Storage types

• • Solid-state storage uses flash memory to store data.
• • Optical storage - works by reflecting laser lights onto the surface of rotating disks, reading the reflections as 1s or 0s.
• • Magnetic- Mechanical parts move over the disk to read and write data magnetically
• SSD-+ fastest access time, expensive, medium in capacity, portable, durable
• Optical +- low capacity,slowest access speed, cheap cost, poor reliability (not durable) , thin and portable
• Magnetic+- large capacity, cheaper cost (than SSD), not portable as moving parts, slower access speed (but faster than optical)
