is a mechanical hard drive or an SSD? Let’s see together what kind of hard drive it is.

HDDs are mechanical hard disk drives.

HDD is a traditional ordinary hard disk ssd sata 1TB, mainly composed of diskSSD SATA 1TB, head, spindle and control motor, head controller, data converter, interface, cache, etc.

The head can move along the radius of the disk, and as the disk rotates at high speed and several thousand revolutions per minute, the head can be positioned at a designated location on the disk for data reading and writing operations. Information is written to disk by electromagnetic current through a head very close to the magnetic surface, and the polarity changes due to electromagnetic current. Information can be read in the opposite way. A hard drive is a delicate device, and dust is its enemy, so the air entering the hard drive must be filtered.

All disks in the HDD are mounted on a rotating shaft. Each disk is parallel. Each disk has a head on the storage surface. The distance between the head and the disk is only 0.1 μm to 0.5 μm, and the higher level reaches 0.005 μm to 0.01 μm, all heads are connected to the head controller, and the head controller is responsible for the movement of each head.

The above is the content of the hard disk, I hope it will be helpful to everyone.
