Storage Devices

Storage Devices

1. Optical

   • Advantages: is very portable, is inexpensive for a small amount of data, is immune to magnetic fields
   • Disadvantages: is not very robust, is slow at transferring data, is expensive for storing large amounts of data

2. Magnetic

   • Advantages: huge storage capacity, cheapest storage, data can be stored for a long period of time
   • Disadvantages: magnetic fields can damage the stored data, not very portable, has mechanical moving parts, is slow to access data

3. Solid state

   • Advantages: is very portable, is robust, is able to access data quickly
   • Disadvantages: are expensive, has a limited amount of erase/write cycles
