The largest advantage to a RAMDisk is the 100-150x transfer speed boost over HDDs and even ~25x over SSDs (goodbye loading screens!). To put things into perspective: 1866MHz RAM has a peak data rate of approximately 15GB/s, so even matched against the world’s fastest consumer-class SSD (or enterprise-class, for that matter), RAM will far-and-away outperform it.Ī RAMDisk offers quite a few unique advantages and disadvantages. The RAM is still volatile, but builds and maintains an index throughout user-defined intervals in use it will write to an index on non-volatile storage to keep data permanently. In the simplest of terms, a RAMDisk is RAM in a hard drive costume. This can be thought of as the RAM pretending to be an incredibly fast hard drive so you can install non-volatile games/programs on it or make it a scratch disk. A RAMDisk is a virtual drive that uses RAM to store information.
