The further they are from the processor, the cheaper they are per unit storage and the slower they become.
Then comes RAM (usually around 16GB on standard computers) and beyond that system storage. The processor is the one that does the compute, the calculations etc and just next to it sits the cache, which is a super fast version of RAM but only available in tiny amounts (up to a couple of hundreds of MB at most). Created for attaching external storage to your computer’s SATA bus, eSATA was a cheap way in its day to get beyond the 60MBps performance of USB 2.0. RAM is needed in order to facilitate data transfer to and from your system storage (can be hard disk drive or solid state drive). It is one of the fundamental pieces of the computing puzzle alongside the processor (or CPU) and classic storage (usually coined as ROM for Read Only Memory). RAM is an acronym for Random- Access Memory. TimeTic makes relatively inexpensive kits of Hynix IC RAM that could seriously bump up your memory capacity. As long as they aren’t glued together, like a Surface Laptop, upgrading your RAM is one of the easiest things you can do to improve the performance of your notebook. MacBooks aren’t the only laptop that you can add extra memory to.
