What's the Difference between HDD and SSD?

We used to hear that Windows 10 users want to transfer Windows 10 OS from HDD to SSD. What is HDD and SSD? What’s the difference between them? Why people want to migrate operating system to SSD? There are many questions about this action.

HDD, the abbreviation of Hard Disk Drive, is the most basic storage disk of computer. It is a metal platter with the magnetic coating. When it spinning, the data can be read and written. More specifically, the local disk on the computer has many drives we marked as C, D, F, and we usually called those drives hard disk drives.

SSD, the short of Solid State Drive, is also a storage disk which made by solid state electronic storage chip. Unlike HDD, SSD has no moving parts, the data are stored on the memory chips(consists of flash chip and Dynamic Random Access Memory(DRAM) chip). So, there is no platter spinning while the data read or written on SSD.

The Advantages of Transferring Windows 10 from HDD to SSD

As we mentioned above, SSD stores by memory chip rather than a metal platter. It does have many advantages:

  • The data on the SSD can be read and written faster because the store way is different with the traditional HDD.

  • The data on SSD is safer than HDD.

  • There is no noise of metal platter spinning.

  • The SSD can work under more serious environment compared with HDD (the SSD can work normal between -10 to 70℃ while HDD can work between 5 to 50℃).

After you move Windows 10 to SSD, the computer’s performance will be improved greatly. It will run faster than before. But, how to transfer Windows 10 from HDD to SSD without reinstalling?
