Is it good to use a mechanical hard disk or a solid state hard disk?

  •      In today's life, all kinds of touch products are common, touch one machine is also the most common one in our life and work schedule. It is composed of advanced touch screen, motherboard, memory, hard disk, video card and other electronic components. It works just like a traditional PC. As an electronic product, storage is a must, and storage is essential to the hard disk. There are two types of hard drives: mechanical hard drives and solid state hard drives.

  •      With the development of technology and the demand for storage by customers, the problem of storage hard disk selection has also appeared on the touch all-in-one. Is that the touch one machine is to choose to install a mechanical hard disk or a solid state hard disk?
  •  
  •      For many consumers, the knowledge of these professions is not available, and there is a bit of a circle in how to choose. KONWAHI touch one machine manufacturer technology Xiaobian to answer the difference between mechanical hard disk and solid state hard disk.

  •   The difference between a mechanical hard disk and a solid state hard disk for a one-touch machine: 
  •  
  •      A solid-state hard disk, referred to as a solid disk, and a solid-state hard disk using a solid-state electronic storage chip array, is composed of a control unit and a storage unit (FLASH chip, DRAM chip). There are no mechanical parts inside the SSD solid state drive, so even in the case of high-speed movement and even tilting and tilting, it will not affect the normal operation, and the possibility of throwing away data in the event of bumps and sensation is minimized.
  •  
  •      Mechanical hard disk is a traditional general hard disk, mainly consists of: disk, head, disk shaft and control motor, head controller, data converter, interface, cache and so on. All the discs in the mechanical hard disk are mounted on a rotating shaft, and each disc is parallel. The mechanical hard disk has a magnetic head on the storage surface of each disc, and the spacing between the magnetic head and the disc is shorter than that of the hair. The diameter of the wire is still small, and all the magnetic heads are connected to one head controller, and the head controller acts as the movement of each head. The head can move along the radius of the disc, and with the high-speed rotation of the disc thousands of revolutions per minute, the head can be positioned to read and write data before the specified orientation of the disc. Hard disk as a fine device, dust is its enemy, it is necessary to completely seal.

  •      Mechanical hard drives are disk-type and data is stored in disk sectors. The solid state hard disk is made of flash granules (memory, MP3, U disk, etc.), so it is lighter in weight. Without mechanical motor and fan, it means that there will be no noise during operation, and it is not afraid of bumping. Shock, vibration. Because the flash media, the seek time is almost 0, the speed of writing continues to be faster than the mechanical hard disk, and it will not be the same as the mechanical hard disk because the inner and outer ring partitions of the disc cause different speeds, and the solid-state hard disk application is new and will be the future.
  •  
  •      The maximum capacity of SSDs is now only 4TB, and the capacity of SSDs at the same price is much smaller than that of mechanical hard drives. This is the biggest advantage of mechanical hard drives for SSDs. In addition, SSD uses flash granules to store data. Even with SLC, it only needs 100,000 read and write lifespans. The relatively low cost of MLC has up to 10,000 read and write lifespans. The number of flash granules erased is only 1000 times. In contrast, the mechanical hard disk can read and write more times, and there is no need to worry because the repeated erasing shortens the life. The storage media is different, and the mechanical hard disk has a longer life.
