Difference between a floppy disk and hard disk

The main difference between a floppy disk and a hard disk is that the floppy disk is an outdated technology that has only a few kilobytes of storing capacity but they were portable whereas the hard disk is the main memory of the computer which makes it non-portable and also the hard disk has more storage capacity and they can go up to few terabytes of memory. The hard disk drive is faster to access as compared to the floppy disk and also they are less susceptible to damage than the floppy disk

Difference between a floppy disk and hard disk

FLOPPY DISKHARD DISK
The floppy disk is a magnetic disk that is molded to a thin circular plastic diskThe hard disk is a magnetic disk also called a platter and are made from aluminum
Floppy disk was secondary storage devices they were used many years ago and are now non-existentThe hard disk is the primary storage devices of computer and existent till date although Solid-state drive are giving competition to Hard disk drive they are costlier than Hard disk drive
The surface on which the data is stored are exposedThe surface on which the data is stored are coated with magnetic oxide
The floppy disk has a very low storage capacity it can only store few kilobytes of memoryThe hard disk drive has a high storage capacity and it can store up to terabytes of memory
The floppy disk is more susceptible to damage The hard disk is less susceptible to damage 
The floppy disk is cheaper The hard disk is costlier than the floppy disk
The data access from the floppy disk by the CPU was slow The data access from the hard disk by the CPU is fast as they are the main memory devices
The floppy disk is the size of a CD cassette and is easily portableThe hard disk is the size of a walkman and is fixed into computers therefore are non-portable
The floppy disk faced a high-security threat from computer virusThe hard disk has less security threat as computer now can easily perform a virus scan on main memory
The data can be damaged easily as it interacted more frequently with dust and heatThe data can not be damaged easily as they are tightly sealed inside the computer case
The floppy disk is housed inside a plastic jacket The hard disk is housed inside the platter
The data recorded on the floppy disk are done through the magnetic dots on the spots of the trackThe data recorded as magnetic spots on tracks that are present in a concentric circle on the disk surface
The floppy disk was mainly used as a secondary device like keeping a copy of the data in form of some backupsThe hard disk is primary memory and hence they are used by the operating system to function properly storing various variable of the programs by the operating system
The floppy disk is also known as a removal type of storage this means it can be moved to any location easilyThe hard disk is also known as a fixed type of storage this means it cannot be moved
Both the side of the disk can be used to store the data The uppermost side and lowermost side of the disk cannot be used to store the data
The fourth generation of the computer has completely eliminated the floppy disk reader that were present in the previous generation of computerThe fourth generation of the computer has completely eliminated the floppy disk reader that were present in the previous generation of computer. The fourth generation of the computer has the hard disk drive slots on the computer as the main memory
