I want to buy 2.5" SSD. I dont know about mSata.
1) Recommend to find out what is your laptop model first? Here is how

2) Go to the Lenovo site to find out the laptop specifications or manual.
3) Using google find out the how to replace the laptop HDD, then you know you can switch the HDD with SSD. Even you can open the laptop to see the HDD is sata type or not, because if the laptop does not have the msata header, you can't use the msata tpye SSD, I think most of the laptop will use the sata tpye not the msata type.
4) If you don't know how, can you post the model? and we will try to help you out.
