I wasn't sure if there was an adaptor such as a pcie flash to 2.5 hdd that you can install on Non-Retina Macbook Pros. I currently have a Corsair Force GT 128gb SSD which is good enough for the time being. But later on I'm looking to upgrade my SSD with a large size one, maybe even go Raid 0, but these new PCIE flash base hard drives in the new macs are making me wonder if it's possible with an older computer.
