SSD drive??

Does the Dell Inspiron One have an SSD drive??? I bought from Staples and did not do any fancy upgrades - off the shelf. I want to download a neat sounding defragger but am not sure about the ssd drive - I think ssd must be an upgrade. Supposedly win 7 has a built in defragger that is set up to run automatically - but I turn my system off after each use. I will set up manually whether I use the neat sounding download or built in win 7 - need to know if I have ssd drive for the download. According to "how-to-geek" site - if you have Windows with an SSD Drive: Don’t Defrag. Thanks very much.
