What is SSD and how is it different from HDD?

First and foremost, we need to understand that when we compare SSD and HDD, we’re not trying to find a winner because this is not a competition. Both SSD and HDD have different advantages and disadvantages. Today, we’ll take a look at what these advantages and disadvantages are for SSD and HDD, and how to choose the most suitable option for the user’s needs.


What is SSD?

SSD stands for Solid State Drive. It is a storage device that functions similarly to an HDD in storing data, but SSDs use memory units in the form of Flash Memory Chips, which operate similarly to Flash Drives or Thumb Drives but are faster and more stable.

Advantages and Disadvantages of SSD 

    • Advantages 

SSDs have higher performance than HDDs, read and write speeds are much faster. It also has a small size, so it saves space and doesn’t take up much space in the case. Importantly, it is also resistant to shock. and saves more energy than HDDs. 

    • Disadvantages

SSDs are more expensive compared to HDDs and they also have a shorter lifespan.

What is HDD?

HDD stands for Hard Disk Drive, a device used for data storage. It typically consists of magnetic disks or platters that spin, a design that many people may be familiar with. This type of disk has been in use for over 60 years, since around 1956.

Advantages and Disadvantages of HDD

    •  Advantages

HDDs have a longer lifespan compared to SSDs. Another significant advantage is the price. When comparing SSDs and HDDs of the same capacity, HDDs are generally more affordable.

    •  Disadvantages

The operation of HDDs relies on spinning disks, making them susceptible to mechanical failures if mishandled. HDDs are also slower in terms of read and write speeds compared to SSDs. They are not as suitable for use as the main drive for booting the system or running games due to their slower performance.

HDD and SSD: How do they differ?

Now, let’s address the question of how SSDs and HDDs differ. There are several factors that determine the distinctions between these two types of drives. Generally known is that SSDs are more expensive and offer less storage space, but their data transfer performance may be up to ten times faster. On the other hand, HDDs, which operate more slowly, have the advantage of being much cheaper. Let’s explore the remaining factors one by one.

SSD and HDD are suitable for which type of work?

SSD is suitable for: because it can access data faster than HDD, it is suitable for use as a main drive. Usage that emphasises quick access to files. They boot up faster and speed up application performance

HDD is suitable for: the highlight is the price and value for use. HDD is therefore suitable for use that emphasises value for data storage. Storage of large volumes of data or storing data in the form of backup, backing up various data. That is one of the reasons why many people consider HDD to be the best in terms of price per GB.

1. Speed

Superior speed. This is the main reason why people turn to choosing SSD because when measuring only speed, SSD definitely wins, even though HDD has developed a lot. But there is still a limit to the speed of the disk’s rotation. This means that SSDs that do not use spinning disks are not subject to this restriction. and will always have a faster read/write speed than HDD.

When delving into details and looking at the numbers, the difference in speed becomes clearer. For example, HDDs that are expensive and at the top of the market will have an average maximum rotation speed of around 7200 rpm and the transmission speed of data throughput is approximately 150-200MBps, all of which may be slower than in the actual use. Compare that to SSDs, which have an average data transfer speed of up to 500 MBps. From these figures, it is clear that when it comes to speed, SSD is ahead of HDD.

2. Durability/Stability

The design of SSD parts differs from HDD in that there are no rotating or moving parts. This difference makes SSDs superior in terms of stability, durability, and quietness during operation. Especially when working on a mobile device like a laptop. There is a chance that the device will fall and be damaged. 

The operation of an SSD is to read/write data in memory cells in blocks. in a way that reduces the chance of errors while writing, whereas HDDs need to write memory in a long, chronological manner. As more and more information becomes available, accessing files will become slower and slower. and errors occur more easily. SSDs have no limitations in this regard. Because SSD data storage follows a pattern that allows for quick access to files, both the durability of the chip and the stability are quite superior.

3. Lifespan

When talking about lifespan, HDD is considered to be much better than SSD. That’s because SSDs work by repeatedly writing and deleting data, which is written and then erased on the cell, and this cycle goes on and on. There will come a time when the drive will wear out due to heavy use. Think of our mobile phone batteries that deteriorate because of more charging cycles. Therefore, at a certain point, the SSD itself deteriorates until it reaches the end of its lifespan. Even if we take good care of our drives or have different SSD technologies available, the average lifespan of an SSD will only be approximately 5-6 years.

HDDs work by rotating the disks. As long as the physical characteristics of the hardware are preserved, and it can still spin, it means that the disk can continue to work. If the disk can continue to work and rotate it may last up to 10-15 years without any problems. Overall, HDD is considered to have a longer lifespan than SSD.

4. Power Consumption

SSDs, which can read/write data faster, consume less power compared to HDDs that require continuous disk spinning at around 7,200 rotations per minute. SSDs do not require continuous power consumption of that magnitude. The power consumption of SSDs is in the form of short bursts, and they stop when not in use. Therefore, in terms of power consumption, SSDs may waste slightly less energy.
However, for the average home computer user who plays games, watches movies, and uses the internet, the difference in energy consumption between the two types is almost negligible. The real impact is seen when you are a large business owner with a network of thousands of computers with large-scale server installations using HDDs. In such cases, you will start to notice significant differences in electricity costs, and using SSDs will prove to be much more cost-effective.

5. Gaming

After comparing the pros and cons of SSDs and HDDs, let’s focus on gamers. Which type should gamers choose? Which one is better?

– SSDs load games faster, transfer data quicker, and operate up to 35-100 times faster than HDDs.
– SSDs have better performance in reading, writing, and processing data compared to HDDs.
– Newer SSD models often use PCIe interfaces, which are faster than SATA III drives.

While the difference may not seem significant, SSDs generally improve overall gaming performance, loading games faster. For gamers who want to play games more swiftly and avoid long loading times, SSDs are worth the investment despite being slightly pricier. They offer a smoother gaming experience, making the wait time negligible.
Because what most gamers expect is speed and stability in their gaming experience, it’s a compelling reason to opt for SSDs over HDDs.

Which type of SSD hosting is good?

    • Shared SSD Web Hosting

Normally, shared hosting is slower than other types of web hosting, but when combined with SSD, it will be faster. Importantly, the price is not too high, making it suitable for small businesses and small websites, although there may be a large number of visitors.

    • SSD VPS Hosting

For those who are using VPS hosting, it means they have realized that shared hosting is not suitable or “insufficient” for future use. This implies that customers’ websites may be of medium to large size, with a lot of data. Besides speed, customers may also want stability, ensuring that the website does not go down frequently, causing business opportunities to be lost. SSD VPS hosting is therefore a suitable option for you.

Summary: choosing between SSD and HDD

When asked which is better between SSD and HDD, the answer remains the same—it depends on what features customers are looking for. If they are seeking fast data read and write speeds, then SSD is the way to go. However, if they prioritize affordability and decent specs, then HDD is a good enough option for everyday use without weighing too heavily on the budget.
