Note: The hard disk only comes in SATA format. Therefore, you can take it as the ultimate solution for storage and performance with budget. The SSD part is just used as the temporary storage to speed things up, and your data is saved long-tern in mechanical disk. SSHD is a logical or physical storage device that combines a faster storage medium such as solid-state drive (SSD) with a higher-capacity hard disk drive (HDD), so it is called hybrid. That’s why you can hear some noise when it is running. This kind of drive has the rapidly spinning, circular platters and a read-write head which can move across them physically and scan for your wanted data parts.
This kind of drive is made up from fixed flash memory which has no moving parts. It is also sometimes called a solid-state device or a solid-state disk.
Its full name is Solid State Drive that uses integrated circuit assemblies as memory to store data persistently. Knowing what is hard disk, let’s see some basic information about its three types. Hard disk is one of the main media of computer.įor its structure, it is composed of one or more discs, which are made of aluminum, and the rapidly rotating disks (or platters) are coated with magnetic material.įor its types, there are three common hard drive, namely SSD (Solid State Drive), HDD (Hard Disk Drive) and SSHD (Solid-state Hybrid Drive).įor its types of interface, there are three common kinds, like SATA (Serial Advanced Technology Attachment), SCSI (Small Computer System Interface), and SAS (Serial Attached SCSI).įor its main developers, there are Seagate, Western Digital, TOSHIBA, and Samsung. It is also used for retrieving digital information. What is hard disk? Hard disk, or hard drive is an electromechanical data storage device.
