I'm still having a hard time understanding all the new connector types for external gear. Anyway, I need an external SSD for audio recording to connect to a new 2017 iMac at our studio. And I'd like it to be as fast as the internal SATA3 SSD I have in my Windows PC, if possible. So what's the difference technically between an external SSD labelled "TB3" (like the LaCie d2 TB3) and one labelled "USB-C" (like the Samsung T3)? I only know they use the same cable. Does the Samsung benefit somehow from being connected to a TB3 port, or does it behave just the same as when connected to a USB-C port on a PC? And what's the real-life speed difference between a TB3 SSD and a USB-C SSD connected to the iMac's TB3 port?
