The Types of Hard Disk: SATA vs. SSD Vs. NVMe

When you speak of storage on your computer, you’re talking about the hard disk. They are the place where the majority of the data that you have on your computer is kept including OS files which regulate your computer, to the vital document you need to work on that you will not lose to the game you play when you’re done with your day to chill. All of this is stored in your computer’s hard disk which is why you should ensure you purchase the correct type of hard drive for what you’re doing.

There are three types of HDDs: SATA, SSD and NVMe. This article will help you be able to learn about each kind along with their advantages and disadvantages. If you’re considering building or buying a new computer or upgrading your existing one, this article will assist you in selecting one of all the others.

What is a Hard Drive and why should I have it?

Hard drives are the device which stores your information. It is common to hear the phrase “hard drive” abbreviated to “HDD.” There are many reasons to purchase one of these:

You’re out of the space on your HDD and require a larger one.

You’re noticing that it takes a long time open files and export big files, such as videos

You’re building a brand new PC from scratch

Whatever the circumstance, knowing the reasons you’re looking for or need an upgrade will help you determine what you’re looking to purchase and what you need. Once you’ve figured it out, you’re now able to learn more about the various types of drives as well as the differences between them.

SATA Hard Drive

In 2003, SATA (or Serial Advanced Technology Attachment) was the standard interface for all laptop and desktop hard drives. They are often referred to by the name of SATA used hard drives, however they’re actually rotary drives that have spinning platters and an ejector that writes data to sequential sections on every platter. SATA drives can be extremely speedy when compared to their predecessors that are PATA hard drives. PATA hard drive. They can write data to disks using an interface speed of 6 Gb/s, and an average speed of 600 MB/s.

A single drive could be anywhere from 500 GB to 16 TB, and can be purchased at a lower price than other types of drive that are discussed here. They are a good choice when you require lots of storage at a reasonable price, and do not require a high volume of write or read speeds. They also are susceptible to sudden and violent motion because there are moving components in every drive, making them unsuitable for laptops.


Low cost

Larger sizes for high-end disks


Not recommended for laptops.

Requires regular de-fragmentation

SSD Hard Drive

SSD means Solid State Drive. These disks do not contain moving components. Instead, all data is stored in the non-volatile memory of flash. This means that there’s not any needle to move in order to read or write data , and they’re significantly quicker over SATA drives. It’s hard to determine an exact speed as it differs by the type of manufacturer and design and form factor, however even the slower drives can be compared in performance to SATA drives.

The drawback is that SSD drives are more expensive and aren’t available in as large a variety of sizes. SSD drives can range from 120 GB up to 2 TB and cost about 4 to 5 times the cost of an SATA hard drive similar in size. Because there aren’t any moving parts, SSD drives are also much more durable. There are forms of storage designed specifically for laptops. This makes them perfect to store data on the go.



More durable, particularly for laptops.


Costlier than SATA drives

Lower disk sizes

NVMe Hard Drive

The speeds of NVMe drives can be as high as an interface speed of 32 Gb/s and a throughput of 3.9 Gb/s. This can be extremely beneficial for any task that requires a large amount of data transfer through the disk, such as gaming or editing video in high-resolution.

For as efficient as it gets however, there are some limitations for NVMes. They are, for one, only accessible on desktop computers and they are expensive. The majority of BIOS do not support booting with NVMe currently. There’s still a possibility of getting one that does, however, it could mean having to replace the entire motherboard.


The most efficient disk type that is available


The price is extremely high.

Only available for desktop computers.

It may be necessary to replace the main board to gain the full benefit

What is the best choice? SATA, SSD or NVMe

There are numerous factors to consider when choosing between various components. It is important to select what best meets your needs in terms of technical, capacity and budget needs. Here are some suggestions that can help. Even though they aren’t appropriate for all situations, you should be able to use them in planning your next PC design.

It is worth considering an SATA drive if:

  • You will require a lot of storage space
  • Are you on the brink of a budget
  • Do you require a universal used hard disk for sale
  • You may want to think about using an SSD drive if:
  • Are you considering upgrading your laptop?
  • Need storage that is fast under 2TB?
  • You may benefit from an NVMe drive in the following scenarios:
  • Are you building a top-end gaming or workstation?

Do not have a budget limit

Are you developing a server which will host a large-scale storage application

It’s important to note that you’re not restricted to purchasing just one hard disk. Computers are able to allow multiple at a time. The performance you desire from it is contingent on where you store your files. A typical option for computers that produce video, is to make use of more powerful drives like one with an SSD or NVMe for running video rendering programs (Camtasia, Adobe Premier, etc.) and then to transfer the completed video to a lower-cost or bigger SATA drive.

Keep advancing your knowledge and abilities.

After you’ve taken an in-depth look at the most common kinds of hard drives as well as their functions, you should feel confident about making an informed choice. Consider carefully the motives behind replacing your drive, how much space you’ll need, and the amount you are able to spend. When you’ve done that, and apply the information you’ve learned, the buying experience will be much more enjoyable.
