I don't understand. SATA is good enough for your internal hard drives, but for external you need Thunderbolt? USB 3.1 and Thunderbolt are both faster than SATA 6.
Can't we just stick to USB 3.1 that is backwards compatible with every device on the market and faster than SATA.
I didn't know about the USB compatibility. I knew about the display port. I just looked it up and wow Thunderbolt is nice. I was thinking of Thunderbolt 2 I guess. The problem is it's an Intel tech so AMD boards won't have it as readily, and mobile devices not from Intel won't use it. USB is the king. Just how Blueray beat HD-DVD even though HD was better and microsoft wanted it to win. And USB 2 devices are so cheap it keeps the USB brand alive.
You're mistaken, Thunderbolt is just as backwards compatible because Thunderbolt 3 ports all also support USB 3.1. Also Thunderbolt 3 can carry DisplayPort signals and support higher bandwidth devices than USB-C. You're not losing anything with Thunderbolt 3, only gaining.
