currently quite a bit more expensive than hard disks. However, the use of flash
memory instead of disks makes them much lighter and faster than hard disks. SSDs are primarily utilized
in portable computers, making them lighter and more efficient. Some computers combine the two storage
technologies, using the SSD for the most accessed data (such as the operating system) while using the hard
disk for data that is accessed less frequently. As with any technology, Moore’s Law is driving up capacity
and speed and lowering prices of solid-state drives, which will allow them to proliferate in the years to
come
