Thanks for the feedback!

So after trying a few things, I got speeds of 30MB/s using SMB which is much more usable then 10 ; ) and closer to the expect USB bottleneck. From what I read other qnap users get 40-65 MB/s and some 80-100MB/s which would be nice but I think it’s just a matter of having a better NIC ethernet card – would have returned my iMac under warranty is only I would have know this 2 months ago ; (

Ya the processor is a Intel Atom 1.8GHz Single-core Processor 1GB ram. Would you recommend another NAS that works better than the QNAP medium-high grade models?

Anybody know whether the new iMac 27″ i7 May 2011 models really support T-Base 1000 ??

Thanks!

thanks

[Steve Modica] “I think the Qsnap is probably the limiting factor. If I recall correctly, those are pretty low powered. We had one in here for iSCSI testing and it wasn’t very fast. I’d try connecting to another mac as a test.”

Hey Steve! Thanks for the very quick reply!
it’s a QNAP 439 II + Pro (w/ atom processor) but I am transferring using AFP since iSCSI simply isn’t supported for Lion and it seems like the only real option available.

Can it be the AFP that is limiting the speed?

I will do a test between my iMac and MacBook to see what speeds I get. (don’t have acces to 2nd iMac)

Thanks for the help!

Hey @Steve and @Walter!
Thank you guys so much for the insight! Really helps.

I have an iMac 27″ i7 (with the silly T-Base10/100) NIC which suck of course. I got a USB Gigabit ethernet adaptor (with AXIS AX88178) that supports T-Base 1000.

Now, I understand that my iMac DOES NOT support jumbo packet and that the USB interface is 480Mps so I would expect transfer speeds of 30-40MB/s (or at least 20MB/s). But I only get 10-12MB/s transfer speeds which is way to slow and is the same as over WIFI.

MY QUESTION: Is this 10-12MB/s normal?? if not, what should I expect? or how can I get better speed to my NAS?

Any insights or advice would be greatly appreciated
(I don’t really want to sell my iMac (and loose 600$ in the process) just to get one with a proper Ethernet card

Main use: Regularly backup my photography archive to QNAP NAS
Although I enabled T-Base 1000 on Gigabit adaptor and in NAS with 1500 packets.30-40MB/s would do for me as long as 1-2 TB as be transferred over night.

Thanks in advance!
