The hard disk in if one is a storage device that digitally stores the data codified in plates turning quickly with the magnetic surface. its types next: IDE (Integrated Device Electronics)/LEG (Parallel Advanced Technology Attachment) These hard disks used to be but the common ones for all the equipment. It is possible that we know them better like discs IDE or EIDE. IDE and EIDE talk about the type of interface that is used to connect the hard disk of its computer. In order to connect them, 40 or 80% of the wire of the tape are used that connects to the motherboard of the interior of the PC. As the technology LEG was implemented, it transfers information and data with more speed.
For this reason, some discs to use 40 cables and some use 80. Although still this type of discs, the majority of people can be bought now to decide on type SATA. Also it will find smaller hard disks of 2,5 inches IDE or LEG within the portable computers. SATA (Serial ATA) (Serial Advance Technology Attachment Drive) In comparison with a disc LEG, the connections in the SATA are totally different. That goes for the connection of data, as well as the connector of feeding of energy. In the industry of the computers, the speed is the key factor that the majority of people looks for. discs SATA were created to provide great amounts of data to very fast speeds.
The later models of discs LEG have a rate of speed of similar transference, but most recent, the thinnest design of units SATA allows one better use of the technology and therefore it provides more speed to hard disks. In addition, they also use less energy, than it is an important requirement for the majority of the computers and modern operating systems. SCSI (Small Computer System Interface) could be thought that hard disks SCSI are similar to LEG, but differ in several forms.
