SSD vs HDD – What’s The Difference And Which Is Better?

SSD vs HDD – You must know what’s the difference between SSD and HDD and which is better for your needs from the Coding compiler. Generally, we might think that a hard drive is a hard drive, right? But that’s not correct.

A hard drive can be an HDD or SSD and there’s plenty of differences between SSDs and HDDs. We have listed all the tested differences between SSD and HDD storage to help you figure out which is the best option for you.

Until a few years back, PC buyers didn’t have much choice about what kind of storage came on their laptop or desktop. If you bought an ultraportable, it probably came with a solid-state drive (SSD) as the primary disk (C: on Windows, Macintosh HD on a Mac). Some other computers came with a standard hard disk (HDD). 

HDD Vs SSD – The Explanation

Now, you want to configure your system with an HDD or SSD or, in some cases, both. We explain the comprehensive explanation of HDD and SSD and the differences between SSD and HDD and we will walk you through the advantages and disadvantages of both to help you decide which one is best for your needs. Let’s have a look.

What is HDD?

HDD – Hard Disk Drive. The traditional spinning hard drive is the basic non-volatile storage medium on a computer. The saved information does not “go away” when you turn off the system.

A hard drive is essentially a metal plate with a magnetic cover that stores your data, whether it’s last century weather reports, a high-definition copy of the Star Wars trilogy, or your music collection. A read/write head on one arm enters information as its propellers rotate.

What is SSD?

SSD – Solid-state Drive. An SSD functionally does everything a hard drive does, but data is stored on interconnected flash memory chips that retain information even when no power is present.

The chips can be permanently installed in the motherboard (as in some small laptops or ultrabooks), in a PCI Express card (in some high-end stations) or in a box that has size, shape, and wiring to insert into the hard drive from a laptop or desktop (common in all). 

These flash memory chips are of a different type than that used in USB slots and are typically faster and more reliable. SSDs are consequently more expensive than USBs with the same capacities.

SSD Vs HDD – The History of HDDs and SSDs

To the clear understanding of HDDs and SSDs, we need to dig into the history. Let’s have a look at the history of Hard-disk drive and the history of Solid-state drive.

The History of HDD

Hard drive technology is relatively old in terms of computational history. There are well-known photos of the old 1956 IBM 350 RAMAC that used 50 24 ”wide drives to house an impressive 3.75MB of space. This is, of course, the average size of a 128Kbps MP3 file, in the physical space that could hold two commercial refrigerators. 

The IBM 350 was only used by government and industrial users and was outdated by 1969. Isn’t progress wonderful? The standardized form of the 5.25 ”hard drive in the 1980s, with 3.5” desktop and 2.5 ”notebook drives coming out later. 


The internal cable interface has changed from serial to IDE (now often called Parallel ATA or PATA) to SCSI to Serial ATA (SATA) over the years, but each does essentially the same thing: connect the hard drive to the PC motherboard to process the data. 

SATA Interfaces

Today’s 2.5 ”and 3.5” drives primarily use SATA interfaces (at least on most PCs and Macs), although some fast SSDs use the PCIe interface. Capacities have grown from multiple megabytes to multiple terabytes, more than a million in increase. Current 3.5 ”drives have capacities as high as 10TB, with 2.5” drives reaching 4TB.

The History of SSD

The SSD has a shorter history. There has always been a fixation with immobile storage since the beginning of personal computing, with technologies like bubble memory (yes, that’s what it’s called) and dying in the seventies and eighties. 

Current flash memory is the logical extension of the same idea and does not require constant power to retain the data you store. The first primary disks we knew as SSDs began during the rise of netbooks in the late 2000s. In 2007, the OLPC XO-1 used a 1GB SSD, and the Asus Eee PC 700 used a 2GB SSD as primary storage. 

SSD Chips

The SSD chips in low-end Eee PC drives and the XO-1 were permanently soldered on the motherboard. As netbooks, ultrabooks, and other ultraportable laptops became more capable, the capacities of SSDs increased and, over time, they became standardized to a size of 2.5 ”. So you could take a 2.5 ”hard drive out of your laptop or desktop and replace it with an SSD. 

SATA Version

Other factors emerged, such as the mSATA Mini PCIe SSD, M.2 SSD in SATA and PCIe versions, and DIMM-like Flash Storage on MacBook Air and MacBook Pro, but today many SSDs still use the 2.5 ”size. 

Latest SSDs with More TeraByte Storage Capacity

Its capacity currently reaches 4TB, but a 16TB version was recently released by Samsung for business devices such as servers. But today many SSDs still use the 2.5 ”size. Its capacity currently reaches 4TB, but a 16TB version was recently released by Samsung for business devices such as servers. 

SSD Vs HDD – Advantages and Disadvantages of SSDs and HDD

Both SSDs and hard drives do the same job: They boot your system and store your personal applications and files. But each type of storage has its own set of functions. 

How do they distinguish themselves and why get one instead of the other?

SSD Vs HDD – Price Comparison

SSDs are more expensive than hard drives in dollar-per-gigabyte terms. A 1TB 2.5 ”internal hard drive costs about $ 50, but as of this writing, an SSD of the same capacity and form factor cost $ 220. 

That translates to 5 cents per gigabyte for the hard drive and 22 cents per gigabyte for the SSD. Since hard drives use older, more established technology, they will remain inexpensive in the near future. Those extra SSD coins will dramatically increase your budget.

SSD Vs HDD – Storage Capacity Comparison

Although SSDs top out at 4TB, they are still very rare and expensive. You are more likely to find 500GB and 1TB drives as primary disks in systems. While 500GB is considered a staple for a hard drive in 2018, price concerns may bring it down to 128GB for lower-cost systems. 

Multimedia users will require even more, with 1TB and 4TB drives common in high-end systems. Basically, the more storage capacity, the more things you can save on your PC. Cloud-based storage may be suitable for storing files you plan to share between your phone, tablet, and PC, but local storage is less expensive, and you only have to buy it once.

SSD Vs HDD – Speed Comparison

This is where SSDs shine. An SSD-equipped PC will wake up in less than a minute, and often in seconds. A hard drive takes time to reach operating specifications and will continue slower than an SSD during normal use. 

A PC or Mac with an SSD wakes up faster, launches and runs apps faster, and transfers files faster. Whether for leisure, school, or work, extra speed could be the difference between finishing on time and failing.

SSD Vs HDD – Fragmentation Comparison

Due to their rotary recording surfaces, hard drives work best with larger files that are supported by contiguous blocks. In this way, the disk head can start and end its reading in one continuous motion. 

When hard drives start to fill up, large files can become scattered around the disk, causing the disk to suffer from what is called fragmentation. 

While the algorithm read/write has improved to the point that the effect is minimized, hard drives are still prone to fragmentation. SSDs can’t because of the lack of a physical read head means that data can be stored anywhere. Thus, SSDs are inherently faster.

SSD Vs HDD – Durability Comparison 

An SSD has no moving parts, so it’s more likely to keep your data safe in the event that you drop your backpack or your system is shaken by an earthquake while in operation. 

Most hard drives park their redheads when the system is turned off, but they fly over the physical drive a few nanometers away when they are running. Plus, even hand brakes have limits. If you are tough on your computers, we recommend an SSD.

SSD Vs HDD – Availability Comparison 

Hard drives are more abundant in budgets and older systems, but SSDs are becoming more prevalent on recent laptops. 

That said, product listings from Western Digital, Toshiba, Seagate, Samsung to Hitachi continue to be biased in favor of hard drive models over SSDs. 

For PCs and Macs, the internal drives won’t go away completely, at least for years to come. SSD models are growing in numbers – just look at the number of thin laptops with 256 and 512GB SSDs installed instead of hard drives.

SSD Vs HDD – Form Factors Comparison

Because hard drives depend on turntables, there is a limit to their manufacturing size. There was an initiative to make them shorter, 1.8 ”, but they stalled at 320GB, as the manufacturers of phablets and smartphones settled on flash memory for their primary storage. 

SSDs have no such limitation, so they will continue to shrink as time passes. SSDs are available in 2.5 ”laptop sizes, but that’s for convenience only. As laptops become thinner and tablets become the primary platforms for web browsing, you will see growth in the adoption of SSDs.

SSD Vs HDD – Noise Comparison

Even the quietest hard drive will emit a bit of noise when in use, from rotating cymbals or the front-to-back reading arm, particularly if you’re on a system that has been hit or has been improperly installed in a metal system. Faster hard drives will make more noise than slower ones. SSDs do not make any noise as they are not mechanical.

SSD Vs HDD – General Comparison

Hard drives gain in price, capacity, and availability. SSDs work best if speed, form factor resistance, noise, or fragmentation (technically part of speed) are important factors to you. If it wasn’t for the price and the capacity issues, the SSD would win hands down.

As far as longevity is concerned, although it is true that SSDs wear out over time (each cell in a flash memory bank can be written and erased a limited number of times), thanks to TRIM command technology that dynamically optimizes these read/write cycles with an SSD. 

If you are really concerned, there are several tools that monitor the SMART status of your hard drive or SSD, and they will let you know if you are nearing the end of the drive space. 

Possible exceptions are high-end multimedia users like video editors who constantly read and write data, but those users will need larger capacities for their hard drives. These will eventually wear out from constant use as they use physical recording methods.

SSD Vs HDD – Which is Better For You?

SSD Vs HDD – Until reading this section you might be thinking which is better for you and which is the right storage and which one fits for your needs. Let’s have a look at the useful key points, we break it down for you:

HDDs Are Better For Enthusiastic Multimedia Users

  • Enthusiastic multimedia users and severe download managers: Video collectors need their space, and you can only have 4TB of space at no cost with hard drives.
  • Budget buyers: The same. Quite cheap space. SSDs are very expensive for PC buyers at $ 500.
  • Graphic Arts and Engineering Professionals: Photo and video editors run out of storage with overuse. Replacing a 1TB hard drive will be cheaper than replacing a 500GB SSD.
  • General users: Too obvious. People who prefer to download their media files locally will still need a larger capacity hard drive. But if you stream your music and videos online, then buying a smaller SSD for the same amount will give you a better experience.

SSDs Are Better For Graphic Arts and Engineering Professionals

  • Road Warriors: People who put their laptops in their bags without discrimination will want the extra security of an SSD. That laptop may not be asleep when you violently turn it off to reach the next flight. This also includes those who work in the field, such as public workers and university researchers.
  • Demons of Speed: If you need solutions now, spend those extra pennies for quick starts and app launches. Supplement with a storage SSD or hard drive if you need the extra space.
  • Professionals in graphic arts and engineering: Yes, I know I said they need hard drives, but the speed of an SSD could make the difference between completing two proposals for your client and completing five. These users are prime candidates for dual disk systems.
  • Audio engineers and musicians: If you’re recording music, you don’t want the scratchy sound of a hard drive intruding. Better opt for a quieter SSD.

What’s New in HDD & SSD Space – Hybrid Discs and Dual-Drive Systems

In the mid-2000s, some hard drive manufacturers, such as Samsung and Seagate, theorized that if you added a few gigabytes of flash chips to a spinning drive, you would get a so-called “hybrid” drive combining large storage capacity with the performance from an SSD, priced slightly higher than a typical hard drive. 

Flash memory acts as a buffer for frequently used files, so your system has the potential to quickly launch and launch your most important apps, even if you can’t directly install anything in that space. 

Hybrid Drives

In practice, hybrid drives like the Seagate Momentus XT work, but are still more expensive and complex than regular drives. They work best for people like road warriors who need a lot of storage and fast boot times. Since they are a momentary product, hybrid drives do not necessarily replace dedicated hard drives or SSDs.

Dual Drive System

On a dual system, the manufacturer will install a small primary SSD (C 🙂 for the operating system and apps, and add a larger, spinning hard drive (D: or E 🙂 to store. This works well in theory; in practice, manufacturers can suck up little with the SSD. 

Windows itself takes up a lot of space on the primary disk, and some apps cannot be installed on other disks. Some capacities may also be too small. 

For example, you can install Windows on a 16GB SSD, but there won’t be much room for other things.

In our opinion, the practical size for a C: drive is 120 to 128GB, with 256GB or more being the best option. Space concerns are the same as with any multi-unit system: you need physical space within the PC chassis to house two (or more) devices.

Smart Response Technology (SRT)

And finally, an SSD and a hard drive can be combined (like Voltron) on systems with technologies like Intel’s Smart Response Technology (SRT). SRT uses the SSD invisibly to act as a cache for the system to wake up faster and open programs. 

As with a hybrid drive, the SSD is not directly accessible by the end-user. SRT requires real SDDs, like 2.5 ”ones, but those drives can be as small as 8GB or 20GB drives and continue to increase performance; Since the operating system is not installed on an SSD directly, this avoids the space problems of the dual configuration mentioned above. 

On the other hand, your PC will need space for two drives, a requirement that may exclude some smaller laptops and desktops. You will also need the SSD and the motherboard of your system to support the cache technology and to make the situation work. It is an interesting course of things.

What’s the Future of HDD Vs SSD?

We don’t entirely know if SSDs will replace traditional hard drives, especially with shared storage waiting for you. The price of SSDs will drop, but they are still too expensive to replace the terabytes of data that some users have on their PCs and Macs. 

Cloud Storage

Cloud storage isn’t free, either – you’ll keep paying as long as you still want personal storage on the Internet. This one won’t go away until we have wireless internet everywhere, including on planes and in nature. Sure, for that moment maybe there is something better.
