The benefits of having the operating system and applications on SSD seem remarkable.
The only downside is the cost of the drives, or more specifically, the cost per GB.
So, I'm considering getting a 160GB Intel SSD Drive as the boot drive for my Mac Book Pro, and then using a 500GB USB Drive to store photos, movies and music.
The downside of this approach is that I have a separate piece of hardware to deal with.
Got me thinking - I wonder when the form factor of notebooks will put flash memory onto the motherboard to hold the Operating System, Applications and swap, and have the existing 2.5" bay be used for a traditional drive or SSD to store the user's data.
Think I might wait for that form factor.
