I really wouldn't say the life span is short, it will last you a good few years without any issues. There are some do's and don't though when running a SSD. Typically you will disable defrag on the drive as this will shorten the life span, however on Windows 7 it will automatically disable defrag on the drive as soon as it detect that you have a SSD installed. Also you NEVER run benchmark tests on a SSD, this also has a adverse effect on the lifespan. Some guys want to see how great their read / write speeds are and end up killing the drive in no time because of these benchmarks.
You get special brackets for SSD's and it fits perfectly into a normal drive bay. Some drives come with these brackets whilst my OCZ didn't so I had to buy one but I think it was like R30.
Hope that helps
