Advantages and disadvantages of hard disk drive

A hard disk is a short form of hard disk drive called an HDD. The term hard drive is referred to the actual disks inside of the drive. However, the terms hard disk ad hard drive is seen as referring to the same thing. it is a non-volatile memory hardware device. it is used to retrieve as well as store data permanently on a computer. Here this blog post gives the pros and cons of the hard disk drive to better understand this topic.

Benefits or Advantages of  HDD:

  • HDD has a large storage capacity than other type of computer memory.
  • Its performance is very high.
  • It works faster.
  • Hard disk drive is more reliable than SSD.
  • Very cheap to produce.
  • The HDD is available in variety of size, which you must select based on your needs.
  • The cost of HDD is cheaper than SSD.
  • Fairly fast to access the data.
  • Easily replaced and upgraded.
  • Persistent storage.
  • It is light in weight.
  • It is fixed inside a computer so cannot be lost.
  • Faster than optical disks like DVDs
  • Lower power.
  • Silent operations.
  • Its sizes are very small.
  • It is portable to use.
  • HDD contain a few moving parts inside a walled area.
  • The computer can communicate with them easily.
  • It can store data like text documents, pictures, videos, audio, files, etc.
  • It can also store operating system files as well as all software-related files.
  • Store items can't lose when the computer switches off.
  • Usually fixed inside a computer so can't get lost.

Drawback or Disadvantages of HDD:

  • Relies on moving parts.
  • It is expensive.
  • HDD is slower read write speed than the solid state drive(SSD)
  • The disk surface can be damaged.
  • Heavy power consumption.
  • It is noisy.
  • HDD produces mechanical noise it cause by the rotation of the disc and the movement of the magnetic head.
  • Slower read and write speed than RAM.
  • Because of its moving part, it requires more electricity for operation.
  • Slower to access than a hard disk.
  • The regular head can crash and damage the surface of the disk.
  • It is slower than IAS.
  • If a hard disk crashes and the computer do not work and your data will lose.
  • This disk was inside in computer so it can not easily transfer to another computer.
  • If it eventually fails, the whole computer stops working at the same moment or at that time.


A hard disk drive is good as it can contain a lot of data as is faster than DVDs. It is also easily changed which is good as technology is always changing something new to develop, so this is handy. But one of the biggest disadvantages is that, If it crashes and the computer does not work and your data will lose.
