Carlo,
Can you manually defrag your current disk, then do a bootable copy / clone of it?
Apple Help on Defrag
From the paucity of defraggers for Macs, this seems to be of almost no concern to most people -- unlike on Windows where defragging is a cure-all (placebo) for what ails ya. But

So, how about
:
- Backup (in case defrag causes trouble)
- Defrag
- Clone to new drive
- Install new drive
