1. HARD DISK DRIVE (HDD)
Hard Disk Drive is 50 years old
Technology. There is not so much change in this technology from past 50 years.
It is Old and Reliable Technology. But guys Hard Disk Drive has moving parts.
And that’s why it is Prone to Accident, there are higher chances to broke
parts. But what are that moving Parts? There is a circular disk in it
and its Name is Platter. Your data stored on platter and from there your data
reads or write. How Does it Read Write? Do you know about Gramophone?
Yes, that music player on which a disk moves in circular direction and a point
touch on it and then music plays.
Same it works on Platter. There is a
needle on the platter which read and write when Platter Moves. The faster
Platter moves as much faster your data will be read and write. And that is why
HDDs has RPM (Rounds Per Minute). When you store data in HDD your Hard Disk
will make noise. HDD is bigger in size as compare to SSD. This is cheap in
price and you will get more storage in lower cost. e.g. if you spent 10000 on a
SSD you will get 1 TB Storage, but at the Same time if you spent 10000 on HDD
you will get 6-7 TB Storage. This is old but cheap technology.
NOW LET’S TALK ABOUT SSD

2. SOLID STATE DRIVE (SSD)
There is no moving parts. Do you know that
old computers have memory stick, this is same like that stick. Basically SSD
has memory chips in it. The chips means the more storage. And the best thing is
there is no moving, if it will fall there will be no crack on it, it helps to
increase it’s lifetime. Also it will helpful when you are transferring data, no
moving parts means no noise. And it is much more Faster than HDD. Means when
you look at read and write speed, sometimes it is 5x or 10x faster than Hard
Disk. But it very costly as compare to HDD. Means If a 2TB Hard Disk’s price is
5000 rupees then 2TB’s SSD’s price will
be nearly 8000 rupees.
This is about HDD And SSD. But when we
transfer DATA from HDD there is only one interface called SATA 1 or SATA 2 But
different technologies has arrived in SSD like M.2, NVME which Latest and
blazing fast. This is why interface is also important to decide read and write
speed and SSD has benefit there.

So basically why you need to buy SSD or HDD.
When your first priority is huge storage and tight in budget then you must go
for Hard Disk. If you are building a PC then you must buy a HDD and a SSD. For
more storage you buy HDD and to run applications and windows you should buy a
SSD around 256GB or 512GB. It helps to fast your windows, and to open close
your applications faster and also helps you to store something which you needs
to Run Faster. This the ideal combination in my views. It saves your money. If
you are gamer, video editor or graphics designer then you must go for SSD only.
