RAM is a commodity component and therefore relatively inexpensive, yet it possesses outstanding performance characteristics and lacks the shortcomings that are attributed to Flash devices. RAM is an excellent technology to leverage for accelerating I/O performance and delivers a very high benefit-to-cost ratio across the entire storage architecture.
High-Speed Caching is critical for maintaining application performance since RAM is many orders of magnitude faster than the fastest Flash technologies and it resides as close to the CPU as possible. It is the fastest storage component in the architecture, delivering a 3-5x performance boost to applications and freeing up application servers to perform other tasks. It also extends the life of traditional storage components by minimizing the stress experienced from disk thrashing.
