worst developer ever
I am considering an SSD myself...but I have a LOT of addons, and don't want to have multiple smaller drives. So, it looks like I am goung to have to spend some big bucks to get a high capacity SSD in the not too distant future...
You can store your user-flyable aircraft in a folder on a conventional drive (as long as you link to it in the FSX.cfg) while having everything else on the SSD.
User-flyables are generally loaded only once per flying session anyways (contrary to AI aircraft which got in and out of the Ram all the time).
