The "S" is for SCSI - the Small Computer System Interface - that was used to connect hard drives beginning in 1986.
The control protocol defined there has been reused with the the IDE, SATA, and USB Storage physical layers.
The Linux kernel makes all these devices look as if they are SCSI, at some level. If you look at the kernel configure you will see this.
The system I am on now has /dev/nvme0, a solid state device, so eventually /dev/sdx will become extinct for all but USB Storage.
I agree the book text should be modernized in this area, at least to mention the possibility of solid state being different.
