But, unfortunately, there was no drive speed increase. We were hopeful a low-cost solution to this issue would be our NewerTech HDMI Headless 4K Display Emulator. Note: Thunderbolt-equipped drives get the most significant increase, but USB-C drives have seen up to a 25.8% speed increase as well. When using an OWC Envoy Pro EX (Thunderbolt 3) drive connected to an M1 Mac, a USB-C display connected to the OWC Thunderbolt 3 Pro Dock, and the Dock connected to the M1 Mac, there was a 56% write speed increase! The good news here is our Thunderbolt 3 Pro Dock and the Mercury Elite Pro Dock (a unique combination of storage and connectivity) both provide a speed boost.

Connect a TB3 device to the second Thunderbolt port on the M1 Mac AND connect a TB3 OR USB-C display to a Thunderbolt port on the TB3 device.

In this scenario, no external display needs to be connected to the M1 Mac.

Connect a TB3 Dock such as our 14-Port Dock, which offers native multiple display type support (HDMI, DisplayPort, or VGA without needing an active adapter) to the second Thunderbolt port on the M1 Mac.

Connect a TB3 Display to the second Thunderbolt port on the M1 Mac.The storage device (either bus-powered or AC “self-powered”) MUST be connected directly to one of the M1 Mac’s Thunderbolt ports.

In order to get the fastest write speed of an external drive when used in conjunction with an M1 Mac, the following conditions are required: And they uncovered some interesting results. So, in between designing cool new products that we are launching throughout the rest of 2021, our engineering and product development teams took the time to examine a few of their hypotheses thoroughly. We wanted to do some additional testing to see what other device configurations might offer a similar speed boost. In our recent post, Get Up to 67% Faster External Drive Performance With Your M1 Mac, we promised to keep looking into the Thunderbolt drive speed issues.
