Mac OS X SSD Tweaks
Ok, I have an Intel X-25M 160 GB SSD coming and I’m on a VERY GEEKY mood…so I decided to poke around a little on what could be done to tweak Mac OS X in order to, at least minimize the write amplification problem and also optimize the space used—yes you know the €/MB ratio is high on SSDs. Most of these tweaks, besides providing for a longer lifespan for SSD disks, should improve overall system performance even on an non SSD disk.
