I have always maxed out my RAM to speed up my computer. The primary reason for doing this was to minimize the use of Swap files. Swap files are used to transfer data not currently being used from RAM to a disk drive so that the system does not run out of functional memory. When the data is again needed, it has to be read from the disk drive back into RAM, a time-consuming process. Getting a system with as much RAM as possible has always been essential to avoiding this speed bottleneck. For example, on my Late 2011 MBP, I have installed the unsupported, but possible, 16 GB of RAM. Do I use it? Yes, my system originally came with 4 GB of RAM. Right now, running OS X 10.10.4 with only Outlook, Safari, Activity Monitor and my normal Menu Bar programs running in the background. I am using 4.85 GB of RAM. During a typical work day when I have 5-7 more apps running, I frequently jump up to 9 to 14 GB depending on what I am doing. The OS X version has also had an influence. MBPr’s and MBA’s are now using PCIe SSD RAM. These have much higher functional throughput than SATA even SATA SSD’s. This considerably widens the Swap file bottleneck. My first question, is this fast enough that the amount of RAM is really a mute point when it comes to speed? Second, there is not much talk among Apple SSD users about SSD writes, but others discuss that SSD longevity is significantly reduced by the amount of writes on an SSD. Swap files are constantly being written, read and erased. Is the amount of RAM on a system now a factor in determining a system’s SSD longevity? Or, is this a non-issue too?
