you can however use the SD for the location for all your files and music etc - it then allows the SSD
installed to remain as free as possible. Because it slots flush with the chassis this makes a nice internal solution.
In saying that I do believe the 16gig SSD
to be as small as you can get away with, the advantage the SD card has is these are now relatively cheap - I use a NTFS formatted 32 gig one to move all my stuff between laptops (NTFS formatted because I move large images around) works fine - just not so good with OSX!!
