I've got a 4.5gb SCSI drive here that I was using with a CyberStorm PPC card a while back. Works fine and is very fast. This may attach to other CyberStorm models too. Not sure if SCSI 1,2 or 3 - don't really know how to tell, but it's a straight plug in to the CPPC board.

This is an IBM DDRS-34560 (http://www.google.gr/url?sa=t&source=web&cd=1&ved=0CBkQFjAA&url=http%3A%2F%2Fwww.hitachigst.com%2Ftech%2Ftechlib.nsf%2Ftechdocs%2F85256AB8006A31E587256AA400595BA0%2F%24file%2Fddrs_spw.pdf&rct=j&q=ibm%20ddrs-34560&ei=8ZE0Tq6WD8XwsgajndS5Ag&usg=AFQjCNG9oWh_2x2zzJvQ-yv7A-5o0WLI-Q&cad=rja) drive I think.
It's SCSI 3.
Ultra-Wide 68-pin interface.

You are correct - that is the model number. Thanks for your help :)

It seems for the big box ppc, my a1200 ppc has different connector.

Correct :)

The blizzard PPC had a 50 pin SCSI 2 interface while the Cyberstorm PPC (and CS mk3) had the 68 pin (SCSI 3??) interface which was also much faster.

This drive here should work on a 50 pin interface using a cheap adapter from ebay (but with scsi 2 speed).

Might or might not work, some single-ended wide drives misbehave on narrow buses and either need a more expensive adapter with high-byte termination or, if used with the cheap ones, must be placed at the end of the SCSI bus, with their termination and termination power enabled.

Also, it's a bad idea to discuss mechanical interface or speed using the 'SCSI 2' or 'SCSI 3' terms. They're umbrella terms encompassing a host of possible bus specifications/configurations.
Also, quite naturally, SCSI 3 includes SCSI 2 (which in turn includes SCSI 1), save some retired specs. So it's not like they're mutually exclusive.

E.g. the 68 pin connector (mechanical interface) matches the 16bit SCSI (wide) which was already defined in SCSI 2.
And if you use an adapter on an ultra wide drive you just turn it into an ultra narrow drive, so it still falls uniquely under SCSI 3 ('ultra' was not part of SCSI 2).
