I was having a bunch of trouble installing Win 7, and had to go back through setup, delete the partitions, and let it reinstall 7. I had to do it several times, and I'm the paranoid type. Would it have put a lot of wear on the SSD? I know multiple reading and writing wears them out, and wanted some piece of mind that I didn't already do something bad. Thanks.

It shouldn't have a really bad effect on the SSD lifespan, you have several rewrites before deterioration. Just don't keep doing it every day.
