Most people now buy laptops for their computing requirements and the most difficult decision for them is to choose between SSD and HDD. Which one is the best, SSD or HDD?
There is no direct answer to this question; Each buyer has different requirements and you will have to choose the correct option considering your requirement and budget.
If you need fast boot-up and fast memory and you do not have any problem with the budget then you should definitely choose SSD, though HDD is better in your place, you just need to identify your requirement.

What is SSD?

SSD
We do not make any assumption here and keep this article at the level that someone can understand. You are shopping for a computer and just wondering what SSD really is? To get started, SSD is called Solid State Drive.
You may be familiar with USB memory stick- SSD can be considered as a larger and more sophisticated version of a polite USB memory stick, like a memory stick, there are no running parts in SSD. Instead, information is stored in microchips. On the contrary, a hard disk drive uses a mechanical arm which moves around and reads information from the correct location on the storage plate.
SSD works on flash memory. This is a non-volatile type of memory. What does non-volatile mean? The simple answer is that you can close the disc and it will not "forget" what was stored in it. This is certainly an essential feature of any type of permanent memory.
To read and write SSD, there is no mechanical hand, but it is based on an embedded processor (or "brain"), which is called Controller. The controller is a very important factor in determining the speed of SSD. It decides how to store, retrieve, cache and clean data, can determine the overall speed of the drive.
The SSD form factor is actually similar to a regular hard drive, it comes in a standard 1.8 ", 2.5" or 3.5 "size, which can fit in the housing and connectors for the same size of the hard drive. The connector SATA used for these standard sizes is small SSDs that are called Mini-SATA (MSATA) and are fit in the mini-PCI Express slot of the laptop.

Advantages of SSD:

  • SPEED- Its first advantage is speed. It accesses the data or information very fast. 
  • RESISTANT: SSD's are strong. 
  • Low power consumption: It consumes very less power as compared to HDD.
  • Long Lifespan: Its lifespan is too long because it does not contain any moving part inside it. It is flash-based just like RAM.

Disadvantages of SSD:

  • High Cost: SSD's are a bit costlier than HDD. 
  • Fragment issues.
  • Less amount of storage available.

What is HDD?

HDD
In techno-language, hard disk drives or HDD techniques are around for years. HDD was first introduced by IBM in 1956 - Yes, this is a 60-year-old technique.
It uses an HDD Magnetism to store data on the rotating plate. The read/write head floats above the spinning plate and writes data. Specific laptop drive spins 5400 RPM (Rotation per minute) or 7200 RPM today, although some server-based plates spin up to 15,000 RPMs!
The key advantage of an HDD is that it is capable of collecting a lot of data these days, 1 terabyte (1,024 Gigabyte) storage is not uncommon for a laptop hard drive, and density continues to grow. However, the cost per gigabyte is now hard to calculate, though it is safe to say that all HDDs are much cheaper than SSD. Compared to a comparison, popular WD Black (1 TB) goes for almost $ 69 on most websites, while the OCZ Trion 100 (960 GB) and Samsung 850 EVO (1 TB) SSDs go for $ 199 and $ 319, respectively, three to five times the price of WD So if you want a big and cheap storage, using a hard-disk drive is definitely a more attractive way to go.

Advantages of HDD:

  • Easily available: It is easily available in the market or on some websites.
  • Cheap: It is very cheap as compared to SSD's.
  • Large Capacity of storage.
  • Works well with bigger files.

Disadvantages of HDD:

  • Short Lifespan: Normally, the lifespan of any HDD are about 5-6 years.
  • Less Speed: Speed is slow because of its a mechanical type of device.
  • Power Consuming: HDD consumes more power because of its mechanical.
  • Chances of damage are more in HDD because it contains moving part inside it.
  • It makes noise while working
  • It occupies a lot of space.


Comparison Table between SSD and HDD:


Basis for comparisonSSDHDD
PerformanceIts performance is very good.Compared to SSD, it performs less or average.
StrengthThere is strongness in it.It is less robust.
CostCostlyInexpensive
Access timeSmaller than 100 microseconds.2.9 - 12 microseconds
Power ConsumptionLessMore
Data Transfer RateProvides good speed for data transfer.speed is less than SSD.
Starting TimeSome milliseconds are needed to get started.It takes a few seconds more than the SSD to start.

Can you have SSD and HDD both in single computer ( Hybrid Drives):

Yes, you can have ssd and hdd both in a single pc. If you have only a hdd, there is space given or available to install another drive, you can add a ssd at that place. Your pc will not be that portable after that but it will be fast.
Or you can also use Hybrid drives. Hybrid drives contains both, HDD and SSD. Hybrid drives come in different storage capacities. In Hybrid drives, the SSD porition is used for for storing program files and running OS whereas the HDD part is used for storing you big files. But PC's with Hybrid drives always lags in performance as compared to individual SSD drives. So, take help of experts before installing  Hybrid drives in your PC.

Conclusion:
SSD (solid-state disk) is a good storage medium when the user wants a more reliable, efficient solution while HDD (hard disk drive) is a better option when effective storage is required.
