Read this article with an in-depth review and comparison of the top two data storages SSD vs HDD to select the best option per your need:
Whenever a person performs some activity on the system, it requires memory, which is called the storage of the system.
Storage is the most crucial element in the process because it keeps track of all the tasks/activities that occurred, and also it makes spaces in memory for the incoming inputs.
A system works on various types of memory which are further divided into more subheadings like the memory that can be overwritten or the memory that cannot be overwritten.
There are various types of memory and some of them are explained in this tutorial.
The system is equipped with two types of storage:
Internal Storage: It is the storage of the system, which specifies the memory and space that can be used by the system to store applications and other data on the system.
External Storage: It is the storage that is added externally and can be used to store data other than the system, for example, a thumb drive.

Computer Memory Measurement:
The memory in computers is measured in bits, and then there are even further higher data units to measure them.
Given below is the list to convert them accordingly:
- 1 byte = 8 bits
- 1 kilobyte (K / Kb) = 2^10 bytes = 1,024 bytes
- 1 megabyte (M / MB) = 2^20 bytes = 1,048,576 bytes
- 1 gigabyte (G / GB) = 2^30 bytes = 1,073,741,824 bytes
- 1 terabyte (T / TB) = 2^40 bytes = 1,099,511,627,776 bytes
- 1 petabyte (P / PB) = 2^50 bytes = 1,125,899,906,842,624 bytes
- 1 exabyte (E / EB) = 2^60 bytes = 1,152,921,504,606,846,976 bytes
In this article, we would talk about two data storages (HDD and SSD) that can be used both internally and externally. We will also compare them and contrast their uses, post which, you can decide which one suits best for your interest and which one is better: SSD or HDD.

HDD stands for Hard Disk Drive. They are devices that are used to store data, actions, and other forms of information. They provide the storage service in the system and keep the memory of actions performed in the system.
History And Advancements
The history of hard disks and data storage devices dates back to 1956 when the first hard disk was invented. IBM developed the hard disk and named it RAMC 350 (Random Access Method Control). It had a storage capacity of 3.75 megabytes.
The hard disk was equivalent to two refrigerators placed horizontally touching each other, whereas the size of the present hard disk is equivalent to the size of a novel. Nowadays the HDDs have advanced rapidly and they come with various unimaginable features.
The features are enlisted below:
- Now HDDs come along with the feature of secured cryptic firmware which encrypts user’s data against any malicious threats.
- Many manufacturers have started using helium sealed HDDs as it exerts lesser drag and increases the drive lifespan.
- The manufacturers are planning to develop Heat Assistant based Magnetic Recording. The heat enables the magnetic recording of data easier, therefore; the creators are counting on this technology to develop a stable prototype.

The hard disk is the most important component of a system. All the actions and data are stored on hard disks. Without hard disks, you won’t be able to boot up the system, download any files, or play any games on the computer. Hard disks are the memory devices in your system which store all your necessary data and inputs.
Preferred Uses Of HDD
- Stocking up Data: The HDDs are the best choice if you want to download data and stack it up because they are cheaper and hence provide more memory than SSDs at the same price.
- Editors: The Editors have to maintain and keep all samples’ records, which easily fill up their space, so they use HDDs as they provide more space to store data.

SSD stands for Solid State Drives. These are the new revolution in storage devices, as they have faster functionality and uses flash memory technology to transfer data.
History And Facts
After the introduction of hard disks, the world looked at the device that can store data, and thus, it created a rush to make advancements in the storage devices. The hard disks require a battery slot to be operated, so all the agencies sought an alternative to this solution, which led to the introduction of SSDs in 1991.
The world’s first SSD was first shipped in 1991 by the company San Disk. Also, it had a memory of 20 MB and was priced around $1000. ($50/MB). The SSDs were comparatively faster than SSDs and contained the battery slots.
With the introduction of laptops, the need for efficient ways to save battery rose. Soon, the entire world was looking for ways to save battery. Then came the revolution in the storage device termed as SSDs, which contained a power source that saved the battery of the system.
Preferred Uses Of SSDs
- Gamers: Gamers keep looking for data storage to make their games function without lag. This results in amazing gameplay and experience.
- Corporates: Corporates need to finish their tasks to the deadlines, and in such cases, SSDs are the best and most suitable device to be used in their laptops.

SSD or HDD: Explore Difference
The differences between the two storage devices can be clear from the below section.
While comparing SSD vs HDD based on pricing, we found SSDs much more expensive than HDDs. The average price for a 1TB SSD is around USD 93-95, whereas the average price for a 1TB HDD is around USD 55-58. The HDDs are comparatively cheaper and affordable than SSDs due to their mechanical structure and composition.
On the basis of storage capacity in SSD vs HDD, SSDs have the maximum capacity of around 2 TB, which allows you to store data and files in your system, whereas the HDDs have comparatively higher memory than SSDs and can store up to 16TB of files. For those using the SSD cloud, data storage can also be an option.
But if the person wishes to access the data and keep it in any physical device, then HDD is the perfect thing.
When SSD and HDD are compared based on processing speed, the SSDs uses flash memory for accessing data stored in the memory, which makes it faster and efficient. Also, in SSDs, the data is stored in a continuous manner. It begins from one end to another, leading to continuous storage and easy storage of data, whereas in HDDs, the data is stored in platters.
Therefore, it is fragmented and then stored in the memory, which sometimes raises the problem of accessing memory, resulting in hard accessing of data.
Whenever there is a big file, it is stored in HDDs in fragmented or pieces form in the device and when the system wants to access these files again, then it has to look through all the platters for these fragments hence resulting in slower functioning. This is the main reason that gamers prefer HDD over SSD.
#4) Reliability and Durability
When HDD vs SSD is compared on the basis of their durability, SSDs are completely packed. They do not have any spaces between their components, resulting in a completely safe and durability of device. Whereas there is some gap between the components of HDDs which makes it a matter of concern while being used.
#5) Power and Lifespan
Talking about the lifespan of SSD vs HDD, SSDs are equipped with their power source, making them efficient for laptops, whereas the HDDs require a power source to be accessed and operated.
Now when we are talking about the life span of these devices, we first need to understand that how do they work.
The HDDs write data on platters, which are then rewritten when the data is erased or some other data is overwritten making it easier to use, whereas in SSDs the data is stored in the form of the flash memory of flash signals which are erased and rewritten over the continuous usage of the drive.
The HDD stores data in platters, which can make it wear out over time, whereas SSDs will remain new and efficient; therefore, SSDs are better choices in lifespan.
Which Is Better For Gaming: SSD or HDD
Gaming is the most important reason which makes the computer upgrade industry prosper. The gamers look for devices that are fast and efficient and are compatible with heavy graphic drivers. So, SSD is the better choice for gamers as it allows faster processing and makes the game function without any lag or glitch.
