(While I know this listing is for the Air, I am noting on Pros as well given the size of the 130 fits the older Pros.Apple Mac Mini A1347 (Late 2014) 3.0ghz Intel Core i7 / 16GB RAM / 500GB SSD. And I have been told that there is some variation within single generation MacBook Pros/Airs. Oddly enough, my brother has a 13-inch from the same generation and it is USB 2. In the case of a 2011 15-MacBook Pro I have, it is routed via 1 lane PCIe with a link speed of 2.5 GT/s.

(For those just wondering how well it will work, in summary, a 1-lane PCI Express and USB 3 can theoretically max out the speed of this JetDrive although you rarely will get sustained peak advertised speeds with ANY product.USB 2 cannot as it's max speed is around 1/2 that of this JetDrive's peak read speed.) If the built-in SD Card Reader shows 'Link Speed 2.5 GT/s' at the bottom, this is a 1-lane PCIe rather than USB. Click 'Card Reader' under the 'Hardware' menu tab. If 'Internal Memory Card Reader' is NOT listed here, then I verify that the SD card reader is running through PCIe. This tab will also specify whether the computer is using USB 2.0 or USB 3.0. If 'Internal Memory Card Reader' is listed at all in this USB tab, then the SD card reader runs through USB. The quickest way I've found to verify this is to go to 'About This Mac' -> 'System Report' and then look under the 'Hardware' menu tab click 'USB'. Some laptops will route the SD card reader through USB, which obviously means we are limited to a max of either 480 Mbps (USB2) or 5,000 Mbps (USB 3), but other laptops will route the card reader through PCIe (and to my understanding most Apple desktops do this as well.)
