A Solid State Drive (SSD) is a modern storage device. The storage is non-volatile in nature thus it retains data even if the power is off. As the name suggests solid state drive, the drive does not contain any moving mechanical parts like HDD. SSD makes use of flash memory and is capable of accessing […]
