Hi there!


We installed 2 new Editing Suites in our Company. Two Imacs, one from 2015 and a brand new one from 2017.


The one from 2015 has a SanLink2 TB2 10g Box installed.

The other one a SanLink3 via TB3.


Both Imacs are running 10.12 Sierra.


We tested all our Connections and all available Drivers leading to the Conclusion that we only achieve maximum bandwith via IMacs running El Capitan. 



Is this a driver Problem in Sierra?


Thanks in advance.

Same problem here. Running various generations of iMacs (including most recent 5k) and both SANLink 2 and 3s.

Hi There,


we have same Problem here. Updated on machine to sierra (MacPro) and now we have half read speed on the sanlink2, newest driver is installed. Write speed is about 400 mb/sec, read speed is about 180 mb/sec. All connections are via AFP. 

SMB is very very slow.


Is it a Driver-Problem or a OS X-Problem?


Best regards

Hi Christopher,

Are we to assume that you mounted the network shares using SMB?

Did you try disabling the SMB Signing?
