HDD Disadvantages:
1. Slower average speed:
• Different variants of hard disk drives have different read and write speeds—depending on their respective RPM or rotation per minute specification.
• HDD is prone to fragmentation of data because of its rotary recording surface.
2. Higher power consumption:
• Another disadvantage of a hard disk drive is that it consumes more power.
• The storage device basically needs more power input to rotate the metallic platter and move that magnetic read head.
3. Produces noise while in operation:
• The spinning of the metallic platter and the back-and-forth movement of the magnetic read head create mechanical noises while a hard disk drive is in operation.
• Both spin and movement also create subtle vibrations. This is more noticeable during boot or whenever a user is storing large files.
4. Not durable compared to other:
• One great disadvantage of a hard disk drive is that it is more prone to integrity failure or data loss and overall device corruption.
• The movable mechanical parts of an HDD make it physically vulnerable to mechanical damages due to drops and shudder.
• For example, the close spacing between the read head and the metallic platter makes HDD prone to scrapes across the platter as the head grinds the thin magnetic coating.
5. Bulkier form factor:
• Another disadvantage of a hard disk drive is a bulkier form factor.
• There is a limit on how small HDDs can be manufactured because of the need for a rotating metallic platter and a moving read head.
• This makes HDDs not suitable for mobile computing devices such as laptops.
