Difference Between SSD and HDD | A Complete Guide

Buyers while purchasing computers have hardly any choice to make when it comes to storage. The best they can do to, expand memory is buying an ultra portable device also known as solid state drive. Along with SSD, every laptop also has Hard Disk Drive (HDD). Hence it depends on the user that to which device they would like to configure the system.

However, before you set up your system with any of the storage devices, it is important to understand what they are and how are they different from each other. In this article, I will discuss the difference between SSD and HHD in this article. But before starting this discussion, I want to tell something about this storage.

What is HDD?

The hard drive is a traditional storage system available in almost all the computer systems. The information remains stored even after you switch off the computer. The drive is a metal plate that has a magnetic coating over it and can be used for storing data.

What is SSD?

SSD renders almost the same function as that of the hard drive, but the only difference is data is stored in interconnected flash memory chips, and it can be retained even when the power supply is switched off. Users can either get the chips installed on the system motherboard, PCI express or in a box that is sized, shaped and wired to the laptop appropriately. The flash memory chips are much faster and reliable but are considerably expensive when compared with USB thumb.

Here I’ve pointed out the difference between SSD and HHD

Difference Between SSD and HHD


SSD is comparatively expensive in comparison to HDD. While 1TB internal hard drive of 2.5 inches can be purchased at USD 50, similar SDD starts at USD 220. HDD being a traditional storage system shall be available at economical costs shortly, while SDD shall continue to charge extra prices over the budget.


This is something where SSD is excelling. It does not take a minute for SSD-equipped PC to boot, while hard drive requires some time. Thus laptops installed with SSD boots faster and also run applications at a much more quickly rate. It is fun to use in schools and professional workplaces, enabling users to wind up with work much before the deadline.


As hard drivers have rotatory recording surface, it works well with huge files stored on it. The drive can start and end the whole reading process continuously without causing any disruption. However, when the hard drive begins to fill up it might lead to disk fragmentation. In the case of SSD, such fragmentation does not occur, and it happens mainly because of lack of physical read head.


SSD with no moving parts attached to it keeps your data safe no matter what. So it does not matter if you drop down your laptop or the system is shaken, your data shall remain protected. However, if you are using a system with a hard disk, there are chances that you lose the data in case of damage to the system. Hence if you use your system roughly, then it is recommended to opt for SSD and experience utmost comfort regarding durability.


While Hard drives have been a part of traditional laptop and systems, SDD is becoming a part of the recently launched laptops in the market. It is for sure that the internal hard drives are not going to fade out for more than 100 years from now, and meanwhile, SDD shall develop its market with almost all the laptops based on the new drives.


The mechanical devices are supposed to make more noises while carrying out functions in comparison to the non-mechanical ones. Thus systems with hard drives shall emit sounds while the drive is spinning or reading, but this is not the case with SSD. Users can experience a noise free experience while using laptops based on these drives.

Short Summary of this Difference

If we compare both the products overall then, hard drives are much ahead of SSD regarding price, capacity, and availability. But if we talk about aspects like speed, factor, noise, fragmentation then SSD tears apart the hard drive and excels in capturing the heart of customers.

Which disk drive is the right option for you?

Downloaders: For users who are fond of collecting videos and need enough space at low prices, they can for the hard disk. The drive can be purchased at reasonable prices, enabling them to save data as per their convenience. Graphic artists and professionals who require storage space to keep their stuff, even for them HD is a much feasible option than SSD.

Budget constraints: Customers who have set budget constraints and cannot afford to spend a hefty amount on disk space, can probably opt for HD drives. SSD are too expensive and is not an affordable option for budget buyers.

General users: Users, who are fond of doing some downloads and storing it to their local drives, would require a hard drive on their system. However, if you are among the users who are convenient streaming online, can get an SSD installed in their system and have a good experience exploring the videos.

Security: Users who keep traveling from one place to another, and are not much sure about the safety of their systems shall undoubtedly require an SSD. An SSD based system is not going to fall asleep when you just violently shut it down to rush to a place. This is one of the essential features to look for if you have a hectic job which requires you to keep running from one location to another.

Speedy work: If you are among the users who want to get every work done with speed and pace, then SSD is probably the best option for you. However, before you pick up this option make sure to check if you are ready to spend some extra pounds buying the disk drive.


The facts mentioned above are evident that both the disk drives in spite of rendering the same sort of functions differ in various other aspects. Hence it is important for customers to take a wise decision and then choose a drive, which is suitable to their requirement and can also help them accomplish their objectives.
