SSD vs HDD which is best? A hard disk drive (HDD) is a type of storage system that accesses data using mechanical platters and a moving read/write head. A solid state drive (SSD) is a newer, faster kind of storage system that stores data on memory chips that are immediately available.
Learn about the variations between HDDs and SSDs, as well as the different type factors and how they compare in terms of ability, speed, and strength.
Comparing capability and cost isn’t the only factor to consider when selecting storage. The type of storage your machine uses has an effect on its performance, as well as its power consumption and reliability. The two key storage choices to consider are solid state drives (SSDs) and hard disk drives (HDDs), and it’s important to understand the right use for both and how they compare side by side.
What is a hard disk drive (HDD)?
A hard disk drive (HDD) is a computer’s internal data storage unit. It includes spinning disks on which data is magnetically stored. The HDD is fitted with an arm that includes many “heads” (transducers) that read and write data to the disk. Through an LP record (hard disk) and a needle on an arm, it functions similarly to a turntable record player (transducers). To access various data, the arm pushes the heads over the surface of the disk.
HDDs are known as legacy technologies, which means they have been around longer than SSDs. They are usually less costly and more convenient for storing years of images and recordings, as well as business archives. They come in two sizes: 2.5 inch (commonly found in laptops) and 3.5 inch (desktop computers).
What is a solid-state drive (SSD)?
Solid-state drives (SSDs) derive their name from the fact that they don’t have any moving components. All data is stored in integrated circuits in an SSD. This distinction from HDDs has a number of consequences, particularly in terms of size and efficiency. Without the need for a spinning disk, SSDs can be as thin as a stick of gum (the M.2 type factor) or even a postage stamp. Their ability (the amount of data they can store) varies, making them ideal for smaller devices like slim notebooks, convertibles, and 2 in 1s. Furthermore, since users do not have to wait for platter rotation to begin, SSDs significantly minimize access time.
SSD vs. HDD: Which is Faster?
SSDs are becoming increasingly common due to their speed. SSDs outperform HDDs around the board because they rely on electrical circuits rather than physical moving parts. This results in quicker loading times and less pauses when opening applications or executing heavy programming activities. A standard Intel SSD (Intel® SSD 760p Series) with a middle-of-the-road 512 GB volume provides up to 10x faster read speeds and up to 20x faster write speeds than a midrange HDD (such as Seagate 2 TB Barracuda* 5400 RPM 128 MB Cache SATA* 6.0 Gb/s 2.5″ laptop internal hard drive ST2000LM015), which only offers data transmission speeds of up to 140 MB/s.
SSD vs. HDD head-to-head analysis.
SSDs for computers are available in capacities ranging from 120 GB to 4 TB, while HDDs are available in capacities ranging from 250 GB to 14 TB. HDDs outperform SSDs in terms of cost per capacity, but as SSD prices fall, this would become less of a differentiator for HDDs.
The word “reliability” refers to whether data is stored properly and in an uncorrupted environment. SSDs are more accurate than HDDs in general, which is due to the absence of moving components. SSDs aren’t disturbed by vibration or associated thermal problems because they don’t shift.

As a result, HDDs are perfect for holding a huge amount of large files, making them ideal for storing images, videos, and games.
Previously, SSDs were not capable of such massive capacities, but due to technological advancements, SSDs with terabytes of capacity are now available. However, this comes at an expense, and broad SDDs are often prohibitively costly.
If you have the option, get a smaller SSD, maybe 160GB–256GB, to keep programs like your operating system, which benefit from the SSD’s faster performance, and then use an HDD to store other files where speed isn’t as essential.
SSD vs. HDD in terms of cost
The price gap between an SSD and an HDD is the first thing you’ll find when deciding between the two. Traditional hard drives are usually more costly per gigabyte than SSDs.
It’s important to note, though, that some SSDs are more costly than others. Older SATA III SSDs are less costly than M2 and PCIe SSDs, and certain SATA III SSDs aren’t any more expensive than a conventional hard drive because the technology has been around for a while. For assistance in locating the best SSD deals, see our best cheap SSD deals map.
HDDs are the way to go if you want the most capacity for the least amount of revenue. Traditional HDDs are now comparatively inexpensive to manufacture thanks to improved manufacturing practices, making them more available.
Big HDDs are available for very cheap rates, so if you’re storing sensitive data on them, you can read customer feedback and comments on their durability.

Other factors to remember when choosing between an SSD and a hard drive
When deciding whether to purchase an SSD or an HDD, there are a few other factors to remember. SSDs, for example, are more durable than hard drives and they don’t have any rotating components, making them a safer option for notebooks and other personal devices.
Since SSDs use less power than HDDs, laptops with SSDs can have longer battery lives – but this will vary depending on the kind of SSD you have and what you use it for.
So, which is better for you: an SSD or a hard drive? While SSDs are quicker, more stable, and use less power, HDDs are less costly, particularly in larger capacities.
As previously stated, if you have the opportunity, it might be worthwhile to get a smaller SSD for your operating system and applications, as well as a larger HDD for your files. There are also hybrid drives, known as SSHDs, that combine the speed of SSDs with the power of HDDs in a single drive, and are worth considering if you don’t have enough room in your system for multiple hard drives.
