I want to upgrade the internal disks on an LC and a Performa 475, both of which have the "pizza box" case. I am told that I can only put 1/3 height drives (0.75 inch thick) in these machines, and that 1/2 height (1.0 inch thick) drives won't fit. Is this true?
On a related issue, I am not very knowledgeable about SCSI disks, so I want to make sure that what I buy will work in these machines. Are there any issues of absolute storage capacity to worry about (e.g in DOS-land, there is the infamous "528 mb barrier" for IDE drives without BIOS upgrades)? What is the implication of SCSI vs SCSI-2 vs SCSI-3 vs Wide SCSI vs Fast SCSI etc? Which one(s) will work in my machines and which one(s) won't? Why?
