I just finished setting up and migrating stuff from XU4 to H2. For anybody thinking about making their own NAS with oDroid H2, in the form shwon here in the thread or in the classical form (with 2 HDDs), while transferring from an USB 3.0 HDD to the SATA HDD I got speeds of 120-130 MB/s (it took about 8 hours to transfer 3.5 TB from the external HDD to the internal one just because I had small size files, besides large multimedia files). I am more than pleased with it. It looks very, very cool with the transparent case and it handles operation gracefully. I got around 100 MB/s on Samba transfers to my desktop. H2 is a beauty and a beast.

This is not the limit, some have already received 14...15 Gbit/s (1.6-1.8 GB/s) ;)

@RomaT: don't spoil the man's fun :D Now 100MB/s will look inadequate :D

@RomaT @mad_ady: I am more than ok with transfers over or around 100 MB/s in my local network (I do not plan to go over 1 Gigabit for now, it would cost too much). I know that this setup is capable of more or that we can achieve more. That test is a theoretical speed obtained with iperf, not bad, but hardly not a real life scenario. I got arount 930-950 MB/s with my XU4 in the past, I did not test H2 as I am more than pleased with its setup now.

I need 1gbit in local network. We can have up to 1gbit fiber in to the house. And soon all children going to download and streaming a lot of things.

So i have now start to upgrade my local network between server and router so it can Handel all workload.

Have you thought about thin and fat clients and booting PXE?

Where can you find a thin client terminal these days?

this must be sought not in the store, but in the head, the rest is done by hands ;)
start, for example, by moving client drives to the server, and the client simply mounts them as network drives.
and the client can be both a PC and laptop and a smartphone and TV and Odroid boards, etc.
i.e. just create your own data cloud in your basement.

Yes, I meant a laptop-like device that acts as the client. Back in the day SUN would sell thin clients without a disk where you would do everything over the network.

But today, I'm not so sure about use cases. A gaming pc needs local cpu and fast local storage. A "chromebook" doesn't need much local storage, but may need loads of ram. The disadvantages of a thin client in a chromebook role are:
1. you need ethernet
2. you can't use it outside of your home.

The big advantage of thin clients was client roaming from terminal to terminal. Unless you have a really big house/loads of terminals, it's not an advantage...
But maybe I'm wrong and there are other valid use cases.

This is a fat client, which has a powerful processor and memory and a graphics card and a small SSD for OS
fast storage is just a high-speed network and a mounted network drive.
I repeat, "thin" or "fat/thick" clients are just a name, and the implementation depends only on savvy.

I don't know... Unless you go with @domith's 40/56Gbps network, 1Gbps over LAN is much slower throughput than 400MB/s local ssd. I agree, it vastly depends on one's needs. Maybe 10Gbps will bridge the gap without burning a big hole in our wallets.

the essence of is if you invest in infrastructure, you will save on each item separately.
which ultimately costs less than with poor infrastructure.
IMHO: I’m saying that doing NAS with the 1GbE network interface today is a bad idea,
5GBE in the short term is normal, 10GbE - good,
more than 10GbE- it's overkill for today, but it's good for the long term and not with Odroid-H2.
P.S.: in odroid H2 limitation PCIe bus - four-lanes v2.0 is the maximum speed of 2GB/s (16Gbps)

To overcome a possible saturation of the 1 Gbit network I would use several small servers like the HC1 or HC2, all connected through Gigabit. I mean you really need like constant transfers from capable devices to actually fill 1 Gigabit. Internet providers offer 300 and 500 Mbit connections for a fair price. If everybody is streaming their own 4K content independently, downloading through Steam and through on several PCs, then 1 Gbit will definitely not be enough. I would actually use managed switches, load balancing and so on, there is much optimization to be done. There are still people with 100 Mbit wired houses and 56 Mbit Internet connections. I think 5 Gigabit would become the norm in about 5 years, when 8K content would probably be as mainstream as 4K content is now.

1. Actually, that’s about NAS, not about Internet content (speed Internet access nothing to do with).
2. motherboard manufacturers have already launched integrated network interfaces 2.5/5Gbps
NAS manufacturers already release with 10GbE
i.e. it’s already going on, and after 5 years everyone will have it, as 1GBe now.
3. Well, about the speed of Internet access https://www.speedtest.net/result/7914234600

To get good stability in local network you need have good backbone capacity. The other is how how setup up the connections.

I have AA house that are tre floors and basement.
So backbone need to be slot more BW then out to the clients. Then if you use one Nas that constant uses you also need to have overflow of bandwidth. If you not you going to notis that you not get that capacity that you Wish you.

Less jump between to Mitch switch and switch. And don't put all floor on same switch. I am going to put one switch on every Flor and fiber between this switch. An fiber between router and fiber switch. I can have then 10 clients att the same time running 1gbit locally streaming or copy between clients Without noticing any loss.

Notis we have 3 children and one on the way ;)

Congratulations! Parenting these days involves doing backbone capacity upgrades it seems :lol:
I took the opposite approach. The kids are on dial-up until further notice. Not bandwidth hogs in my network :D

I was surprised that in the new layout, the average temperature fell by 2-3 degrees Celsius.
in the previous layout, the average temperature was +43...+47С, now +41...+43С
