I have come to accept that I will be replacing SSDs periodically. Either because they're worn out, or because a newer/faster/better technology is available.
A RAM disk is an interesting alternative for sure. The last time I used one was when I did OS/2 development using IBM VisualAge IDE. Which sorely needed it...
Windows doesn't have a driver for one out of the box, but there is a freeware one named ImDisk that looks widely used.
