How Each Type Works And What It Means For You


Are you running out of storage space lately?

Or perhaps your hard disk slowed to a crawl? Or are you simply looking to experience optimal computer performance? Well, if you endure these three problems on your computer, it may be time for a hardware upgrade.

But should you go for a cheaper hard disk drive or a faster SSD? A drive is a drive, right? Not at all. This brief article will go through all the notable differences between HDDs and SSDs in terms of capacity, cost, lifespan, and what it means for you and your computer.

SSD vs. HDD: What’s The Difference? 

The primary and most significant difference between a hard disk drive (HDD) and a solid-state drive (SSD) is actually how data is stored and accessed. While the HDD is the conventional storage device that uses mechanical spinning platters and a moving head to access data, SDDs are faster, newer drives that store data on instantly accessible memory chips.

  • An enclosure contains a series of platters concealed by a ferromagnetic coating in an HDD. Here, the direction of the magnetization represents the individual bits. Data is written and then read by a fast-moving head, similar to how vinyl albums work. And because all of these pieces are mechanical, the hard disk is usually the slowest and most fragile component of every computer. 

  • On the other hand, SDDs are newer storage disks that store data on flash memory, consisting of individual memory cells storing bits that are instantly accessible by the controller.

Why Are SSDs Better For Laptops? 

So, suppose you currently have an older version laptop that starts to get slow and sluggish because it works on an HDD and consider making the switch to an SSD. In that case, you should know that SSDs are often the better solution for laptops simply because they are non-mechanical.

In addition, SSDs require less power, which, of course, translates to better battery life. Nowadays, while lower-priced laptops still come with traditional HDDs, most mid-range to high-end laptops come with an SSD for a reason. 

Furthermore, while HDDs have moving parts, SSDs are 100% shock-resistant. So, if you accidentally drop your laptop while the read/write head of the HDD is in motion, it could result in data failure. This can’t happen with SSDs.

In the end, there are also “hybrid” laptops that have both drive types inside them. In a hybrid laptop, the OS, apps, and the most-utilized files are installed on an SSD, while all other data sits on an HDD, which is typically larger and cheaper. In fact, using your SSD to run your operating system is a fantastic way to increase your laptop’s speed and performance.

Just like most other markets, the market for flash storage is volatile and varies based on current supply and demand. Nevertheless, although SSDs are much cheaper than they used to be, there’s still a considerable price difference between the two. While a 1 TB HDD costs roughly $70, a 1 TB internal SSD costs somewhere around $150.

If you’re concerned about how much data you can store on each type of drive, don’t worry, as there are no differences in storage capacity at all. You can get SSDs and HDDs in similar sizes, from as small as 128 GB up to 50 TB or more. However, keep in mind that larger SSDs are truly expensive.

For the moment, if you need to free up some space on your drive instantly, you can format your hard drive, whether it’s internal or external, no matter if it’s an SSD or HDD.

While there’s truth in the fact that SSD cells have a limited lifespan, this isn’t really an issue today. In fact, the myths surrounding SSD life spans are based on assumptions from the 90s and early 00s.

Theoretically, the more data is written to a cell, the faster it can wear out. A present SSD cell can handle around 3,000 write cycles, which doesn’t sound like much at first. However, thanks to the principle of wear leveling, the SSD spreads write processes evenly across all cells to minimize cell cessation and extend the lifespan of the SSD.

Furthermore, modern-day SSDs come with spare cells that replace dead cells. This is called bad block management; it’s the reason why the larger the SSD is, the longer its lifespan.

So, if you’re still unsure whether an HDD or SSD is the best fit for your machine, let’s review how both stack up against each other. SSDs are faster, more compact, quieter, more durable, and consume way less energy. On the other hand, HDDs are more price-friendly and may offer easier data recovery in the event of damage.

As long as the price isn’t your determining factor, SSDs come clearly out on top, mainly since modern SSDs are just as reliable as HDDs.

Artificial Intelligence in the 4th Industrial Revolution


Artificial intelligence is providing disruptive changes in the 4th industrial revolution (Industry 4.0) by increasing interconnectivity and smart automation.

Industry 4.0 is revolutionizing the way companies manufacture, improve and distribute their products. 

What Makes Artificial Intelligence Unique?

Artificial intelligence (AI) makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks.

It allows computers to think and behave like humans, but at much faster speeds and with much more processing power than the human brain can produce.

AI offers advantages of new and innovative services, and the potential to improve scale, speed and accuracy.

There are 3 types of artificial intelligence:

  • Artificial narrow intelligence (ANI), which has a narrow range of abilities.

  • Artificial general intelligence (AGI), which is on par with human capabilities.

  • Artificial superintelligence (ASI), which is more capable than a human.

Artificial intelligence can also be classified as weak or strong. 

Weak AI refers to systems that are programmed to accomplish a wide range of problems but operate within a predetermined or pre-defined range of functions. Strong AI, on the other hand, refers to machines that exhibit human intelligence.

Artificial intelligence has several subsets:

Most AI examples that you hear about today – from chess-playing computers to self-driving cars – rely heavily on deep learning and natural language processing.

What is the Fourth Industrial Revolution?

4th_Industrial_Revolution.jpeg

The Fourth Industrial Revolution is the current and developing environment in which disruptive technologies and trends such as the Internet of Things (IoT), robotics, virtual reality (VR) and artificial intelligence (AI) are changing the way modern people live and work. The integration of these technologies into manufacturing practices is known as Industry 4.0. 

The first industrial revolution used water and steam power to mechanize production.

The second used electric power to create mass production.

The third used electronics and information technology to automate production.

The fourth Industrial revolution is characterized by a fusion of technologies that is blurring the lines between the physical, digital, and biological spheres, with rising emerging technologies, as real AI, Narrow AI/ML/DL, robotics, automation, materials science, energy storage, the Internet of Things, autonomous vehicles, 3-D printing, nanotechnology, biotechnology, neurotechnology, cognitive technology, and quantum computing. It implies radical disruptions to everything, industries, jobs, works, technologies, and old human conditions. In its scale, scope, complexity, and impact, the AI transformation will be unlike anything humankind has experienced before.

The Role of Artificial Intelligence in the 4th Industrial Revolution

Artificial intelligence is making companies make the best use of practical experience, even displacing traditional labor and becoming the productive factor itself. 

It offers entirely new paths towards growth for manufacturing, service, and other industries, reshaping the world economy and bringing new opportunities for our societal development.

As AI begins to impact the workforce and automation replaces some existing skills, we’re seeing an increased need for emotional intelligence, creativity, and critical thinking.

Zvika Krieger, co-leader of the World Economic Forum’s Center for the Fourth Industrial Revolution.

Deploying AI requires a kind of reboot in the way companies think about privacy and security, As data becomes the currency of our digital lives, companies must ensure the privacy and security of customer information.

Businesses will need to ensure they have the right mix of skills in their workforce to keep pace with changing technology.
