PrimoCache (formerly called FancyCache) is a very useful Cache Disk program, developed by Romex Software from China. As opposed to virtual memory, it virtualizes the idle space of physical memory, SSD hard drive, or flash drive on your computer into the cache space of your HDD hard drive, making your computer run faster. In other words, it can store the data that needs to be read frequently in the hard disk into a faster storage device such as physical memory, thus effectively improving the performance of the physical hard drive.

To improve the performance and lifespan of your HDD, you just need to defragment it regularly. While for SSD, to improve the efficiency and keep the peak performance of your SSD, you need to optimize and tweak Windows settings for SSD drives.

File fragmentation on disk significantly slows down the file access (read/write) speed, especially in working environments where source code libraries and compilations are frequently updated. So defragmenting software is one of the common tools that computers must use. There are so many defragmenting programs in the market - commercial, free, or open-source. Among them, Diskeeper and PerfectDisk, both with a long development history and solid technologies, are recognized leaders - any other similar applications pale by comparison.

First of all, you need to know that RAM has a maximum read/write speed of 100 times that of SSD and 200 times that of HDD. Therefore, when the physical memory is large enough, we can use some tools to create a virtual disk partition in the memory to specially store some frequently used programs and files (mainly temporary files generated by operating system or web browser), thus significantly improving the running speed of OS and software, and extending the service life of HDD and SSD.

Solid-state drives (SSD) have obvious advantages than the traditional mechanical hard disk drives (HDD), but do not mistakenly believe that an SSD does not need optimization. However, for the optimization of SSD, many users may just know one optimization setting - a new SSD should be formatted with 4K alignment. In fact, SSD actually has a lot of places that can be optimized for making its speed faster and service life longer.
