“Does this laptop have one or two hard drive bays? Or another form of mass storage? I see that this laptop comes with a 1 Tb hard disk drive, but I was wondering if I could supplement (not replace) this hard drive with an SSD. So, does this laptop have one or two drive bays? Would this computer allow me to put in any secondary form of storage, such as a 128 Gb SDXC card, and use it as a secondary drive? As a note, I am aware that I could probably replace the optical drive with a SSD, but I don't consider it an option as I will be using the optical drive.”
