The hard disk has which kinds of models, the model represents what?

1, Y: represents the product model. 4D / 4K / 4G on behalf of the Star Diamond III, 4R on behalf of the Star Diamond IV, 2B on behalf of the American Diamond II, 6L on behalf of the Golden Diamond VII, 6E on behalf of the Golden Diamond VIII, 6Y on behalf of the Golden Diamond IX; 080: represents the capacity of the hard disk in GB; L: represents the cache capacity, interface and spindle motor type.

2. The three main types of hard drives are solid state drives, hybrid hard drives, and traditional hard drives. Solid state hard disk read and write speed is fast; anti-vibration and drop resistance. Hybrid hard disk applications for faster data storage and recovery. Traditional hard disk the most basic computer memory, we often say in the computer computer hard disk.

3, the current market hard drive is mainly divided into mechanical hard drive, solid state hard drive and hybrid hard drive three types, respectively, are as follows: Mechanical hard drive is the most common and most widely used type of computer storage device, consisting of disks, heads, head controllers, disk motors, serial interfaces and other mechanical hardware.
