Beginners Guide to Difference Between SSD and HDD

Today we are going to discuss the difference between SSD and HDD that's Solid State Drive versus Hard Disk Drive. And find out whether it is value for money to go for SSD laptop when you purchase a laptop.

when you want to purchase a laptop, what we usually look for what is the processor we need? and how much ram we need? and what is the screen size of the laptop? and how much graphics memory you need and also how much storage capacity you need? but we usually don't think what type of storage capacity you want and which is better SSD or HDD. Firstly we see how they work.

How Hard Disk Drive(HDD) Works:

The basic working principle here is, As the name suggests its main component is a Disk drive. This hard disk is made up of ferromagnetic material by which your hard disk drive can be magnetically charged. This hard disk has millions or even billions of magnetic regions which can be charged emphatically or even contrarily. Furthermore, here the emphatically charged region represents One (1)and while the adversely charged region represents a zero(0)when you store something like a picture in your computer. The disk starts rotating and the arm will compose the charge of each magnetic region shaping a binary code and will save the binary code.


How Solid-State Drive(SSD) Works:

SSDs are smaller in size is just like your pen drive or flash disk. This dose not have any moving parts, instead there is a controller which helps to access the data from SSD drive. They have a huge number of transistors in them and every transistor is not the equivalent. A few transistors can direct power while different transistors can not lead power. The directing transistor speaks to one, While the non-leading transistor speaks to a zero. The memory controller module in the SSD drive reads that binary information and sends to the computer. This process makes SSDs work so much faster than HDDs i.e. by not using a mechanical arm. So SSDs work a lot faster than HDDs and that's why for gaming purposes SSD hard disk is more reliable than HDD hard disk.


So there are so many advantage of SSD over HDD. But we discussed major SSD and HDD difference:
  • SSDs are smaller in size if we compare with HDDs.
  • When we check SSd vs HDD speed test than SSDs are 5 to 10 times faster than traditional HDDs.
  • SSDs do not have the fragmentation problem that is there on HDDs.
  • SSDs also produce very less heat comparing to a HDDs.
  • If we talk about SSD vs HDD power consumption than SSDs consume less power consumption than the HDD. On average, Samsung SSD drive consumes 60 percent less energy comparing to a HDD.
When we see SSD vs HDD boot time in systems using SSD, the boot time, start time, restart time and application loading time and file access time etc. will show a significant improvement. The performance improvement using an SSD drive is quite significant you will feel like you are using a next level of processor it self. For example, if you use i5 with 256gb SSD it will be faster than an i7 with traditional 1tb HDD. So a 256gb SSD better than a 1tb hard drive(256gb SSD vs 1tb HDD). I am not talking about the SSD benchmark scores here, it may be different. But in day to day usage you will feel like it is faster than an i7.

Few people are still in confusion that do games run better on SSD. So when you start a large game or open an application like Photoshop etc. There are several small files which need to be loaded in to RAM. This means the processor is accessing the storage randomly. In this scenario the performance difference is quite significant when it is compared to SSD and HDD. In an another case, when a large file is copying from one location to other in your computer like you copy a video file of 2GB, the storage is getting accessed serially in that case there will not a huge difference in performance but still it will be faster in case of SSD laptop.

A lot of people are worried about the HDD vs SSD lifespan but the latest SSDs have better life span than HDDs. Also manufacturers said that If you use a SSD like the same way you use a HDD chances are SSD will last longer. Even in the context of damage resistance. SSDs more reliable than hard drive because it has no moving parts like HDDs have. The chance to improve HDD performance is very limited compared to that of SSD and also change of working parts failure is more in HDD hard disk. 

Here one more question occurs that can you use SSD and HDD together. There are hybrid SSDs additionally accessible in the market where you can get 1TB of HDD clubbed with 8GB of SSD. This one is to a greater extent a contrivance than what a genuine SSD can do. Still it will be a little bit faster than HDD even though all the things point out that SSD is the future. 

But the main disadvantage with SSDs and the advantage with HDDs is their STORAGE capacities because as of now SSDs are available in low storage capacities also compared to HDDs. one more problem comes when you look at the price in commercially available SSD and HDD. Because the money you spend to buy a 128GB SSD may give you a 2TB spaced HDD. And that's a very big difference. The cost of SSD is 3 times compared to the normal hard disk drive. This difference turns our eyes to hard disk. But SSDs are much faster. So try to understand your need and decide whether it suits you or not.

For a regular user in my personal opinion i would recommend to buy SSD. There are different ways you can upgrade your existing storage from HDD to SSD. If you do this , your computer will perform way faster than what it is right now.
