SSDs and HDDs?

There are two major types of computing storage(where we save our files) which are SSDs and HDDs. Most of us will usually buy a computer with 1TB HDD, which is usually a wrong choice. In this post, we will discuss some of the factors to consider before opting for SSD or HDD when buying your next PC, you may also see a reason to change your computer's storage to an SSD. So, let's get started.

If you have to choose between a hard disk drive (HDD) and a solid-state drive (SSD), how do you make a decision? Should you choose cheap and large storage capacity over fast and secure?

Read/Write Speed

The reason why most modern computers hang is that hard disk drives have a relatively slower read/write speed compared to what the computer programs needs. HDDs usually have a spinning disk at 5400rpm or 7200rpm; the 7200 rpm being the fastest. A typical 7200rpm HDD will deliver a read/write speed between the ranges of 80-160mbps while a typical SSD will deliver a read/write speed between the ranges of 200-550mbps. This great difference in terms of read/write speed makes SSDs about 300% faster than HDDS.

Safety of Data

Since solid-state drives have no moving parts, your data will more likely be safe in the event your computer suffers a shock such as a fall or hit. On the other hand, hard disk drives have many mechanical parts and utilizes magnetic storage to store and retrieve data. With HDDs, your device is more prone to failure or loss of files when they are stored in a magnetic field or in the case of an accident. So, if you need a computer system, that will offer you less risk of integrity failure or loss of data, then solid-state drives are the way to go.


Of course, the performance and reliability of solid-state drives come at a price. Even the smallest common SSD size of 128GB, which is about 25% of the capacity of many small budget laptops with 500GB hard drives are relatively expensive. For instance, a 500 GB SSD costs more than 500GB HDD at least by a factor of 5.

However, when you consider the benefits of SSD like increased speed, greater storage density, quiet operation, decreased power consumption, data security and greater reliability, then you can agree with us that the extra cost is worthwhile.

Quiet Computing Experience

Since SSDs are non-mechanical, they don’t emit noise. You can’t get this noiseless experience with hard disk drives because the drive platters of HDDs spin and the read arm continuously ticks. Even if you have the fastest hard drives, they still make more noise than the slower ones.

So, What’s the Best Storage for You?

Let’s use this analogy: think of your processor as a car engine, your RAM as the road smoothness (potholes, etc.), and your storage as road traffic; if you have a v8 car engine (good processor), plying on a good road (good ram), your car’s speed will still be impeded if there are many cars on the road. This is the same way too much traffic (work) on the HDDs per time makes that your Core i7, 32G ram computer slow.

Most times, Changing your storage to an SSD will ensure that your PC boots within seconds and makes your computer very much faster.

Once you’ve considered what purpose you want your drive to serve and the price you are willing to pay for it, then it’s much easier to decide from there.

Generally, if you are a heavy multimedia downloader or a small budget computer buyer, a hard disk drive may be fit for your needs, unless you are willing to spend much on getting a larger size SSD. On the other hand, if you are a speed enthusiast, tech-savvy or you just want better performance over storage size capacity, durability over cost, then SSD is the perfect choice for you.

So, whether you need a personal computer for gaming, coding, school, or business, the extra speed of an SSD may be the difference between finishing a project on time and missing a deadline.
