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

As you edited in your post it sounds to me like a software issue. FTP will always be faster because FTP's goal is to be fast. Its a protocol meant for file transfer. My guess is that your connecting via LAN and thus using windows SMB protocol which is more for file sharing. Also windows will encrypt SMB transmissions which will significantly stagger your transfer speeds. I recommend just staying with an FTP transmission. If my theory is correct, you will see a similar issue in win7

Yes, the question before I start praising this HDD, which protocol you use to transfer files from Ubuntu?

WD Green slow HDD.

Among other things, constantly trying parking, from which the performance degrades even further. The site has a manufacturer firmware changes this behavior - of a parking lot at idle.

You can format a file system with a block size of 8K or 16K (better) - the speed will increase significantly. Yes, you'll pay for it some lost space.

Check the disk for errors and performance issues, perhaps you will be able to replace it under warranty. Green Series is very unreliable. And performance issues, as an option, the problem with the HDD.
