I have (so far) only encountered SCSI drives oriented "normally"
or on their side edges. (though I suspect no differences between
them and their IDE counterparts).
Most manufacturers describe allowed mounting orientations in their
data sheets for the drives.

There is one thing that is not typical about the CP3044 and that is the
relative placement of the 40pin header and the power connector. The 1520
uses an adapter board to connect the floppy and HD to the motherboard.
This adapter board fixes the relative location of the floppy header, HD
header, and HD power connectors. The HD is actually installed inverted
in the computer. (I wonder if that orientation is acceptable for all drives.) The CP3044 aligns the power pins with the row
of header pins
furthest from the disk platters. Newer drives seem to align the power
connector pins with the mid-line between the header pins.
