Hi, to start off, I'm not tech-savvy but I have read up on what paging is and how it works. But still, something makes me wonder about how the Macbook Air 2010 works as fast as most computers with higher memory. So, correct me if I'm wrong, but page ins are pages stored and accessed directly in the RAM itself, page outs are pages stored in the hard disk and then transferred back to RAM to be accessed, which makes the application slower to initiate, right? Basically, virtual memory is like an auxiliary to RAM, and since back then, conventional hard disks are way slower than SSDs, does that mean that with the amazingly speedy new SSDs that are installed in MBAs makes the page outs as quick as accessing an application directly through RAM? Apologies for the ignorance!!
