Difference Between SSD and HDD | SSD vs HDD

The basic difference between SSD and HDD is that Solid State Drive stores the data in integrated circuits and a Hard Disk Drive stores data magnetically, through spinning disks. They can also be compared in terms of their speed, adaptability, technical modernity, and user experience. 

A Hard Disk Drive is the commonly used storage disk, which uses a moving read/write head to access data. This is the traditional type of storage unit which is used in Computer devices.

On the other hand, a Solid State Drive is a faster, no-motion, and more efficient secondary storage that stores data using flash memory.

SSD vs HDD – Comparative Analysis

A tabulated comparison between the Hard Disk Drive and Solid State Drive is given below. Refer to the points of difference and analyse which among the two is better and more suitable for use. 

Difference Between SSD and HDD
Full Form: Solid State Drive Full Form: Hard Disk Drive
Movement: It is a solid drive, and no movement occurs while its functioning Movement: It is a moving drive, and the hard disk spins when it is functioning
Speed: It has the faster processing speed Speed: The processing speed is low in comparison to SSD
Latency: It has low latency Latency: It has high latency
Storage – When it comes to capacity, SSDs for computers are available in 120 GB to 4 TB capacities Storage – HDDs can go anywhere from 250 GB to 14 TB
R/W Time: It has a shorter Read/Write time R/W Time: It has a longer Read/Write time
Weight: In terms of weight, SSD is lighter in comparison to HDD. This is because no external mechanics or motor is attached to the drive  Weight: HDD is heavier
Power Consumption: No motion results in less use of electricity or power while using these Power Consumption: Because of the spinning platters, more electricity and power is consumed 
Cost: It is a modern storage drive and is costlier Cost: It is a traditional storage drive and a bit cheaper in comparison to SSD
Size: It is smaller in size Size: It is larger in size
Safety: SSD is more reliable in comparison to HDD Safety: In case of any error in the drive, the entire HDD may crash and result in loss of data. This makes it less reliable

All the points mentioned above, clearly state that although they are both storage devices and are used to boot the system, their features and functioning is different. 

Both Solid State Drive and Hard Disk Drive are Input-Output devices and form an essential part of any computer system. Aspirants can also know the Fundamentals of Computer, at the linked article.
