IMHO, it was a mistake to make USB block storage use the same line of names also used for local hard disks. Sure, the block device drivers for USB mass storage internally hook into the SCSI subsystem to provide block level access, and that's why the drives are called sd[something], but why should I as an end user have to care about that? A USB drive is very much not the same thing for me as a SCSI harddisk. A NVMe drive on the other hand, kinda sorta is, at least from a practical purpose point of view, yet NVMe drives get a completely different naming scheme.
That aside, suggest you use lsblk before dd.
At least sata is well on its way towards dying, so the problem will solve itself in some more years.
My machines all have nvme exclusively now, only some servers are left using sata. And I would say the type of user at risk of fucking up a dd command (which 95% of the time should be a cp command) doesn't deal with servers. Those are also not machines you plug thumb drives into commonly.
In 5-10 years we will think of sda as the usb drive, and it'll be a fun-fact that sda used to be the boot drive.
S-ATA still is the only way to have more than two drives in the system.
My motherboard has 3 nvme bays.
If I saw the need, there are cheap pcie to nvme cards, since (non-sata) nvme is just directing pcie lanes to the ssd anyway.
But like I said below, I don't even have the need to get a single ssd at the currently maximum price-effective size of 4TB, no less two or three.
In my observation putting mass storage into your pc is dying in favor of either not needing that much storage, or putting it in a nas or other internet-accessible device.
Even my non-IT friends do things like put their hdd in a usb enclosure and attach it to their (internet accessible) router.
