SSD Vs HDD : Which One Is Better and The Differences Between Solid State and Hard Drive

When we buy computers, we hardly have the choice to select storage media.  What we can do is, that we can buy portable device know as SSD or Solid state drive. Along with SSD, our systems have already HDD or Hard disk drive. So now we have the option to configure our system for both of them.


Still, before setting up your system, you should know your requirements, budget, the capacity of system and compatibility. SSD and HDD both are completely different yet similar things. You should choose them by your need. We will discuss both of them along with the difference between them in this article. First of all, Let’s know basics about both of them.

Hard Disk Drive or HDD:

The hard disk drive is a conventional storage system present in all the computer systems. The data continues to stay even after you turn off the system. The disk drive is an element plate that has a magnetic sheet over it. It can be used for storing data. It is still in use because of it is cheaper than SDD. The disk size of HDD is typically 500 GB, 1TB, 2TB, 4TB, 8 TB, etc., and the sizes in which it comes are 3.5, 2.5, and 1.8 inches, etc. The interfaces of HDD are PATA, SATA, or SCSI. HDD with PATA and SATA used in home computers and it is cheaper than others.

Solid State Drive or SSD:

An SSD is functionally similar to HDD, but data is rather saved on interconnected flash memory chips that preserve the data even when there is no power. The chips may be installed on the motherboard (as on Palmtops and ultraportables devices), on a PCI Express card (high-end workstations). These memory chips are of a separate model than is used in USB thumb disks and are typically durable and more stable. SSDs are costly than USB thumb drives of the same functions.

Difference Between Solid State and Hard Disk:

1. Speed comparison:

As we Know Hard disks are old systems. So definitely it would be slower than SSDs. HDD take more time to boot than SSD. Also, laptops with SSD in it loads applications faster than laptops with HDD. So if you are a professional, and always need to wind your work up in time, Go for SSD.

2. Price Comparison:

Being a better option, SSD is expensive as compared to HDD. 2 TB of any right solid state drive will cost at least Rs. 3-4k more than same capacity Hard disk. HDD is available at the economical price, so if your budget is small, go for HDD instead of SSD. There is no chance shortly for SSD price to come down (unless we discover another alternate).

3. Durability Comparison SSD vs HDD:

Hard disks being metallic plates with a magnetic coating, prone to damage. If someday you broke your laptop, or sudden power failure happens, You may lose your data. On the other hand, SSD, having no moving parts, no matter what, Your data will be safe. So if you use your laptop/computer roughly, I advise you to go for SSD for data safety.

4. Fragmentation Error Comparison:

HDD has rotatory disk surface, and it works well with the large sized file that is laid down in adjoining lots. When HDD start to load up, big files can spread around the moving disk, causing the drive to undergo fragmentation. While you can treat this error using third party software, hard disk drives can still grow fragments.

Whereas solid state drive has no such issue as HDD. It does not get fragmented because it has no physical head for storage. It can store data anywhere. That is why SSD is comparatively faster than HDD. So if you prefer costlier but error free, fast device, choose SSD.

5. HDD is Noisy:

It’s a fact that mechanical parts (Magnetic rotating plates in HDD) will make more noise than non-mechanical (solid state drive) one. HDD will make noise when its parts move to process data while the solid state drive gives the user a sound free environment. It’s not a big difference, but still, someone may prefer noise free system.

6. Heating Issue:

It is evident from the fact that HDD has moving parts, so it generates more heat than solid state drive. SSD uses flash memory, produce lesser heat and hence its life span is more than HDD.

7. Availability in Market:

While the HDD is an integral part of old systems and solid state drive is the choice for new age laptops, both of them going to stay in the market together. There is no chance of one to vanish anytime soon.

8. Size comparison of Physical Drive:

SSD is comparatively smaller and compact than HDD. So it is easy and convenient for the user to carry it with him as compared to large hard disks.
