Right... you referred to it as “memory.” I was simply pointing out the mixup in terminology, which is actually quite common.
Memory (Random Access Memory or RAM) is used for caching of programs for quicker access by the processor. Solid state storage is simply a hard drive without spinning disk. I use two 240 GB OCZ Agility 3 SSDs in my gaming desktop and have 12 GB DDR3 RAM (memory).
Okay...all I know is me likee MBP w/R very much....but pricey...
