sparse images fragment
One reason not to use sparse images is that they heavily fragment on your drive as they need to 'grow'. This isn't the case with Panther's file-vaulted home directories because when a user logs out the OS can automatically defragment and claim unused space in the file-vaulted image. I doubt this would happen if you follow this tip.

Is this true? Why wouldn't Mac OS X clean up the fragmented image once it was dismounted, like it will any other file?

defrag only works in Panther on files < 20MB in size. The idea is that a file of 20MB or less is probably going to fit into an available continuous block of space so the whole thing gets rewritten. Computers and drives are fast enough now that most people won't see the overhead from the extra work. |
