Secondary storage

Secondary storage

1. Solid State

   • USB stick
   • Phone
   • It's very durable because it has no moving parts compared to magnetic storage which means it is more efficient and you can rely on it. Also the drive uses microscopic electronic switches to store data
   • The memory chip inside a solid state have a limited amount of the write cycles as a result, it can lead to data loss.

2. Magnetic

   • It has moving parts so if you drop it it can easily break in the inside. Compared to solid state which has no moving parts it is less reliable.
   • Magnetic is more cost effective when you need lots of storage space and it has a larger capacity than solid state.
   • DVD drive
   • Magnetic tape
   • Floppy disk
   • Hard drive

3. Optical

   • It can be easily scratched and damaged which can lead to it not being able to load as fast compared to solid state and magnetic.
   • The optical storage devices are cost effective compared to solid state devices and magnetic devices and it is more portable compared to magnetic and solid state devices
   • A CD
   • Blu-Ray

4. Stores data permanently until you decide to delete it
