My Lian Li NAS Troubles

Lian Li EX-40N-i

So having just moved house recently and acquiring a new house mate, I have been blessed with the presence of a 5.4tB NAS connected to my network.

I thought that this was going to be a wonderful situation, seeing as it had nothing on there to begin with and, being the file horder that I am, was quickly filled up my 4x1tB Hard drives in 2x2tB RAID0 Arrays.
Brilliant I though, what ill do, is move everything off of my 1tB drives on to the NAS, rejig the RAID and move all the data back over! Excellent idea! It would have kept everything in the one spot (I hate having lots of individual drives, I mean, who doesnt?).

The NAS in question, is a Lian Li EX-40N, contained with it, 4x2tB Western Digital Drives (im not sure if they are ‘Greens’ or not as i didnt put them in there) in a RAID5 setup for a bit of redundancy. Excellent, so far so good.
Right, lets get moving some data over to it. Having a poke around in the WebUI for the NAS I found the ‘Settings’ page for all the service that is has running on it. First thing I looked for was FTP and low and behold, there it is disabled. I tick the box, enabled the FTP server. Ok, setup the username and password and lets queue everything up in Filezilla and away we go!

A bit of time passes and I go back to check on the queue to see how far along it is and to my horror, its transferring 2 threads at a total of 4mB/s??!! What the? What gives? This isnt good, ive got the best part of 4tB to transfer at this rate, its going to takes many days to complete!

Having a poke around on my computer to see if i could figure out what was causing it. Checked SMB shares, nope, nothing open. Check network usage, nope 5-10% tops. Whats going on? I cant figure it out!

So, I ask the housemate for the box the thing came in to see if i could see some specs on the internals of the NAS and low and behold, what do i find? This little trinket of information:

CORTINA ILCS3516C CPU 300Mhz
DDR RAM 128MB

Well ill be!

This now proves that the NAS has next to zero throughput on it, but it raises a very good question, WHY LIAN LI have you decided to put a Gigabit Ethernet Controller onto the NAS and then power it by a 300mhz CPU that wont even do 100mbit?

WHY?
