Key Differences Between SSD and HDD

Posted On May 24, 2021

Today we will discuss on the Key Differences Between SSD and HDD

First, let us have a look on what an SSD is and how it works. SSD is Solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. It is also sometimes called a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks. While looking at the working, the first operation is performed by the host where the data is sent to the SSD controller. The controller decides whether to write the data to the NAND memory. This process is like the RAID where multiple NAND chips are simultaneously written by the controller.

Whereas HDD is an electro-mechanical storage device, which is an abbreviation of Hard Disk Drive. It uses magnetic storage for storing and retrieving the digital data. It is a non-volatile storage device. Working mechanism is quite different in comparison with the SSD. Here a platter (magnetic disk) is rotated at high speed with the help of a motor. The head is positioned over the appropriate location using an arm to read and write the data. During the read operation, the head detects the magnetic value. The head modifies the magnetic value during a write.

Both HDD and SSD are advantageous. Let us postulate the same.

SSD:

· It is very fast.

· Does not produce vibrational noises and heat.

· Shock resistant.

· Consumes low power.

HDD:

· Easily available.

· Works well with the large files too.

· Provides a larger storage at smaller amounts.

While comparing both we can come to certain understandings and they are :

Ø The performance of the SSD is far better than the HDD.

Ø SSD is more durable and failure resistant than HDD as all of its parts are fixed, unlike HDD which contain moving parts and are susceptible to damage.

Ø The power consumed by the HDD is greater than that consumed by SSD, its reason is that the HDD uses energy eating motors for its functioning.

Ø The access time of the SSD is excellent for smaller files and data transfer rate can be between 100 MB/s to 600 MB/s. Conversely, HDD access time is 10 times slower than the SSD. It provides a data transfer rate around 140 MB/s, however, large files do not degrade its performance.

Ø Seek time and rotational latency of the SSD is superior to HDD and it also takes less time in a startup.

Ø The SSD is costly than HDD and it provides less storage capacity compared to HDD in the same amount.
