A Hardrive is a device found that stores and retrieves (computer) data. It consist of two discs that are magneticly coated. The data is 'written' on to the discs and then is 'read' when you want to retrieve it.
A SSD does the same job however it is smaller, thinner, lighter and has no moving parts, however this does mean that SSDs are more expesive than Hardrives. As time goes on the prices of SSD are falling and because of this it will soon be at the almost the same price.
