If you would like to use a USB flash drive to build your eDrive or Protogo device, we first recommend that you use a USB 3 device for best results, even if your Mac is equipped with USB 2. As for the size needed, we recommend a 32 GB device if building an eDrive, or a 16 GB device if using Protogo - using the Basic Profile, which functionally equivalent to the eDrive.
