256 SSD vs 1TB HDD

Ok I have to reload my OS onto a bigger drive, and I already have sata 1TB drive.
All of this is so I can run FSX faster and more maxed out.
Should I:
-continue with this plan to swap every thing over to the much larger HDD?
-Shell out the money and get the 256gb SSD?
-Or wait till there is a 500gb SSD?
