Secondary Storage

Secondary Storage

1. Solid State (Solid State drive)

   • Solid State does not have moving parts in it like the HDD.
     • It is used in mobiles because they are more durable
   • Solid State has a faster reading and writing speed.

2. Magnetic (HDD Hard Disk Drive)

   • The hard drive has moving parts so it is not as durable. The disk inside is what stores the data.
     • It would be used when it has to store programs and files and operating systems
       • Magnetic is also slower than Solid State but it is cheaper and stores more data.

3. Optical (CD/DVD/Blu Ray)

   • It uses a laser because the disks are read by them.
