All About Solid State Drives (SSD)

Solid state drives for computer systems are old technology–they have been available for over a decade. The earliest solid state drives ( SSDs ) were based on DRAM, the same underlying technology as modern memory, although they were often priced … A single NAND SSD can achieve 10-30K random I/O operations per second (IOPS), while a single SAS disk can achieve perhaps 250 IOPs. For some database operations, such as random reads or writes (e.g
