HDD VS SSD Difference Between SSD and HDD
What is a Solid State Drive (SSD)?
Solid
State Drive (SSD) is a non-volatile storage device that stores and
retrieves data constantly on solid-state flash memory. However, this data is
stored on interconnected flash memory chips instead of platters, which makes
them faster than HDDs. It provides better performance compared to HDD.
What is a Hard Disk Drive (HDD)?
An
HDD uses magnetism, which allows you to store data on a rotating platter. It
has a read/write head that floats above the spinning platter for Reading and
Writing of the data. The faster the platter spins, the quicker an HDD can
perform. HDD also consists of an I/O controller and firmware, which tells the
hardware what to do and communicates with the remaining system. The full form
of HDD is Hard Disk Drive
HDD vs SSD power consumption
SSDs are more power-efficient than hard disk drives for a good reason:
They have no moving parts. The average HDD needs between 6 and 15 Watts of power whereas
an SSD needs only between 2 and 5 Watts.
Difference between HDD and SSD
·
SSD is faster at reading and writing
data, whereas HDD has a slower reading and writing data speed.
·
SSD has lower latency, whereas HDD
has higher latency.
·
SSD supports more I/O operations per second
(IOPS), while HDD supports fewer I/O operations per second (IOPS).
·
SSD does not produce such noise, on
the other hand, HDD can produce noise due to mechanical movements.
·
The moving parts of HDDs make them
vulnerable to crashes and damage, but SSD drives can tolerate vibration up to
2000Hz.
·
SSD stands for Solid State Drive,
whereas HDD stands for Hard Disk Drive.
·
HDD
has longer Read and Write time. SSD has a shorter Read and Write time.
·
HDD has higher latency SSD has a
lower latency.
·
HDD supports fewer I/O operations per
second (IOPS). SSD supports more I/O operations per second (IOPS).
·
HDD drive is older and more
traditional. SSD is a newer type of storage drive.
·
HDD can produce noise due to
mechanical movements. SSD does not produce noise.
·
HDD stands for Hard Disk Drive. SSD
stands for Solid State Drive.
SSD Vs HDD Speed
In
terms of speed, SSDs are much faster than HDDs because SSDs does not have
electrical circuitry and moving parts as HDD. A typical 7200 RPM HDD can
deliver read/write speed of 80 to 160 MB/s while a typical SSD can deliver
read/write speed of 200 to 550 MB/s which makes it an ideal choice for better
performance.
The hard disk is made up of a
number of spinning magnetic platters that store data and a number of
reading/write heads on mechanical arms that move on the surface of the platters.
To read or write data at a certain sector of a platter, the head requires to move to the appropriate position and then need to wait for the sector to pass underneath it when the platter rotates.
How SSD works?
SSD drive works completely different than a HDD. It uses a solid
state medium, typically NAND (often known as flash). Data is written to or read
from the NAND by a controller, which is consider the brains of the device.
With SSD, there is no variable seek time or rotational latency
because all the parts of the SSD can be accessed in the same amount of time.
SSD read and write speeds are uneven, so data reads are very fast, but SSD
write speeds are quite slower. That is because SSD
storage is made up of individual NAND cells, which helps you to store
one bit of data, and groups of cells are organized into pages. Moreover, groups
of pages are organized into blocks.
Merits of HDD
- It provides a large storage capacity.
- The stored items are not lost, even if the
computer is shut down.
- It is fixed inside the computer so it can’t be
lost.
- Computers can communicate with them easily.
- It can store data like text documents, images,
videos, etc.
- HDD device can store operating system files
and software related files.
- It sizes very small, and it is portable in
use.
- They are cheaper compared to SSD.
Merits of SSD
- SSD drive offers access speed of 35 to 100
micro-second. So it is able to deliver 100 times the performance of HDDs
- SSDs have lightweight components or moving
parts, as they are more mobile-friendly and are much better suited for
constant traveling.
- SSD drives are resistant and highly durable
- SDD uses flash memory to store data, which
provides better reliability
Demerits of HDD
- If hard disk crashes, the computer will not
work.
- You will lose your important data if the HDD
drive crashes/ damages.
- In the case of hard disk failure, it is
difficult to perform the data recovery.
- Regular “head” can crash, which damages the
surface of the disk.
- The hard disk is fixed inside the computer, so
you can’t transfer to another computer.
Demerits of SSD
- Upfront cost of for SDD is much higher than
HDDs
- SSDs have a limited number of times data can
be written, erased, and rewritten to a portion of the drive.
- The maximum capacity of an SSD is limited.
Though, advancements in flash memory are consistently increasing the
storage capacity of SSDs.
Q 1. SSD vs HDD: What is the difference?
Ans. SSD stands for Solid State Drive with low latency and fast processing speed. On the other hand, HDD stands for Hard Disk Drive with high latency and the processing speed is low in comparison to SSD.
Q 2. Which between SSD and HDD is cost-effective?
Ans. Hard Disk Drive is a traditional storage drive and is costlier in comparison to Solid State Drive, which is a modern storage device.
