I plan to switch to an M1 chip Mac in the coming months. As you know, Apple charges an exorbitant price for storage capacity. Because of that, I am planning to use the Mac with an external NVMe SSD.
Thunderbolt 3 supported NVMe SSD boxes are very expensive so I looked for cheaper boxes. I found a 20 Gbps (USB 3.2 gen 2 × 2) SSD box from several brands, I am thinking of buying this box. But when I look at the technical specifications of the MacBook from Apple's site (image below), it says that USB 3.1 supports up to 10 Gbps. USB 4 supports up to 40 Gbps. Will my SSD box run at 10 Gbps or will it run at 20 Gbps?
So I want to ask this: Does USB 4 have all the previous USB technologies? Will USB 4 itself match the speeds of previous USB versions? If so, I should be able to use this SSD box at 20 Gbps.
