The problem with an SSD is the maximum read-write cycle barrier. Sooner or later your SSD is simply going to stop working. Not anytime soon, but most builders will include a second hard disk as a storage unit. Put your pictures, music and games on the traditional hard drive, the OS and updates and Office on the SSD.
It’s safer; it keeps the SSD doing what it does best and provides a nice place to put your backup image. If you’re on a laptop you can get an external USB drive.
