You might be hearing the term Solid State drive these days. A lot of people are unaware of the SSD. SDD is much faster and efficient than the HDD. The SDD is the future of the storage computing as it is much more flexible than the hard disk.
The SSD can be considered as a big microchip with no movable parts. On the other hand, the hard disk has a movable hand that goes from sector to sector that reads and writes the data. So, an SSD is faster than the HDD.
HDD V/S SDD
Power draw and the battery life
An SDD takes less power to operate than the HDD. The SSD takes around 2 to 3 watts to operate meanwhile, the HDD takes around 7 to 8 watts to operate. This means that the SSD can operate 30 minutes more than the HDD.
The cost of the SDD is higher than the HDD. An SSD would cost you around $0.20 per gigabyte meanwhile the HDD will cost you around $ 0.04 per gigabyte.
The HDD is available at a higher capacity than the HDD. An SSD would be maximum of 1 TB for the laptops and 4 TB for the desktops. Meanwhile, the HDD can be 2 TB for the laptops and 10 TB for the desktops at the max level.
Operating system boot time
An SSD takes up 5 to 10 seconds to boot up meanwhile, an HDD takes up around 40 to 50 seconds to boot up. SSD is even faster with the Windows 10.
SSD makes no noise while the HDD’s spinning and clicking sound could be heard
There is no vibration in the case of the SSD meanwhile, the HDD makes up the vibrations because of the moving platters.
SSD doesn’t produce any heat as it doesn’t have any moving parts. The HHD too doesn’t produce any heat but some amount of heat is produced due to the spinning of the platters.
The failure rate
The failure rate of the SSD is a mean time of 2 million hours. The mean time failure rate of the HDD is 1.5 million hours.
The writing speed of the SSD is above 200 Mbps. The HDD lacks at this as it ha sthe4 writing speed of just 50 to 120 Mbps.
File opening speed
The file opening speed of the SDD is much faster than the HDD. The SDD opens up the files at a rate of 30 % faster than HDD.
Both HDD and SDD have full disk encryption available in some of the models.
Effects of the magnetism
The SSD is not affected by the magnetism. The HDD can be affected by the magnetism as it can erase its data.
