HFS is slow (very slow when you get larger sized volumes, because each
logical block gets mapped to several physical blocks.) The max volume
size for HFS is 2GB (not 4), which is like having 64K logical blocks each
being 32KB in size, whereas ProDOS only allows the 512 byte size. (64K *
32K = 2GB, 64K * 1/2K = 32MB)
