Nowadays, sata interface is obsolete too. What I don't consider obsolete from the past deals with PS/2 interface.

Please let it be USB-C (Thunderbolt). That would be good for 4 PCIe lanes and power! We don't need yet another connector and cables and whatnot.
That said, there's no reason someone couldn't make a pretty simple USB-C or Thunderbolt to U.2 adapter. USB-C can provide enough power for even a spinning drive and it can use PCI-E alt mode for the data path as well. But using native Thunderbold/USB-C for an internal spinning drive is a bad decision.

OK I am curious. What possible use does PS/2 serve these days that isn't better served by USB other than wake on keyboard? I have to admit it surprises me every time I buy a mobo and it still has a PS/2 connector even if they have gotten down to one.

Seagate should just produce better SSDs instead of trying to push old technologies, that draw too much power and needed to die yesterday.
The next thing they do is to hold up future NVMe interface specifications because they have to include compatibility features for old HDD technologies.

The difference is in communication/control: interrupt-based (PS/2) vs polling (USB). Therefore, You can not get full NKRO with USB.
The latter mode is much simpler for a keyboard to implement as it's just a simple representation of what the keyboard controller has to generate as it scans the key matrix. The 'simple mode' actually takes more complexity in the keyboard controller to parse through the keys and package them into the USB message. But, the bit field method requires the OS (or BIOS) to remember the state of the keyboard and early BIOSes didn't do that. So, all keyboards ended up supporting at least the 'simple' mode for the sake of BIOS compatability. Nowdays that's less of an issue, but is still causes confusion from time to time.
Here's a good video on it:
