Differences between SSD & HDD - Many peoples want to know what is the differences between SSD & HDD. When you go to buy computer, peoples get confused whether to choose SSD or HDD as a secondary storage device. Understand what is the difference between SSD and HDD and what is the difference between the speed of both - Hdd & SSD
Hard Disk Drive vs Solid State Drive:
When you think of getting a new computer system, offline or online, you get two options for storage drive, first SSD which is Full Form Solid State Drive and second option HDD which has Full Form Hard Disk Drive, if seen technically. But SSD and HDD work in the same way but their features differ from each other, due to lack of information, we are not able to decide quickly what to take between SSD and HDD for our computer.
For this, firsts of all, we have to understands what is the differences between theses two and what are the specialtie, then let's us first knows what is HDD or Hard Disk Drive.
What is HDD or Hard Disk Drive?
The world first Hard Disk Drive was invents in 1956 by IBM Company. Magnetisms technology was used in this Hard Disk Drives, it's is also called Fixed Disk, magnetic disk was used in our Hard Disk Drive to store datas. Used to goes, this disk was coated with magnetics material on both side, read and write head on each surfaces of the disk which can slide back and forth, it is called Spinning Platter Rotation Platter is rotated rapidly to store data in hard disk. It Rotations Speed range from 3600 revolution per minutes (Rotation Per Minutes) to 7200 revolution per minute (Rotations Per Minutes) or RPM.Currently somes hard disk drive spins up to 15000 RPM, the fasters the hard disks spin, the faster it will be ables to reads & write datas, Hard Disk Drive is very reliables medium to store informations, but it is very sensitive There is also a particle of dust, if it goes inside the hard disk, it can spoil it,Therefore it is permanently sealed in a metal box, but its biggest advantage is that it is easily available to the common user at a very low cost and a lot of data can be stored in it. In today's time hard disk drives from 1TB to 10TB are available in the market, which starts from around Rs 3000.
What is SSD or Solid State Drive?
SSD's Full Form is Solid State Drive, you can call it a bigger form of Pendrive, a little more data can be stored in SSD than Pendrive, similar to Pendrive, there is a card in SSD, there is no magnetic disk in it. There are many micro chips in this card in which data is stored, that is why Solid State Drive is faster than Hard Disk Drive, SSD is a Non Volatile Memory. Even after it is not destroyed, SSD has a Not End (NAND) Flash Memory, it is used in many types of storage drives such as USB Data Card, Smart Media Card, SD Card, Mini SD Card, etc., All of them There is no memory loss of any kind
How does SSD work:
SSD has a controller to read and write data, which is also called the brain or processor of SSD, this processor stores the data and also cleans up the memory of the SSD.
Type Of SSD:
SSD looks like a big mobile battery, its SSD card is placed inside a plastic or metal card, there are many types of SSD according to the size, the standard size SSD are as follows -
1.8 Inch
2.5 Inch
3.5 Inch
This SSD easily fits in your CPU Case, apart from this the SSDs used for Leptop are called Mini SATA (mSATA) according to the connectivity and speed, the SSDs are of this type.
