THE FUTURE OF FILE STORAGE IS ALREADY HERE! SSDs-Oversimplified!

From quite some time, you have been hearing about SSDs. They say it has more speed and are less noisy. But what are SSDs anyway?
Lets find out. Shall we?

WHAT IS EXACTLY AN SSD?

SSD stands for Solid State Drive. It is an alternative to the the HDD (Hard Disk Drives) that we have been using conventionally in our PCs and Laptops.

They have been a bit popular since quite some time but conversely there Technology is here since the late 80s.

WHAT IS THE DIFFERENCE BETWEEN AN SSD AND HDD?

Since this blog is based on oversimplification, let's just say that an HDD is an Analog watch and an SSD is a digital watch.

Not enough for you Tech urge?

Here we go then.

An SSD is made up of NAND/NOR Flash (Semiconductor Chips). These chips store data in them. 

While, an HDD has a Magnetic plate which rotates and an Arm (Actuator arm) which writes or reads data from.
The data is stored in HDD by magnetising it.

So an SSD is an HDD on steroids.

BUT WHAT MAKES AN SSD  SO FASTER?

As written in the above paragraph, an SSD has data stored in Semiconductor Chips while in HDD, mechanical plate (made of aluminium) is used which is red and written by a rotating arm.

So an HDD is limited by it's Mechanical Limits (the speed at which the arm works) while an SSD is  completely chip-based and is faster.

OK FOR ALL THAT, BUT WHY IS IT SO EXPENSIVE?

While searching online for laptops or computers, you might have stumbled upon some SSDs that are the price of a whole laptop!

The reason behind this is that an HDD is just mechanical mess that is easy to mass assemble while an SSD uses the NAND flash (Semiconductors) that are hard to mass produce and needs more attention while making. 

Also for their amazingly fast read and write rates, the hefty price tag doesn't stick so much after all.

It might seem very expensive to use an SSD everyday, but trust me you have been using it from a long time.

That is your portable SSD which is your FlashDrive (Pen-drive).
Yes Pen-drive too is an SSD though a relatively smaller and cheaper one. 

It too works on the Semiconductor chips (ever wondered why they are so small while hard drives of almost same storage is so big?).
