Mechanical hard drives can be very fast when reading sequential files, such as copying movies. But when we usually use the operating system, the most common application is reading scattered files, such as operating system startup, opening programs, web browsing cache, etc. Each time we need to read many small files distributed in different locations on the disk. Mechanical hard drives rely on the magnetic head to constantly seek before it can read. It seeks and reads again and again, so a lot of time is spent on seeking and reading scattered small files.

RAM is one of the most core performance metrics of a computer. Too many services, processes, or programs running in the background and foreground can take up a lot of memory (unnecessary and temporary files accumulate over time and take up a significant amount of memory). As a result, our computers may become unresponsive, freeze, or crash, causing frustration and inconvenience. This is where Wise Memory Optimizer comes in.
