Hello,

Thank you for sharing so many good pieces of advice and so much information on this forum . However, I have searched a lot of topics and I cannot find a simple answer to my question.

I own a DNS-320 with 2x2TB RAID1 WD HDD and I am replacing it with a newly acquired DNS-327L with 2x4TB RAID1 WD HDD. Both NAS will be on my home network connected by wire to my Freebox Revolution Router.

I would like to transfer my files from my older DNS-320 to the new one. What would be the quickest solution?

Cheers

Link>Welcome!

• What Hardware version is your DNS? Look at the sticker behind or under the device.
• Link>What Firmware version is currently loaded? Found on the DNSs web page under status.
• What region are you located?

I recommend installing a external Gb LAN network switch and connect both DNS and a PC to the switch. Connect one cable from the main host router to the switch as well for internet and router IP address access.

Made in 8 port as well if you want more ports.

Does the DNS have a explorer UI or do you use the PC's explorer to copy files. Either way, I presume you'll need to do the copy and let it go over night. Might start with a small batch of files to make sure they copy first, then go for the next batch or entire lot.

Hi FurryNutz,

Thank you for your reply. I am located in France.

DNS-320 is on 2.05 Firmware as for DNS-327L it seems to be on 1.05 just out of the box. I was planning on upgrading DNS-327L to the lastest one v1.07 as soon as it is set up.

THe Freebox Revolution router has already 4 ethernet 10/100/1000 Base-T ports. Would a DGS-105 between the 2 NAS be faster?

For the file transfer, I was going to do it from the DNS Explorer UI or in FTP but I was wondering if there were some other quicker trick, like:
- mounting one of the DNS-320 2TB drive has a second volume one the DNS-327L. Copyinf the files to the new 4TB drive and then installing the 2nd 4TB drive and making a RAID1.
- Or maybe mounting one of the old 2TB as an external drive plugged into the DNS-327L in USB?

Getting them connected on a external Gb switch would be best to avoid any router interferences during the copy process.

No, you can't mount the drive from the 320 in the 327. Do not attempt this. 

USB will be a bottle neck on speed. Best way is using the Gb switch. You can try a couple of small tests using the DNS UI or Windows Explorer to see. See which one works best. Then go from there.

Hi FurryNutz,

Thank you for the advice. I received my DGS-105 today and wow it makes a hell of a difference. I first gave it a try with both NAS connected to the router of the Freebox, using the "local backup" app and I got a mere 15MB/s transfer rate. With both NAS connected to the DGS-105 (and some new RJ45 CAT6 cables), I get 850MB/s transfer rate. This is brilliant!!!

Cheers

There ya go. Hope it works well for you. Enjoy.

Hi FurryNutz,

Correction, I forgot one division by 60 - "With both NAS connected to the DGS-105 (and some new RJ45 CAT6 cables), I get 850MB/min transfer rate" which is 14.2MB/s. So it is actually slightly slower with the switch than directly with the Freebox router!?! 

All the lights are green which should means that the connections should be on 1000MB/s. What am I doing wrong?

[FurryNutz]

Try setting up some static IP addresses for each DNS.

See if each DNS has manual LAN port speed settings maybe.

Hi,

Well, boh DNSs are on fixed IP, both are forced to 1000 Full Duplex on their respective Network settings. The link between the switch and the Freebox is also set to 1000T-FD and the lights are flashing "Green". I also tried with the DNSs both connected directly to the Freebox, but I cannot get past the 18-19MB/s transfer rate!

Hi again,

I seem to have found some answers from those two websites:
- http://geeknewscentral.com/2011/03/27/network-switches/
- http://www.tomshardware.co.uk/gigabit-ethernet-bandwidth,review-31611-4.html

The limitation might come from the HDDs read/write speed and in fact 18MB/s over a 1000Mb network seems to be already pretty good, for a standard home network environment.

The theoretical 125MB/s transfer rate of a 1000Mb network can be reached (111MB/s) when transferring from RAM to RAM. SSDs could be the way forward, but I guess 2 SSDs of 4TB (if that even exists) would be a bit too pricey  .

I will give JDowloader a try and see what transfer rate is acheived.

[FurryNutz]

Yes HDDs have some limitations on there speeds.

For what it's worth, I see 70-90Mb (READ) when I use my DNS-345. I presume between the DNS processor, 1Gb and 10Gb cabling I have installed and the HDDs I have in the DNS, maybe why I see these speeds. Even thru a DWA-192 AC1300 wireless USB adapter and DIR=890L on Mac, speeds are nice. There maybe some limitations seen with these model DNSs as well.

Another factor maybe that your doing READ from one DNS and WRITE to the other. WRITE usually is always slower than READ.
Here's my router test results with my DNS and DIR-880L a couple of years ago:
