In my experience of several PB 500 series machines, they were supplied with IBM SCSI drives, which I have found to be entirely satisfactory in capacities up to 1.1 or 1.2GB. I have also used Seagate SCSI drives in 500s. What prompts your question? A 2.5-in 5400rpm 19mm SCSI HDD is just a drive. The installed System and the PB's controller have more effect on the usefulness of drives than other factors.
There were adapter cards that allowed the use of IDE drives in place of SCSI drives, with the advantages of obtainability, cheapness and so on, but unless the landfills are full of them, they seem not to have been widely used.
