One of the great things about the modern interconnected world is that it has become a lot easier to find who has already been banging their heads on similar problems, and what the possible solutions are.

HcX Floppy Emulator

This device is an emulator of Floppy Disk Drive. It still requires a controller board, just imagine it as a virtual Drive you plug instead of your old rotative 3.5" drive.

There are two versions of this device, one uses an USB cable to connect to a PC, the other one uses a SD card to store image disks, with a small LCD screen and buttons to select the image.

SatanDisk and UltraSatan

This device is a complete SD-Card based SCSI harddrive emulation for the 16-32 bit Atari Machine.

The SatanDisk is the older model, supporting only one SD-Card, no hotplug, and quite unreliable. The UltraSatan is the successor, of the SatanDisk: Way faster, totally reliable, supports to SD-Card (the second one can be hot removed and plugged which is practical to exchange data with a pc without having to switch off the atari all the time).

SIO is the name of the expansion interface of the 8 bit Atari machines.

SIO2PC is an interface to connect an Atari to a PC and use it as a virtual disk drive. Exists in homebrew and commercial versions.
