Advantages+and+Disadvantages+of+Magnetic+storage+devices

=Advantages of Magnetic Storage Devices=

1. Very fast access to data.

2. Data can be read directly from any part of the hard disc.

3. In most of the magnetic storage devices the acces speed is about 1000kb/s

4. Some of the magnetic storage devices are very cheap for example floppy disks.

5. Most of the magnetic storage devices store very large amounts of data.

=Disadvantages of Magnetic storage devices=

1) Data can be altered by magnetic fields, dust, mechnical problems

2) Gradually lose their charge over time - data lost

3) Hard disks eventually fail which stops the computer from working.

4) Regular crashes can damage the surface of the disk, leading to loss of data in that sector.

5) The disk is fixed inside the computer and cannot easily be transferred to another computer.
