SSD vs HDD which is better?

Hi Friends,

Today we are going to discuss a very interesting topic of HDD vs SSD hard drives.

A lot of people get confused about which hard drive to be selected while buying a laptop or they don’t even know which hard drive does their laptops have.

So in todays post we will discuss the difference between HDD & SSD hard drive and also which one to be selected.

So first let’s understand the difference between the two..

DefinitionSolid State DriveHard Disk Drive
writing speedFasterSlower
Shock resistantYesNo
Read and Write timeShorterLonger
Fragmentation occursNoYes
Contain mechanical partsNoYes
Produce noiseNoYes

Now hope the above table would have clarified the basic differences. now lets have some more in depth definitions on this.

What is an SSD? 

SSD Definition: An SSD, or solid-state drive, is a type of storage device that contains non-volatile flash memory and is used in place of a hard disc due to its much faster performance.

A Solid State Drive (SSD) is a technology that is very similar to a USB Flash drive or a Thumb Drive. SSDs can be regarded as a new generation of computer storage devices. SSDs employ flash-based memory, which is much faster than mechanical hard discs. Use of an SSD is one of the most effective ways to accelerate your computer

There are various types of Solid State Drives (SSD). Some of the most common ones are:

  • PCIe
  • NVMe
  • M.2 SSD

Advantage of SSD 

There are many benefits of SSD (Solid State Drive). Let’s go through some of the advantages of SSD.

  • Because an SSD contains no moving parts, it requires less power to operate.
  • An SSD provides faster computer boot times, faster data transfer, and greater bandwidth.
  • SSDs come in many sizes, ranging from the size of a stick of gum to 2.5″ form factors.
  • SSDs are lighter because of their smaller size, and their compact design makes them ideal for laptops, tablets, and other small electronic devices.
  • Heat is the leading cause of hard drive failures, and because an SSD lacks such components, it can operate at a lower temperature while providing much higher performance.

What is HDD? 

HDD Definition: A hard disk drive or HDD is a non-volatile data storage device.

Hard disc drives have been around for over 50 years, steadily increasing storage capacity while shrinking in physical size. HDDs are typically installed internally in computers, directly connected to the disc controller on the motherboard. It houses one or more platters inside an air-tight casing. HDDs read and write data using spinning discs or platters.

Application of HDD

There are many benefits of HDD (Hard Disk Drive). Let’s go through some of the advantages of HDD.

  • Computers can easily communicate with HDDs.
  • Hard disc drives (HDDs) are widely available on the market.
  • When a computer is turned off, the data on an HDD is not lost.
  • Hard disc drives have a faster data transfer rate than DVDs and CDs.
  • An HDD is permanently installed inside a computer and thus cannot be lost.
  • When it comes to affordability, HDDs remain the most cost-effective option.
  • Because the raw materials used to manufacture HDDs are inexpensive, the cost of the HDD is relatively low.
  • Text documents, operating system files, software-related files, pictures, videos, audio files, and so on can all be stored on a hard drive.

Which one to use

SSDs, in a nutshell, are faster, more durable, more minor, quieter, and use less energy. HDDs, on the other hand, are less costly and may allow for easier data recovery in the event of a failure. SSDs come out on top if the price isn’t a deciding factor.

Now as you have understood the difference between the two hope you can now decide which one to choose. As we conclude the SSD hard drives are expensive compare to HDD so if you need higher storage capacities with good performance, how will you get that? here is the answer.

A lot of new laptops which are older generation has DVD writer installed which we rarely use. so you can remove that DVD writer & put a SSD caddy or move the original hard drive to caddy and fix the SSD on the primary slot of the motherboard. through this method the operating system will be installed in SSD which can be as low as 128 GB and much cheaper and the secondary hard drive can be used as a data storage drive.
