Inception or what? The Falcon SSHing into its own RaSCSI :) I bet I could even enable X forwarding to run modern Linux apps on the Falcon X server :D

Seeing the heatsink: is your Pi overclocked?
I've never achieved more than 800kb/s with my stock Pi3B+ even on a SCSI adapter in a modern PC

@beel1 No just stock clock speed. You're running a Rascsi also I assume? It could be the Micro-SD card, I am using a Sandisk C10 Ultra.

@beel1 I just remembered, on the rascsi wiki it says that the rascsi.service software is single threaded - and the Pi Zero is single core, so it might help.

https://github.com/akuker/RASCSI/wiki/Benchmarks
I suspect that the Pi 0 got higher scores because the RaSCSI software only uses one core. This gives the Pi 0 a slight clock speed advantage

Thats not bad, a little better than the UltraSatan and a tad slower than the IDE interfaces. Guess I need to build the SW and try mine. :)

Looks like I got the BLUESCSI working ok with my STe and ICD adscsi adapter :mrgreen:

It didn't work powered off the SCSI cable or usb port though, had to use the berg connector for it.

@DaveC Nice! Have you run some file transfers to test stability? I find that even if TOS transfers OK, Kobold will show if there are issues.

Here is a good disk error check program by PP:
