It really depends on the partitioning software.  With the software
supplied with the original Apple SCSI card, you can only create two
partitions (64 MB in total).  With the software supplied with the
high-speed card, you can only create four partitions (128 MB in total).

If you can get a third-party utility which can create more partitions
(or find someone nearby who has the necessary software and can do this
for you) then you can go up to seven partitions (224 MB) with the
original SCSI card, or at least nine (depending on the partitioning
software) with the high-speed card.

You will usually be limited to 11 partitions in total on all drives,
because there are only 11 spare entries in the ProDOS drive table
(assuming a 128k machine, one 5.25" controller and no other disk
drives or standard slot RAM cards).

Nine partitions would be 288 MB, eleven would be 352 MB.

To be able to use more than four partitions with an Apple SCSI card,
you must be running ProDOS-8 2.0.1 or later, which requires an
enhanced IIe.  With earlier versions, you can only get four partitions
if the SCSI card is in slot 5.  If it is in another slot, you will
only be able to access two partitions.
