This guide should probably mention that TRIM support is not enabled for after-market SSDs under Snow Leopard or Lion. You are relying completely on the SSD chipset's internal garbage collector to tidy up dirty pages and stave off SSD rigor mortis. Luckily, the OtherWorldComputing SSD the author chose has a SandForce chipset with a very good garbage collector unlike say an Intel SSD which doesn't. Whether or not the author was aware of that when selecting this particular drive over any other, the guide fails to provide this explanation to the reader. I've read that the TRIM Support Enabler software will turn on TRIM in Snow Leopard or Lion for after-market SSDs, so Ars might want to check that out and maybe mention it in this guide. http://www.groths.org/?page_id=322 http://www.groths.org/?page_id=322 Likewise an investigation into different SSD firmware updaters is probably warranted. Many firmware updaters for SSD drives I looked into will only run in Windows which can be a real pain considering this is a guide for MacBooks.
