Optical storage


  • Non-volatile storage - data will not be lost after the computer is turned off and lost power
  • Optical disks are solid - hard to break because of no moving parts
  • Easy to transport
  • Cost of optical storage is cheap - but it depends on the capacity of the device
  • sometimes it can be re-used


  • Transfering speed is not as fast as magnetical
  • Some older computers do not read the disk
  • sometimes it cannot be re-used


Optical storage is a very cheap and reliable storage as it is very durable and very easy to transport however it is slower than other storage's and some computers might not be able to read the disks.
