@mario transfer rates are mostly just what type of controller the slap onto the board, and SATA SSDs are very much in demand. I mean, even M.2 SATAs exist and quite popular in somewhat niche applications. I have two of those - one is USB Pi4 case "addon" and other is an addon to a mITX case - it fills the slim-ODD slot and gives additional usb ports, card reader and M.2. SATA SSD, latter is just connected to motherboard using normal SATA cable.
