I recently purchased a Dell Inspiron 13Z 5323 laptop for one of my daughters. It has a 500 GB HDD which is rather slow, but it also has an mSATA port which is currently empty. I plan to purchase an mSATA drive to speed it up, and was wondering what is the best size to get. The two choices seem to be 32 GB and 64 GB. If there won't be much speed boost going from 32 GB to 64 GB, then I'd rather save the money and get the cheaper one. Does anyone know if 32 GB is all that's needed for a caching drive?
