NSA-220 Plus

JohanFrank

Hallo. I have a question.
i have a NSA-220 Plus with a gigabit ethernet.
my home router has gigabit. And my macbook with a ac wifi card is connected with the router with nearly a gigabit.

but my transfer speeds are 5 MB/s

my ethernet cable is half a meter, and is not cat6 but cat 5e. Is this the problem?

Probably not, unless the cable is really bad. If the cable is a cat5 4 wire cable, you should have an 100Mbit connection, which gives about 10MB/sec. An 8 wire cat5 should give 1 Gbit, which, on an NSA220, should give 20~25 MB/sec, limited by the NAS' cpu.

But if the cable is 'just a cable which happens to have 2 rj45 plugs', for instance an old Annex B phone cable, than anything can happen (for worse).

How are you measuring that speed?

JohanFrank

I used lan speed test and the activity monitor on the mac os.
on the cable cat5e is written. I will check it, but I am sure it has more than 4 wires, I think I will just order a cat 6 cable. If this does not work, i really dont know what the problem is.

Thank you for your help!

Are you copying one big file, or a bunch of small ones? Max throughput can only be accomplished by copying big files.

I tried with one video file 1gb and with a tv show 8 files. Every file was 300MB. Same result, same speed

Either the nsa-220 plus is not nearly gigabit, or I am doing something wrong. I don’t think it is the cat 5e cable. Tried with a cat 5 cable and getting the same result

The NSA220 is fully gigabit connection capable, but it can only handle a datastream of about 200Mbit, due to it's weak processor.

Can't say if it has a gigabit connection now. An 5MB upload is about 50Mbit, so both a 100 or 1000Mbit connection can handle that. The LED's next to the ethernet port should tell you, but I've forgotten how. To have a gigabit connection it needs a gigabit uplink, and an 8 wire cable.

Do you have the possibility to benchmark it all wired? Wifi is not a reliable medium.

Something else, on newer ZyXEL NASses media detection by twonky can eat a lot of CPU while uploading. I can't remember if the NSA220 also had a media player. If so, try to disable it.

 "The LED's next to the ethernet port should tell you, but I've forgotten how. "
I read somewhere that 2 LEDs should light up when it has gigabit. Only 1 LED lights up here.

I have gigabit uplink and a 8 wire cable. It is written "gigabit verified" on the cable.

I need to buy a usb 3 to ethernet for my mac to test everything wired.

I disabled everything and still same result. When copying the CPU is never crossing 88 percent. Usually at 60%

But it is ok. Nevermind. Thank you for your help.
