Expert’s Advice, Know The Difference


Good computers today need to have specific features which best match the requirements of the user. One important feature is that concerning Memory. Computer Memory storage technology has come a long way compared to the days when Floppy Disks ruled the storage industry. Next came the Hard Disk Drive Technology which changed the way we look at Computer Memory devices. The technology is still going strong and will continue to do so. As of today, the latest innovation in the world of Storage Memory is Solid State Drive Technology which involves no moving parts in his hardware setup.


Tips & Thought: Difference between ssd and hdd

So, What’s the subtle difference between SSD and HDD Technology? Its rather simple, Hard Disk Drives can store large amounts of Data and can also be easily accessed. They provide cheap storage solutions but have a magnate disk incorporated into the system which makes it susceptible to failure.

In contrast, Solid State Drives have no moving parts and are also known to be faster than HDDs. So, when its SSD vs HDD, SSD is the clear winner in terms of fast and failure-proof data transfer. However, they are new and do not have high storage capacities which is one of the primary most difference between SSD and HDD.


Short Answer: HDD and SSD Explained

The working of a traditional HDD drive is rather simple which involves a rotating magmatic disk. The data is stored permanently even if you switch off the computer system. The SSD also functions the same way, but data is stored in a system of flash memory chips which stores data even if there is no power supply to it.

Hence, they are very fast and reliable but do not come by the cheap. They are very small in size compared to the HDD which gives computer manufacturers the benefit of design flexibility.


SSD vs HDD: Five Rounds

To make a comparison between HDD vs SSD technology, we must further understand what’s incorporated in the technology.


Round One: Let’s get to Know SSD and HDD Technology

What is an SSD?
SSD stands for Solid State Drive Technology which can be thought of an amplified version of a USB drive. Just like that, on a USB flash drive, there are no moving parts involved and in this technology, information or data is stored in miniature sized microchips. Unlike the HDD drive which has moving parts in it, the losses in an SSD are less and hence the data transfer is faster in comparison to the HDD. HDDs take a lot of time to read and write Data with the help of a mechanical moving arm. SSDs make use of a technology called NAND flash memory which is a type of nonvolatile memory which does not erase data even if the power to the system is cut off. This is the basis on which SSD technology functions.


How SSD Drives Work
As stated earlier, an SSD has no mechanical arm instilled in it but rather has a computing brain called as an embedded processor. It controls all the basic read and write functions and can also store cache and clean up unrequired data. The processor forms the heart and soul of the entire SSD system and a good processor is what separates a good SSD drive from the rest. In modern day SSD drives, processors are so fast that a certain SanDisk SSD drive has the capability to reach read and write speeds of almost 1800 MBPS. SSD drives are smaller and faster and certainly are miles ahead when we do a comparison of SSD and HDD technology.


What is an HDD?
Hard Disk Drive technology has been around since forever. The veteran form of storage technology was first introduced to the world in 1956 by IBM. When it comes to SSD vs HDD, the major advantage of HDD technology is that it has the capacity to store vast amounts of data. In today’s scenario, even 1 TB is not enough to satisfy our memory demands and it’s ever growing. Overall another advantage is that HDDs cost a fraction of what an SSD drive costs. This is one of the major difference between SSD and HDD which is the cost per gigabyte. In common practices, an SSD drive costs roughly 5 times that of an HDD drive. Hence, if it is cheap storage solutions you are looking for, then a standard Hard Disk Drive is your answer. Even when it comes to looks, HDD looks the same as an exterior of an SSD drive. While most laptops are available in a 2.5” form factor, and a typical desktop is available in 3.5” form factor, the more space allows laptops and computers to house larger HDDs with higher capacities. In some cases, HDD drives can reach storage capacities of more than 6TB!


How hard drives work
HDDs make use of magnetism to store data. A magnate which basically performs the read and write function floats above a spinning plate to perform the reading and writing operations. Faster the spinning action of the floating plate, faster is the overall performance of the HDD. In most commonly used HDDs, the floating plate can rotate at a speed of 5,400 RPM while some can even reach speeds of up to 15,000 RPM.


Round Two: HDD vs SSD Advantages and Disadvantages

When it comes to discussing the advantages and disadvantages of HDD vs SSD, the results are mixed. Let us find out.


SSD vs HDD: Pricing
It’s rather simple, due to the sophisticated technology incorporated in SSD technology, it is much more expensive to traditional HDD drives when it comes to cost per gigabyte of memory. A traditional 1TB HDD is available in the market for about USD 45 while, an SSD drive for the same capacity will cost you a mind-boggling USD 250. When roughly calculated, it cost 4 cents per gigabyte of HDD memory and almost 25 cents per gigabyte of SSD memory. HDD will continue to be more economical whereas SSDs must evolve further to be available at cheaper rates.

Hence, in the pricing category of our SSD vs HDD battle, HDD clearly beats SSD technology fair and square.


HDD vs SSD: Read and Write Speeds
Here is one category where SSD is head and shoulders above HDD technology. A typical computer with an SSD drive incorporated into it will usually boot in less than a minute and in most cases, within seconds. This is not the case with an HDD drive-equipped PC or laptop. It will require a few minutes to do so. The HDD drive requires those extra minutes to speed up the operating system of the computer which makes it very slow as compared to an SSD powered PC. Hence, a Windows or MAC computer with SSD technology will start faster, load applications faster and most important of all, transfer files at speeds not possible by an HDD powered computer. Such accelerated speeds are something which the modern-day generation requires.

Hence, in the speed category of our SSD vs HDD battle, SSD technology is the clear winner.


SSD vs HDD: Durability
A typical HDD drive has moving elements in its system, hence the wear and tear of the drive is higher. This poses a risk for data to get lost or the entire HDD drive to completely fail.

When it comes to SSDs, there are no moving parts, hence even if there is a major earthquake and your computer is destroyed, the data on your SSD drive is very safe. Most rotating heads in an HHD drive completely halt when the PC is turned off, but operate at crazy RPMs when the system is running. Even the slightest of touches between the parts means that the entire drive could basically get destroyed. Hence, if you are one of the users who are rough on their computer, we recommend you use an SSD drive.

Hence, in the Durability category of our HDD vs SSD battle, SSD technology is more Durable.


HDD vs SSD: Maximum and Common Capacity
In most commercially available SSD drives, the maximum rated capacity is close to about 4 TB which is again very rare to find and come at very high costs. However, the most common capacities are somewhere between 500 GB to 1 TB. Due to pricing concerns, we get 128 GB SSD drives as well for more economical SSD storage solutions.

As we know that HDD has more storage capacity in comparison to SSD technology. HDD drives are available in storage capacities which can go up to 6TB as well. HDD technology hence will provide more value for money as compared to SSD technology.


HDD vs SSD: Fragmentation
As we know that HDD drives have rotating surfaces in them due to which they are best operational when handling large files laid down in the form of adjoining blocks. By this, the drive can begin and conclude its read operation in one continuous motion.

However, when the drive is almost full, files become scattered all around the platter of the HDD disk which makes the drive suffer from a condition called as Fragmentation. However, this has been resolving particularly well in SSD drives especially due to the absence of physical moving elements and because data is literally stored anywhere. Due to this, SSDs are faster than HDD drives.


SSD vs HDD: Form Factors
To accommodate all the physical components within an HDD drive, there are certain limitations up to which it can be shrunk. Hence, the smallest size of an HDD drive is at 2.5” max. SSDs have no such constraints and will continue to get smaller and smaller as the technology progresses. In most laptops, SSDs are manufactured in the 2.5” scale but that is again only for convenience sakes.


HDD vs SSD: Noise
HDD drives are mostly many moving metallic components housed in once compact casing. As the arm of the driver moves back and forth, it is bound to generate sound. In rare cases, banging sounds too can be heard if the assembly is not proper. In contrast, SSD drives are quiet and make no such noise and this because they are non-mechanical devices.


HDD vs SSD: Power
An HDD drive requires extra electricity to spin the floating plate. Since there are rotating mechanical elements involved, the losses are high which makes HDD drives as power hogging devices.

Losses are minimal in SSD drives, if not completely none. A computer system with an SSD drive in it utilizes lesser electricity as compared to a System with HHD drives in it.


SSD vs HDD: Availability
Despite being available in large numbers, HDD drives are slowly being replaced in most high-end modern laptops available in the market. However, most Desktop Computers will house HDD drives and will continue to do so for at least until SSD technology becomes more economical than it is today.


Overall Difference between SSD and HDD technology
HDDs continue to be the most used storage solutions in most systems today as they are cheap and provide more storage as well. However, if you aren’t too keen on the price, SSD drives are better because they are fast, robust and most importantly, future-proof. Hence, SSD drives represent the future whereas HDD drives will continue to be used at least until SSD technology can be made more economical and can provide more storage capacity.


Round Three: SSD VS HDD Comparison

Let us now compare some of the technical aspects when it comes to Differences between HDD and SSD drives.
