Netiquette IQ Definition of The Day - Flash Caching

Flash caching is the temporary storage of data on NAND flash memory chips to enable requests for data to be fulfilled with greater speed. In a common scenario, the system stores a temporary copy of the most active data in the flash cache and a permanent copy of the data on a hard disk drive. The goal of flash caching is to store previously requested data as it travels through the network so it can be retrieved quickly when it is needed again. Placing previously requested information in temporary storage, or cache, reduces demand on an enterprise's bandwidth in addition to speeding up access to data. A flash cache is often used in tandem with slower hard disk drives (HDDs) to improve data access times. The form factor of the NAND flash is typically a solid-state drive, a PCI Express (PCIe) card or a DIMM-based flash device installed in a server's memory sockets. Many flash cache appliances have built-in logic that decides what data should be placed in cache so when read requests are received, the appliance can answer them.  =============================== In addition to this blog, I have authored the premiere book on Netiquette, "Netiquette IQ - A Comprehensive Guide to Improve, Enhance and Add Power to Your Email".
