I am currently using a following setup:
WD purple 4TB in an Icy Box IB-3620U3 connected to Rpi4 via USB3
TL-WR841N router connected through Ethernet to Rpi4 and my main PC and with WIFI with other network devices
PC: asuz z87-a motherboard (supposedly supports gigabit connection) with i5 4670k and WD blue HDDs
WD drive conencted to Rpi4 has has its contents shared to the other devices through sambashare. NTFS filesystem.
The issue is that the file transfer speed is around 10 MB/s. Considering that the router supports up to 300 Mb/s (both sides) then max transfer over wifi can be no higher than 18 MB/s - is that correct?
However, I expected the file transfer to be done via ethernet, which should yield higher speeds, no? Is my router the bottleneck here?
