SSD (Solid state drive): A solid state drive or solid state disk is a solid state storage device that uses integrated circuit. It provides substantial benefits over traditional hard drives.
HDD (Hard disk drive): HDD’s were firstly introduced by IBM in the year 1956. HDD can store data for a long period of time and capable of storing huge amount of data cheaply.
Difference between SSD and HDD: There are many differences between SSD and HDD. Some of them are explained below.
- AS compared to HDD, the prices of SSD are very expensive.
- HDD has large capacity for storing data (for desktop- 6TB) while in SSD you can store maximum 1 TB data in desktop.
- Battery life of SSD is more as compared to HDD.
- There is no noise in SSD because there is no spinning part but due to moving parts and audible clicks HDD can be heard.
- Due to spinning of platters, HDD can be vibrated while there is no any vibration in SSD.
- File copy or write speed in SSD is 200 MB/s and up to 500 MB/s while in HDD, speed of copy of files are 50 MB/s to 120 MB/s.
- File opening speed of SSD is 30% faster than HDD.
- There are chances of erase of data due to magnets while SSD is safe and there is no any chance of data erase in SSD.
- Average time between failure rates of SSD is 2.0 million hours while mean time between failure rates of HDD is 1.5 million hour.
- Heat produced by HDD is higher as compared to SSD because of moving parts.
- Boot time of operating system is around 10-13 sec in SSD while in HDD boot time is approximately 30-40 sec.
SSD’s are good when:
- If you are looking for a faster performance
- If you have no issue of limited storage capacity
HDD’s are good when:
- When you don’t want to spend more money.
- If you have no issue of the system boot time then you can go with HDD (Takes 30 to 40 second).
- Looking for a large storage capacity then go with HDD. HDD can store up to 6 TB data and newly launched HDD can store up to 10 TB data.
