SSD vs HDD: Which Should You Buy?

The past few decades have completely transformed technology and made it much more accessible. These changes have revolutionised our daily habits, from online shopping to financial services. Some of the reason for these advancements has been to speed up processes to make things more convenient.

An area of technology that has been affected by these changes is data storage and capabilities of personal computers and smaller devices like laptops. The components responsible for these functions are storage drives and discs. The most common storage types are solid-state drives (SSDs) and hard disc drives (HDDs), which function differently and should be used based on their intended purpose.

Many aspects are different between an SSD and an HDD that you should be aware of before making a purchase. You will want to know the differences to decide whether you need a new HDD or an SSD upgrade.

Our experts at My Computer Works can assist you with an SSD upgrade in Horsham, West Sussex to get your computer running fast and performing well.


The two main types of computer data storage are SSDs and HDDs. Many modern setups combine the two for a hybrid drive that allows the owner to enjoy the advantages of each, but there are key differences between them that are important to know. Their differences are in storage capacity, speed, performance, reliability, power, and price.

Solid-State Drive

A solid-state drive is newer compared to hard disc drives. SSDs were created in 1978 and have seen many improvements since then. These drives are solid-state and use NAND technology, which means that they store data in integrated circuits instead of spinning discs and do not need a continuous power source (non-volatile) to retain stored data.

Newer machines with SSDs typically have a more modern connection called PCIe (peripheral component interconnect express) for data transfers. This interface for data transfer is much faster than other types, but the type of connection needed depends on the system itself. Solid-state drives are constantly evolving and seeing improvements, so if this is the type of storage your computer has, it may be time for an SSD upgrade to enjoy its advantages further.

Hard Disc Drive

The hard disc drive evolved from a much older machine created in 1956 when you needed large devices for small amounts of data. The HDDs used today are much smaller but inadequate in many areas compared to SSDs. The HDDs we use today feature spinning discs that read and write data using the “heads” (transducers) on the arm attached to the disc, similar to how a record player functions. These drives are also non-volatile but typically use SATA (serial advanced technology attachment) interfaces for data transfers which are inferior to PCIe interfaces.

Advantages and Disadvantages

The difference between an SSD and an HDD is mostly in their performance speeds, but each has pros and cons that make them better for different purposes. An SSD is the best choice for people or companies needing quick operating speeds to access data quickly, whether because of preference or necessity. For example, for a business that has to perform actions for customers or clients rapidly in real-time, an SSD is the best choice because it is much faster than an HDD. An HDD is the best choice for storing “cold” data, which does not always need to be accessed, like large volumes of photos that are only occasionally looked at, not every day. These data storage devices differ in various areas, including capacity, speed, performance, reliability, power, and price.


The main pro of SSDs is that they are smaller but more powerful than an HDD. The flash memory of NAND technology maximises the storage capacity of these drives and speeds up the data recall or transfer because there is no waiting time for discs to start spinning and power up. The performance of SSDs means when multiple servers are involved, the drives get more work done per server resulting in a less overall effort to achieve the same data output as an HDD. The complete list of the pros of an SSD includes the following:

  • Faster, Better Performance
  • Small & Flexible For Smaller Devices (laptops)
  • More Reliable
  • More Durable & Less Chance of Data Corruption
  • More Efficient Data Reduction
  • More Battery Life Since Less Power is Needed
  • Design Produces No Noise

There are a few disadvantages to an SSD, however. These cons include being more expensive than an HDD and having less storage capacity. But these are not deal breakers because, compared to HDDs, the price of SSDs is decreasing faster every year, and the total cost of ownership is lower, so eventually, the price will no longer be a disadvantage for SSDs. Additionally, while the storage capacities of SSDs are smaller on the surface, their data reduction is much more efficient, and the maximisation from NAND technology makes this less of an issue.


While storage capacity is a slight issue with SSDs, HDDs excel in this area. These drives are ideal for the long-term storage of lots of data. The pros of using an HDD include the following:

  • Less Expensive
  • More Storage Space
  • Standardised Structure

The disadvantages of an HDD compared to an SSD are that they require more power, the design produces noise, their mechanical structure makes them less durable, and performance is much slower. The structure of an HDD consists of spinning discs and an arm with components for reading and writing data that can suffer damage when dropping the device or applying external factors (vibrations or thermal). In turn, these events could also lead to data corruption or total data loss. However, regarding data storage versus access, this type of storage is better because of its capacity and price.
