best solid state drive for macbook pro samsung 840

There is a 24GB mSATA SSD that is listed in the manual, but it could only act as cache memory right? HP product manual doesn't say anything about SSD compatibility for my laptop, they have listed only HDDs (both 7mm & 9mm are compatible it seems), How will I know if SSD can be replaced for the HDD, is it necessary for me to go to the service center and check it out if there is slot & drive can be upgraded? I could find that the connector is Serial-ATA 7-pin for both of them, not sure - just googled it. SSD 840 EVO - 500GB 2.5-inch MZ-7TE500BW | Samsung SSD
