1. SSD Vs HDD: What is the Difference
between SSD and HDD?

What is the difference between solid-state drives (SSDs) and
hard disk drives (HDDs)? The solid-state drives and hard disk
drives look is similar, but the way they store data is very
different. Each type of drive has pros and cons; how you use
your computer will determine which type is best for you.
Computer repair in Noida is also the best source of information
regarding understanding their differences. This guide to HDD
vs. SSD shows you how each type of storage drive works and
what that means for you.

2. Magnetism is used in an HDD, which lets
you store data on a spinning platter. Its
head can read and write data that floats
above the spinning platter. The faster an
HDD can work, the faster the platter
spins. The HDD also has an I/O controller
and firmware. The firmware tells the
hardware what to do and talks to the
rest of the system.
What is HDD?

3. • Hard disk drives have one or
more magnetically sensitive
platters, an actuator arm with a
read/write head for each platter,
and a motor to spin the platters
and move the arms.
• An I/O controller and firmware
communicate with the rest of the
system and tell the hardware
what to do.
• A solid-state drive (SSD) is a storage
device that keeps data on solid-state
flash memory and does not lose it
when the power goes out.
• However, the data is stored on
flash memory chips linked
together instead of platters.
• Compared to HDD, its
performance is better.
What is an SSD? How does an HDD
work?
• Each platter is made up of
tracks, which are concentric
circles.

4. How does SSD Work?
SSDs are like big USB drives because they use the
same technology.
NAND is a type of flash memory that is used in
solid-state drives.
At the most basic level, data is stored in floating
gate transistors by recording a charge.
The gates are set up in a grid, which is then put
together to make a block.
The size of the blocks can vary, but each row in the
grid is called a page.

5. • HDD reads and writes data more slowly than
SSD. SSD reads and writes data more quickly.
• The latency of an HDD is higher than that of an
SSD.
• HDD can handle fewer I/O operations per
second (IOPS), while SSD can handle more
(IOPS).
• HDD can make noise because it has moving
parts. SSD, on the other hand, does not make
noise.
• HDDs are more likely to crash and break
because they have moving parts, but SSDs can
handle vibrations up to 2000Hz.
Difference between HDD and SSD
SSD
HDD

6. • Sufficient storage space
• The stored items are still there if the computer is turned
off.
• It is built into the computer, so you cannot lose it.
• They are easy for computers to communicate to.
• Stores documents of different types
• The operating system and software files can be stored
on an HDD device.
• Portable
• They are less expensive than SSD.
Advantages of HDD

7. • The access speed of an SSD drive is between 35 and 100 microseconds. So it can deliver 100 times
as much performance as HDDs.
• SSDs have lighter parts or moving parts because they are more mobile and better suited for people
who are always on the go.
• SSD drives are tough and last a long time.
• SDD stores data in flash memory, which makes it more reliable.
Advantages of SSD

8. • If the computer's hard disk fails, it will not work.
• You will lose your important files if the HDD drive crashes or breaks
• When a hard drive stops working, it is hard to get the data back.
• The regular head can crash, which damages the disk's surface.
• Since the hard drive is built into the computer, you cannot move it to
another one.
