD connected to USB 3 port on windows 7 PC
NAS & PC are both wired into BT Home hub 5
UltraCopier interface suggests the transfer speed is between 8.5 upto to about 10 MB/s
Whereas this page review
suggests the Lacie HDD is capable of 192.5MB/s read and 182MB/s write
There is a USB 2.0 port on the Synology NAS but this is only accessibly via a web interface in the past this has proved unstable for file transfer
My question is why is UltraCopier saying 10 MB/s but LaCie HDD in theory can write @ 180 MB/s?
