SSds, on the other hand, are further limited by the speed of the storage bus, such as SATA or USB. The biggest gain is because of higher maximum throughput, which, in the case of RAM drives, are only limited by the speed of the RAM, the data bus, and the processor.

The performance gain is due to multiple factors, including access time, maximum throughput, and type of file system. The read/write speeds of a RAM drive is generally an order of magnitude faster than SSDs – the fastest form of secondary storage available in the market. It is sometimes referred to as a virtual RAM drive or software RAM drive and, is different from a hardware RAM drive that uses RAM chips to create super-fast battery-powered SSDs.

Once you mount a RAM Disk, you would be able to use it as a regular secondary storage drive and even install programs on it. A RAM disk (also called a RAM Drive) is part of a computer’s random access memory that is specifically reserved to be treated as a regular storage drive by the operating system.
