I love the PowerPC Macs that I own and have owned but I have a question for the group sort of about the newer Intel Macs since I work at Best Buy and only deal with Intel machines when it comes to Apple products. Is PCIe 2.0 almost as fast as RAM to the point where using the swap or paging out is almost irrelevant? I know when not enough RAM is available that the data will be temporarily written to the HDD which in turn slows down the system drastically. With the use of SATA SSDs and the faster R/W rates, that is probably less of a concern but still likely unless the amount of RAM is sufficient. With each advancement of PCIe, is it likely that actually having separate RAM will no longer be a necessity? Because if the PCIe-based flash storage is just as fast as RAM, then wouldn't using the swap have an almost negligible effect on performance? Thanks in advance for any clarification of this since me looking this up before wasn't making it very clear.
