Costly but cost effective: The case for eMLC. Within the descriptor MLC, there are the sub-categories eMLC and cMLC. In these cases, the "e" stands for enterprise and the "c" for consumer. While still being MLC technology, they represent higher performance and longer life for eMLC and correspondingly lower cost for cMLC. Products that use these technologies can offer very different levels of performance and endurance depending on how they are architected, and results can vary significantly depending on the manufacturer and implementation.

Flash storage technology has become a part of our everyday lives. From the devices in our hands to the servers in data centers, flash memory has become a technology that touches everyone. Still, for all its prevalence, flash technology is only in the early stages of its evolution. There are many different types of flash and choosing the right one for a particular application is critical.

Where flash technology was once considered too expensive for large applications, it is reaching the economic tipping point. IT departments are making the shift from disk to flash, because as the cost of solid state storage goes down the economics of performance justify that shift. However, choosing the right flash solution is still a challenge. What is the right type of flash for your needs? Each variety of flash has its own set of nuances, pros and cons based on its configuration within the hardware and pre-destined performance when manufactured.

In this slideshow, Violin Memory discusses the differences in performance benefits of each flavor of flash starting from the fundamental properties of the chips themselves to the controller and configuration within the array. Learn why this all matters and what happens when different ingredients are blended together.
