2.5 on bare ide a1200:
toshiba 6G, 10G :-D
ibm travelstar 10G :-D
all works wery well (travelstar is slightly noisy than toshiba)
i havel also good experience with 2.5 540mb IBM/aplle rebranded drive from powerbook (runs great in cd32 + sx-1)
one old 2.5 170mb IBM drive is too slow to boot in a1200 and after reset its always stop and spinup again, so booting isnt possible wit that damn old {bleep}
-------------
two 1G IBM scsi drives (50pin) on A3000T scsi internal (plus cdrom) and it was also very good investment (knock knock)
