 A non-volatile storage device that stores digitally encoded data  Introduced in 1956  Long-term persistent storage

 An SSD emulates a hard disk drive interface  Flash Memory  Two Types:  SLC  MLC

SLCMLC  Faster  Longer Life Span  Cost more  Less Expensive  Smaller Life Span  Speedy throughput and access times SLC NAND flash MLC NAND flash Random Read 25 µs50 µs Erase 2ms per block Programming 250 µs900 µs
