SSHD vs. SSD vs. HDD

sshd vs ssd vs hdd

This post will contrast the three most common computer storage options, namely SSD, HDD, and SSHD, side by side. By the conclusion of this article, you’ll know which one best meets your needs and fits your budget. Let’s get started without further ado.

Hard Disk Drive – HDD

The HDD has been around for a long time. IBM was the first to deploy it in 1956. It features a mechanical arm that moves to read and write data to a specific spot.

If the user requires any info, HDD must go around that location and retrieve the data, which increases the time it takes to retrieve any necessary information using HDD. To summarise, recovering data from an HDD necessitates physical movement.

Since HDDs have the ability to write data to any spot on the plate at any moment, there is a risk of data overwriting, which might cause problems for particular events. The HDD has a distinct benefit in that it can store a large quantity of data.

Pros of HDD

  • The most cost-effective storage drive.
  • More storage space is available.
  • In the read/write cycle, it has a long lifetime.
  • Data recovery is significantly more manageable since it works across magnetization and demagnetization.

Cons of HDD

  • Moving parts are less trustworthy, putting HDDs at risk of being damaged in the event of an accident.
  • The speed of reading and writing is slower.
  • It makes a lot of noise.
  • Bulky and large.
  • It is inefficient in terms of energy and generates noise.

How does it work?

One platter is used in a hard disc drive, and both sides of the platter are magnetized. The platter is one of its components. There are millions of tiny little regions on this plate. This platter’s magnetizing and demagnetizing zones act in tandem.

To read and write data, a read or write head travels above the platter. There are two reads or write heads on each plate. One is for upper surface reading, while the other is for bottom surface reading.

To begin, the HDD retains a map of sectors, indicating which sectors have data and which are empty. The new data is then written over the free sectors when it has found them. If the data must be read from the HDD, the same procedure will be followed but in reverse.

Solid State Hybrid Drive – SSHD

A hybrid of the two worlds, with a quick SSD cache and greater HDD storage.

SSHD is the abbreviation for Solid State Hybrid Drive. SSHD is a hybrid of SSD and HDD storage. You may use SSHD as the optimum storage and performance option while staying within your budget. SSHD gives you the storage capacity of a hard drive with the performance of a solid-state drive.

It has a combination of compact and fast NAND flash memory. For lightning-fast performance, the SSHD takes advantage of SSD. It incorporates the HDD’s great capacity and stability. In addition, in SSHD, the Adaptive Memory technology is added.

Pros of SSHD

  • It has a strong speed-to-storage capacity ratio.
  • There are fewer moving parts than on a hard disc drive.
  • It contains NAND flash storage, which allows for quicker access to frequently used data through caching.
  • More read and write cycles than a solid-state drive (SSD).

Cons of SSHD

  • The HDD portion is prone to dropping or exposure, causing the entire SSHD to malfunction.

How does it work?

A small quantity of high-performance NAND flash memory is used by SSHD. This flash memory is used to store the most frequently utilized data. Files can be accessed fast with SSHD since it features an SSD section of the disc that is 8 GB in size.

It includes a memory manager built into the hard drive that will recognize which data and files are accessed the most frequently and store them in the flash memory, which is the solid-state component of the drive. As a result, accessing such files is a breeze since your system remembers all of your regularly used data and files.

Solid State Drive – SSD

SSD is the abbreviation for a solid-state drive. SSD vs. HDD has been compared a lot. It’s similar to USB memory sticks, except that you can use larger SSDs and more complex USB memory sticks.

SSDs can’t be moved because they don’t have any moving parts. Microchips hold the memory in SSDs.

If you want any data, SSD does not need to wander about looking for it; it can obtain it immediately from within. It’s a lot faster than using a hard drive because hard drives have to travel around to retrieve the information they need.

SSDs are available in three standard sizes: 1.8 inches, 2.5 inches, and 3.5 inches.

Pros of SSD

  • Fast read and write rates are available.
  • Since there are no moving parts, it is more dependable.
  • The best power efficiency and the least amount of noise. Good for gaming.
  • It’s small and light.

Cons of SSD

  • It is more expensive than HDD and SSHD.
  • The read and write speed cycles are shorter, and the lifetime is relatively small as well.
  • It has a small amount of memory.

How does it work?

A controller functions as a processor in SSDs and performs all reading and writing actions. SSDs employ flash memory like RAM. However, the memory is not cleared when the power is turned off; it stays in the SSD.

To receive and deliver data fast, SSDs employ a grid of electrical cells. Pages are used to separate these grids. Pages are the storage locations for data. A block is made up of several pages.

SSDs only write if there is a blank page available; otherwise, they do not write on previously written pages. As a result, there is no risk of data overwriting in SSD.

HDD vs. SSD vs. SSHD – Which is better?

When it comes to upgrading laptop storage, deciding between HDD, SSD, and SSHD technologies might be difficult.

Perhaps the most important thing to consider is: how can you have a maximum capacity that is almost as quick as solid-state while remaining within your budget?

Solid-state hybrid drives, in general, can give the most refined mix of performance features and cost considerations to satisfy your requirements.

There can’t be a magic fix that will work for everyone. It is due to the fact that each person has unique requirements. Budget, performance, use case, and other factors might influence people’s responses.

You can go through the pros, cons, performance, and other features of each storage drive and choose the one that best meets your needs. The most critical issue is your budget, and if you’re short on cash, you should hunt for the finest offer possible.


To summarise the SSHD vs. HDD comparison, if you want both storage space and speed, you should choose an SSHD. It’s perfect for a laptop, and mainly if you use it to start Windows, it’s a game-changer.

If you’re on a budget and need extra storage space, an HDD is the way to go.

If you only want storage space, a combination of SSD and HDD can be used as a secondary drive. The SSD stores system data and apps, while the HDD stores backups such as images, media files, and other things.

SSHD is the most recent technology, so if you want to try new things and see what’s new, go with SSHD.
