22) Hard Drives Connections (Sata, IDE) Technologies (HDD, SCSI, SSD, SSHD).
-SATA: (Serial ATA) is the one currently used by desktop and laptop computers of the latest generation, it is a novel interface that uses a serial bus for the transfer of data of course faster and more efficient than the IDE system
- IDE: is a unit that uses a parallel ATA connection, called IDE informally. The term IDE is synonymous with Integrated Drive Electronics Interface (Integrated Electronic Unit Interface). The first time the hard drives used the IDE interface was in 1986.
- HDD: Ó Hard drives are conventional hard drives, their acronym comes from the English "Hard Disk Drive", this technology is the oldest of the three since it is the only one that requires mechanical movement to function.
The hard disk works in the following way, inside it has a magnetic head that goes encoding tiny sectors of a metallic disk in rotation at high speeds, these heads write on the disk using binary code (0 and 1).
-SSI: Small Computer System Interface Small computer system interface, better known by the English acronym SCSI is a standard interface for the transfer of data between different devices of the computer bus.
- SSD: or disk in solid state The SSD or disk in solid state are the natural evolution of the HDD technology or hard disk, the discs in solid state do not require of mechanical movement with which they do not heat so much, make less noise and require less energy
The SSDs use the same SATA connector as the HDD, despite this they achieve much higher speeds reaching 6Gbps (540 MB / s) of read and write.
-SSHD: Solid state drive (SSD) + hard disk drive (HDD) = Hybrid solid state drive (SSHD) and innovation. Hybrid solid-state drives (SSHD) combine a small, fast, and affordable amount of NAND-type flash memory with a traditional hard drive
