Disk upgrades for LC-class machines

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?

Thanks

Yes those computers will only take the smaller drives because of their limited internal space. Have you considered an external scsi drive to ADD to the ones you already have? The only capacity limitations you might run into are at 4 gigs (?)...(or is it a terrabyte...may depend on your OS version). anyway i doubt youre gonna, hit 4 gigs or much less a terrabyte. As far as scsi option you just want straight up normal lil ole SCSI. SCSI-3, 2, wide, fast, generally is only available in the new high end power pc clones which you dont have. you cant even interface the alternate scsi drives with the older computers because of a different plug setup. so just get straight ole SCSI.
