This is what I read regarding Search Indexing with SSD (unfortunately I don't have a link to the article):
"Disabling search indexing: the intention behind this is to eliminate unnecessary writing to the disk, and it is also less useful for an SSD, because the SSD is so fast (and small) that searching it even without an index is fast. I can't personally comment on whether or not these are legitimate concerns, because I have never used search indexing in any system.
Another reason to disable search indexing (and this also applies to system restore) is that their usage burns up a little bit of disk space, and causes some background CPU load. If their products are stored on the SSD, that's a waste of valuable space, and if they're stored on a magnetic disk, it may cause a lot of unexpected seeks. Also, I don't know if its possible to customize where these files are stored at all."
