The hard drive is an important component in the computer, all of the user's data such as the Windows operating system or personal data is stored in the hard drive and they are always accessed regularly.
Hard drives are related to important issues when using the computer such as the speed at which the computer is started up, the speed at which it is copied and exported, and the safety of personal data stored on the computer. So when buying a laptop the specifications of the hard drive are also worth paying attention to.


 

Current hard drives have two main types: HDD (Hard Disk Drive) and SSD (Solid State Drive).

HDD (Hard Disk Drive) - An HDD is basically a metal disk coated with a magnetic layer, which is the place to store your data. When the HDD is working, a read / write head on a metal rod accesses the data while the hard disk hardware is rotated in a disk holder.

 


 


SSD (Solid State Drive) is a type of solid-state drive, researched and manufactured by hardware experts to compete with traditional HDDs, improving speed, temperature, and safety. data and power consumption. In other words, SSD is a later development technology, so it is somewhat superior to HDD, but at present, because the price is still too high, laptop computers still mainly use HDD.


 

Benefits of SSD:

  • Faster operating system boot times.
  • Copying / exporting data to other devices is faster.
  • Run the software on the machine faster.
  • Excellent data protection due to high shock resistance and it is made of good components so it is more durable.
  • Less noise, more effective heat dissipation.
  • Bandwidth for reading / writing large data increases the working capacity of the computer. 

 


 

In addition, there are hybrid hard drives

Hybrid HD is also known as hybrid hard drive. It is the product of a combination of high capacity HDD and high speed SSD hard drive. Hybrid HDD works according to the principle, when the user uses the system to check which applications or data are used regularly will be saved to the SSD, while other applications and data are saved to the HDD. In short, the HDD to store data and the SSD to store the data are often used to help the CPU access faster.


 

SSHD (Solid State Hybrid Drive) or solid state hybrid drive. It is a type of hard drive that is combined between the platters of the HDD for storage and the NAND Flash chips like the SSD used to retrieve data. SSDH differs from Hybrid HDD in that the capacity of NAND flash chips is usually only 4 or 8 GB, while Hybrid HDD can have higher SSD capacity (16GB or 32 GB).
