Hard drives are classified as solid-state drives (SSDs) and mechanical hard drives (HDDs); SSDs use flash memory particles for storage and HDDs use magnetic disks for storage.
Introduction to mechanical hard disk:
A non-volatile (non-volatile) storage device that uses hard, spinning platters as a base. It stores and retrieves digital data on a flat magnetic surface. The information is written to the disk by an electromagnetic stream through a write head that is close to the magnetic surface and by an electromagnetic stream to change the polarity. Due to its small size, large capacity, speed, and ease of use, it has become a standard feature of PCs. It uses aluminum alloy and other metals as the disk base, the disk surface is covered with a magnetic recording layer, the magnetic layer can be taken and thrown coatings made by the industry, at this time the magnetic powder is discontinuous particles exist; can also be and electroplating, chemical plating and sputtering and other methods of continuous film disk
Solid State Hard Disk:
Solid State Disk (SSD) Solid State Disk (IDE FLASH DISK, Serial ATA Flash Disk) is the most important and most important of all, it is the most important of all, Serial ATA Flash Disk) is composed of a control unit and a storage unit (FLASH chip), simply put, it is an array of solid-state electronic memory chips and made of hard disk (the current maximum capacity of 1.6TB), solid-state hard disk interface specifications and definitions, functions and methods of use with the ordinary hard disk is exactly the same. The shape and size of the product is also completely consistent with the ordinary hard disk, including 3.5", 2.5", 1.8" types. Because the solid state hard disk does not have the rotating medium of ordinary hard disk, thus excellent shock resistance, while the working temperature is very wide, extended temperature electronic hard disk can work in -45 ℃ ~ +85 ℃. Widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, etc., navigation equipment and other fields.
Note: Now there is also a network hard disk called: "network U disk", is the user's files stored on the Internet, the user is convenient to "carry" their files, easy to share with his friends and family "share" their files, all the operations in the website page to complete. All operations are done on the pages of the site. There are no restrictions on file types.
