Well, 300MB/s is to be expected due to the architecture of Mantiz and TB3. That is a "normal" result for this configuration.

I suppose you, @gnu and @ikir are connected with a TB3 4x, not 2x.

 

Instead it seems @Rusty is connected with a TB3 @2x, so he has 225MB/s max speed. Either this is to be expected on 2x. BUT the 140MB/s on Sata, no, that does not make sense...

@Rusty:

1) are you connected on TB3 2x?

2) are you copying the same files on USB and Sata ports? To understand it better you should do a CrystalDisk Benchmark on both. Of course, all the test without using the eGpu...

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Which port on the Macbook Pro 2017 should I connect? The left one closer to the screen?

2017 15" MacBook Pro (RP555) [7th,4C,H] + GTX 1080 Ti @ 32Gbps-TB3 (Mantiz Venus) + macOS 10.12.6 & Win10 [build link]

If you are using the 13" MBP I think it is the left side ports that are full speed and the right side ports are slowed, on the MBP 15" it shouldn't matter and on my 2017 model I have had no issues using all the ports.  I think some people who had issues earlier reported a higher rate of success using the port closest to the headphone jack if I remember correctly.

2017 3.1ghz 15" MBP, 16gb of Ram, and Radeon 560 - Mantiz Venus EGPU with Silverstone SX800-LTI 800W power supply and Noctua fan - EVGA SC 1080TI - LG 34UC87M-B

Moved posts into own dedicated thread looking at Mantiz Venus attached storage performance.
