  •      The appearance of the intelligent conference touch all-in-one machine is a bit like an LCD TV. It displays various contents through a large size and has a touch function, which can realize touch operation. At the same time, it cooperates with the attached accessories to solve the need for multi-person coordination in the conference. The smart conference touch all-in-one machine mainly faces corporate offices, corporate meetings or discussions, and communication meetings.
  •  
  •      The intelligent conference touch all-in-one machine integrates computers, projectors, conference software, electronic whiteboards, televisions, advertising machines, and stereos. It has the functions of writing at any time, intelligent annotation, simultaneous human-computer interaction, multimedia, and remote video conferences. Integrate multiple technologies such as high-definition display, multi-human-computer interaction, multimedia information processing and network transmission. Widely used in technology, finance, real estate, manufacturing, government affairs, education, media, advertising, conference, transportation, hotel, medical, commercial display fields, etc.

  •      At present, there are two types of hard disk applications in the conference touch all-in-one machine on the market: the choice of mechanical hard disks and solid-state hard disks, which is very blind to consumers. The technical editor of KONWHAI conference touch one machine manufacturer introduces some of the most basic knowledge.

  • Notes on hard disk selection

  •   Analysis of the matters needing attention in the selection of the hard disk of the conference touch one machine:  
  •  
  •      Mechanical hard disk is mainly composed of: disk, head, disk shaft and control motor, head controller, data converter, interface, cache, etc. All the discs in the mechanical hard disk are mounted on the rotating shaft, and each disc is parallel. The mechanical hard disk has a magnetic head on the storage surface of each disk, and the interval between the magnetic head and the disk is shorter than the spacing 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 is used to move each head. The magnetic head can move in the radial direction of the disk, and as the disk rotates at high speed thousands of revolutions per minute, the magnetic head can be positioned to read and write data before the designated direction of the disk. The hard disk is a delicate device, and dust is its enemy. It should be completely sealed.
  •  
  •      The solid-state drive consists of a solid-state electronic storage chip array, including a control unit and a memory unit (FLASH chip, DRAM chip). There are no mechanical parts inside the SSD, so even tilting at high speeds will not affect normal use, and the possibility of discarding data in the case of collisions and sensations is minimized.
  •  
  •      Mechanical hard disks are disk types, and data is stored in disk sectors. Solid-state drives consist of flash memory particles (memory, MP3, USB, etc.), so they are lighter in weight. There are no mechanical motors and fans, which means that there is no noise during operation and you are not afraid of bumps. Due to the use of flash media, the seek time is almost zero, the write speed continues to be faster than the mechanical hard disk, and it is not like the mechanical hard disk, because the internal and external ring partition discs cause different speeds.
  •  
  •      Different storage media, the capacity of mechanical hard drives is getting longer and longer. The maximum capacity of SSDs is only 4TB. The capacity of SSDs at the same price is much smaller than the capacity of mechanical hard drives. This is the biggest advantage of SSD mechanical hard drives. In addition, SSDs use flash memory particles to store data. Even with SLC, it only requires 100,000 read and write lifetimes. The relatively low cost of MLC has up to 10,000 read and write lifetimes. The number of flash particle erasures is only 1,000. In contrast, mechanical hard drives can be read and written more times, and there is no need to worry, because repeated erasure will shorten the service life.
  •  
  •      Therefore, you need to choose whether to use a mechanical hard disk or a solid-state hard disk for the conference touch all-in-one according to your own use. As an input device, KONWHAI conference touch all-in-one machine has many advantages such as ruggedness, fast response, space saving, and easy communication. The touch and query all-in-one machine has a human-computer interaction function, the operation is more personalized, and the information display query is more convenient and fast.
