> Is a USB-C enclosure actually faster than USB 3.1 was with the old conenctors?

As I understand it, USB-C-to-USB-C (with USB 3.2) is the only connector combination supporting Gen 2×2, 20Gb/s mode (since it leverages the pins included to support flipping the connector; it's also the only combination to support Gen 1×2, but that's the same speed as Gen 2×1, so it's unclear why you'd do that.)

USB A (w/USB 3.1+) can support Gen 2×1 (SuperSpeed+) at 10Gb/s. USB B (w/USB 3.0+), AFAIK, only supports Gen 1 (SuperSpeed) (5Gb/s).

Ah you're right. First I've heard of USB 3.2, but here's news from 2017: https://www.anandtech.com/show/11667/usb32-update

I have a USB-C drive enclosure, but looking at the specs it's only USB 3.1. Newegg doesn't even have 3.2 as an option when searching by external interface in their hard drive enclosures section. The day when you're actually losing anything by not having USB-C devices seems a ways off still.
