Small Computer System Interface (SCSI, /ˈskʌzi/ SKUZ-ee) is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols, electrical and optical interfaces. SCSI is most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and CD drives, although not all controllers can handle all devices. The SCSI standard defines command sets for specific peripheral device types; the presence of "unknown" as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements.
SCSI is derived from "SASI", the "Shugart Associates System Interface", developed circa 1978 and publicly disclosed in 1981. A SASI controller provided a bridge between a hard disk drive's low-level interface and a host computer, which needed to read blocks of data. SASI controller boards were typically the size of a hard disk drive and were usually physically mounted to the drive's chassis. SASI, which was used in mini- and early microcomputers, defined the interface as using a 50-pin flat ribbon connector which was adopted as the first-generation SCSI (SCSI-1) connector. SASI is a fully compliant subset of SCSI-1 so that many, if not all, of the then-existing SASI controllers were SCSI-1 compatible.

SATA is the dominant interface for hard drives these days, but could SAS be a powerful alternative for your setup, or is it just too impractical?

A "general" look at SCSI (Small Computer System Interface) hard drives and devices. A good video if you're totally new to SCSI and what it is and how it fits into your retro PC
A few SCSI hardware basics on the SCSI system and internal SCSI hard drives.
SCSI drives are known for high performance, running at 10000 or even 15000 RPM as well as low CPU load. However such drives are noisy, hot, draw a lot of power and might not be very reliable. SCSI2SD is a SD Card based SCSI drive, simulating up to 4 SCSI devices and fully configurable through a USB interface. In this video I will check it out for usage in a DOS Retro PC. We will take a look at the unit and will demonstrate how to configure and use it. Enjoy this video! Update: My SCSI2SD has been repaired and returned to me!

Here we go over at a really high level the concepts of SCSI and how to setup a real spinny disk on a big box Amiga. In this case, I'm adding a SCSI drive to an external enclosure as a back up drive for my Amiga A2000.
I'm not a product of your environment
I don't hold these truths to be self-evident
I don't necessarily hate the establishment
but I don't think you really know what I meant what I said
