I know you can get IDE-SD card and various forms of compact flash adaptors for the Amiga.
I was wondering what the limitations of IDE and SCSI controllers are with the Amiga? I would guess the low end would be a raw A600 IDE interface, then a A1200 with some fast RAM, then the A4000 IDE controller, and then third party and Commodore SCSI controllers, for transfer speed.
It's a complicated issue, but I was looking at what the max read and write speeds of controllers are, with a view of what is sensible to attempt when hacking SSD drives onto them.
There is a reason for exploring this, in that Amigas with MMUs can use paged hard drive space as fast RAM - in theory, if your controller can handle the speed, you could run MMU friendly apps of huge complexity, at pretty good execution speeds.
Or maybe the controllers themselves are too limited, and a reasonably quick SD card, says 40MB/S, is plenty good enough anyway and there is no point reinventing the wheel.
On the other hand, M-SATA to ZIF PATA convertors are pretty cheap, and it should be possible to hack a ZIF PATA onto an Amiga. Which might be worth it on a real A4000, but I'm a bit doubtful about what else.
An M-Sata to SCSI 50 pin Single ended could give quite a big boost to SCSI equipped Amigas. But haven't seen any kit that does that.
