The HyperDrive does not touch the bottom surface, but it is not only supported by the two Thunderbolt 3 USB-C connectors either. The HyperDrive stays flushed with the MacBook Pro so in addition to the two Thunderbolt 3 USB-C input connectors, it is also getting lateral support from the side of the MacBook Pro. We already had a single connector HyperDrive for the 12" MacBook on the market for about a year (https://www.hypershop.com/collections/usb-type-c) and no user had ever complained about any damaged connectors. If you look at our design, any possible stress would be more on the HyperDrive USB-C connectors than on the MacBook Pro itself. The HyperDrive USB-C connectors are anchored, soldered on the PCB board and double reinforced with a ABS plastic and aluminum frame so it can withstand a lot of stress. If you ever break the HyperDrive USB-C connector, it is covered under warranty but to date, nobody has ever complained about a damaged connector on the single connector HyperDrive and this new HyperDrive with 2 connectors is twice as strong.
