Are you low on space and thinking about updating your storage? Well, you don’t really have a choice because, in no time, you’re going to feel your device lagging due to all the data overflow anyways. Ultimately slow processing will not only decrease your work productivity but may also cause long-term problems in your device. So updating is a must.
But now comes the real issue. What storage should you choose when there are quite some options to choose from. The main two categories that tend to confuse a buyer are the SDDs and the HDDs. Although they have the same function, certain features significantly differ from one another. Taking a closer look at them will help you better understand what purpose each of these fulfills.
What’s The Difference Between SSD and HDD
Following are some of the major distinctions that separate the two kinds of storage. Knowing what makes them different from one another can help you make a better decision when deciding which of the two you must opt for.
Technology Difference Between SSD and HDD
The primary function of both these devices is the same. Both these devices are designed for the basic function of securely storing multiple files like your documents, music, pictures, and much more so that you can efficiently access them anytime in the future. Change in construction and technology is what leads to a change in their working mechanisms.
In the case of an HDD, which is referred to as the traditional or the old-fashioned version of storage, mechanical platters are used. These platters come with a coating of ferromagnets and it is the direction of the magnetization for each which forms the bits.
After the storage of the information comes the reading of this information. In HDD, this is done using a head that works similar to how music is played in vinyl record albums. Although the head moves pretty fast during this process because this is basically a mechanical process it’s usually the slowest and most fragile part of the computer.
The SSDs, on the other hand, use a comparatively new technology that was introduced roughly after the late 2000s. It uses memory chips to store the data. The memory chips are also called flash memory considering how fast every piece of the stored information is accessible to the user.
The flash memory technology that SSDs uses is nonmechanical. This means it’s not as fragile as the HDDs, in fact, they come with a shock-resistant feature. This means that even if you accidentally drop an SSD, you most likely won’t face the consequence you will suffer when using the HDD.
Speed Difference Between SSD and HDD
The speed difference is where the actual distinction comes between the two. There are precisely two kinds of operations where the speed difference is most apparent. One of these is the sequential read-write operation.
During the sequential read-write operation, we examine how fast the device can copy and paste the data, especially the heavier files like films, etc. For our old school hard drives this process can take somewhere between 30 to 150 MBs per second. This means that if you were to move a movie of 20GB it would take at least two minutes to perform the shifting process.
On the other hand, as mentioned previously an SSD uses non-mechanical flash memory chips. This works much faster than the HDD when it comes to the copying process performing the process at a speed of around 500 MBs. And I’m talking about the most basic SSD’s here.
If we talk about the latest NVME SSD, the speed can go up to a whopping 3000-3500 MBs. So you can copy a 20GB movie in 10 seconds or even less. Isn’t that just amazing?
The second operation is the 4k read-write operation. This is the process of running files on your PC generally while operating the system. You experience this when you move from one app to another or move from one file to another. During these small tasks, the read and write operations are constantly in motion.
The Hard drive can approximately take anywhere between 0.1 to 1.7 MBs for each task. This is much slower when compared to the 50 to 250 MBs per second that the SSD’s take for every 4k read and write operation it performs.
SSD vs HDD Power Consumption Difference
Considering the speed discussion I just had, you might think that more speed comes with more power consumption. But guess what, that’s far from the truth. Despite giving a much better speed performance the SSDs offer reduced power consumption features.
As an example consider the average 512 GB SATA SSD. Despite its high-speed performance when copying data it consumes average power of only 0.075 watts. Due to the reduced power usage, it also helps last the battery life of your PC for a longer time
On the other hand, the conventional hard drive uses an average of 6.8 watts per hour during its processing. This can be too much for your computer’s batteries; it consumes almost 16% of your device’s energy within only an hour.
How to Use SSD and HDD Together In Laptop?
Until now you’ve made your decision and you know which storage is better for you. But wait. What if you wouldn’t have to choose? Isn’t that perfect? You get to keep the best of both. Combining the speed of the SSDs with the massive capacity of the HDD will make your laptop extremely fast in all its operations.
But to combine the two, you need to follow an exact process with precision and understanding. Now the problem is where to find the exact process? Just kidding. Of course, I’ve got every aspect covered for you so keep on reading because I have a step-by-step manual for you to easily understand exactly what it is that you need to do.
First, you need to download a professional app to convert your operating system from the hard drive to the new SSD you are adding. The MiniTool Partition Wizard is a reputable application that can do the job for you. Once the app is installed, launch the app to view the main menu on your screen
Look for your existing Hard drive and select it. Now you will see some options appear on your screen. On the left side a ”Migrate OS to SSD/HD Wizard” option will be visible, click this option.
Now you will see a new pop-up window appear. From these options click Option B. This will copy only those partitions that the system requires. Now select the NEXT option to continue with the process.
This is where you now select the SSD option and then click the Next button to proceed further. Here you will see a warning message that notifies you that all data on the target disk will no longer be available. Select the yes option to allow this process to occur.
Now comes the review phase. Take a good look at all the changes you’ve made before you move further. Once you’re satisfied with the selected option click on the Next button to move further.
Finally, you will now see the finish button on your screen. Click this and then select the applicable option for complete execution of the changes you just made. You’ve successfully installed an SSD along with your existing Hard drive, and you can now enjoy the pros of both these devices on your laptop at the same time.
Difference Between External Hard Drive VS Internal Hard Drive
When looking to add space to your device while making the decision between an SSD and an HDD is tricky to make, there’s another aspect a buyer usually finds confusing. That’s whether one should opt for an external or an internal drive.
The main difference of course as the names indicate is in the connection. One is attached externally via USB etc whereas an internal drive is installed within your device.
To understand which one shall work better for your personal use, you might want to look further into the differences in their functions. Following are some of the key aspects you can consider when comparing the two.
The external hard drives are designed with super fast speed however due to the switching of the interface the process does suffer a slight lag. As compared to this the internal hard drive suffers no switch and lagging and hence due to this direct transfer of information it exhibits faster speed.
This feature is more apparent in some of the best external hard drives for photos. Here you can see how much time the transferring of images can take. Similarly, the process of reviewing these pictures after some time is also much easier with devices having higher transfer speeds.
Both internal and external drives have the same basic mechanics, so there is no major difference inf their reliability based on their construction. However certain external factors may affect this aspect.
Commonly the external drives are openly placed around multiple spaces and hence are more exposed to damage or shocks. On the other hand, internal drives are built inside the laptop and hence remain protected at all times. Therefore they have a lesser chance of internal hard drive failure.
There’s really no fixed statement for this one. For any company or brand, you might find the internal drive being pricier than the external drive whereas vice versa for another brand. So if you’re low on budget and want to prioritize cost minimization, you could always go for either of the cheaper options.
Which is better SSD or HDD?
Generally, SSDs are much faster and more reliable as well. Similarly, these are more reliable due to their shock absorption feature which is why it is considered better amongst the two
Can I replace SSD with HDD on the laptop?
Yes, if you’re looking for a simple way to upgrade your laptop, a swap SSD from HDD can be a great way to revamp your system
What are the disadvantages of an SSD?
Although it’s one of the most popular options for most users looking for improved storage for their PCs, SSDs can be expensive. The high price is the most prominent disadvantage of this device.
Picking the right kind of storage can be tricky especially when there are so many options to choose from. But I’m sure once you go through this article, you’re sure to have all the knowledge you need to make a well-informed decision. Hope you find your best pick!
