Storage Devices

1. Solid State

   • Advantages
     • Has no moving parts making it durable
     • It is energy efficient
     • High read and write speed
     • much faster than magnetic
     • Significantly faster data transfer rates (some drives claim 92% faster
     • More reliable long term storage
     • reduced power consumption
   • Disadvantages
     • Compared to magnetic not cost effective
     • Due to the unique file system structure of an SSD, data extraction can be an extremely difficult and lengthy process
     • Because the data recovery process is so difficult and takes so long, it can be quite expensive
   • Examples
     • Phones, tablets and gaming PCs/ laptops
     • Found in USB sticks
     • Uses microchips to store data instead of magnetised disks and do not contain any moving parts.

2. Magnetic

   • Advantages
     • Cost effective
     • High capacity
     • Cost effective due to having a larger capacity than solid state.
     • Relatively cheap per unit of storage. Fast access and retrieval times compared to other storage devices
   • Disadvantages
     • Lesss durable as Solid State
     • not durable due to moving parts
     • can be easily damaged , will slow down and eventually break over time
     • slower access than solid state drives
   • Examples
     • PCs , desktops, laptops, gaming consoles and computers

3. Optical

   • Advantages
     • Cheap
     • Potable
     • Can be used in a variety of devices
     • can hold a lot more data than a standard DVD meaning it can store movies with better picture and sound quality
   • Disadvantages
     • Low Capacity
     • Not durable can be scratched very easily
     • More expensive than DVDs and requires a blue ray player also can lose data if scrached
     • has a limited capacity
   • Examples
     • CDs, DVDs, and blue-ray
