Happy Friday Word of the Day: All-Flash Array An #allflasharray - TopicsExpress



          

Happy Friday Word of the Day: All-Flash Array An #allflasharray is a solid state storage disk system that contains multiple flash memory drives instead of spinning hard disk drives. Flash memory, which has no moving parts, is a type of nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. It is a variation of erasable programmable read-only memory (#EEPROM) which got its name because the memory blocks can be erased in a single action or #flash. A flash array can transfer data to and from solid state drives (SSDs) much faster than #electromechanical disk drives. Although flash is more expensive than spinning disk, the development of multi-level cell (#MLC) flash has lowered the price of #SSDs. MLC flash is slower and less durable than single-level cell (SCL) flash, but companies have developed software that improves its wear levels to the point where MLC is acceptable for enterprise applications. SLC flash still remains the choice for applications with the highest I/O requirements, however.
