So I finally got all my parts delivered to setup a home file/backup server this week.
It's currently running Ubuntu Server and I'm using Samba to share files on my network.
The server currently has a 2TB WD Green drive in it connected to a Asus M5A78L-M
This is then connected via CAT6a to my new Gigabit switch (TP-Link TL-SG1005D). My home desktop is then also connected to this switch and again also through CAT6a cable.
Currently when transfering files I will get a perfect 100MB/s read from the server to my Windows machine. When copying from my Windows machine to the server I get around 30/38MB/s.
I know this drive is capable is faster speeds so would anybody have an idea of where the bottleneck is?
Any help would be greatly appreciated :)
EDIT: I have found ftp's write speed is much closer to what my Samba read speed is so I'm going to give it a guess that is a software problem rather than hardware
dd if=/dev/urandom of=/mnt/disk/testfile bs=1M count=100
That should give you a good indication of disk write speed. It will see how long it takes to create a 100MB file.
