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.

In this article, we shall discuss the various points of comparison between SSD and HDD for aspirants preparing for the upcoming IAS Exam.
Similar computer-related topics may be asked in the UPSC and other Government exams conducted in the country. Either a separate Computer Knowledge section may be included or questions may be asked in general awareness. Specifically, for IAS, such questions are included in the Science and Technology part of the syllabus.

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 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|
