You don't have time to think up there. If you think, you're dead.- Maverick (Top Gun)
I've got a server at home that has my iTunes library on it for Home Sharing to my AppleTVs and it's connected to my AirPort Extreme that has a Drobo hanging off USB 2.0 as an AirDisk. I want this connection to be fast. My speed experiments are really confusing. To test I'm rsync'ing giant files over SMB. ChaosServer is a MacBook Air, so there is no built in ethernet. I have two USB 2.0 to Ethernet adapters - one from Apple and one I bought off eBay for $10 from China.
|Ethernet (Apple) - Left USB||4.27MB/s|
|Ethernet - Thunderbolt||2.10MB/s|
|Ethernet (Apple) - Right USB||1.72MB/s|
|Ethernet (China) - Left USB||307.01kB/s|
If you're like me - you're wondering if the adapter is busted? That is so slow. And the one from China is laughable. So I tried plugging directly from the computer to a MacBook Pro which has builtin gigabit ethernet. The results of that?
|Ethernet (Apple) - Left USB||11.20MB/s|
|Ethernet (China) - Left USB||11.19MB/s|
|Ethernet - Thunderbolt||49.95MB/s|
Wait, what!?! I have no explanation. I guess I should re-run the tests on the computer again. Perhaps there is something crazy happening on Drobo? I'm not sure.
