I find the Samsung software pretty annoying, so for WIndows 7 and 8 systems, I just run it once to make sure everything is optimized, and search for firmware updates, and then I uninstall it. On Windows XP I leave it running for manual TRIM operations. One annoying thing about the software is that if my laptop doesn't have an internet connection (which is common because I travel a lot) the Samsung software will have pop-up messages telling me an update is available. If I hooked up to the internet to download the update, it would say there are no updates.
In any case, I would suggest downloading and installing the latest magician software, and have it check the status of the drive, upgrade any firmware, check that system settings are optimized, and run an SSD optimize. Then unisntall the software, and repeat again in several months.
