A story that began as storage keeper of computer computer hard drives have today with speed and performance added the dimension of portability. Yes this is the story of hard disk drive. Commonly referred to as HDD in the technical circuit, it is the main storage centre in the computer. It is larger and faster than the other storage devices like PD/CD/DVD.
When need changes and when they become a demand, then the by-product is evolution. Just sitting inside the computer and doing the storage job was not enough; you need to go out and reach out to the new needs cropping up. Thus, the device external hard drive was born; so what remained inside the computer was called the internal hard drive and what could go about places and store came to be known as external hard drive. So now we have two types of computer hard drives: internal and external.
That was the ABC on computer hard drive, HDD. Today HDD is used in devices using data such as desktop computers, camcorder, supercomputer and mainframes. You know something? There are hundreds of them in built in the supercomputer and the mainframe.
The performance of the computer depends on the speed of the hard drive, after all thats what affects the speed of the computer when it boots up and loads the programs. In doing so, there are many programs that need to be run simultaneously without affecting the speed or performance, so here is where you need your computer hard drive to be good with multitasking.
The serial interface passes the data from the HDD to the computer; to get this done faster several serial interfaces are deployed. Today HDD operates on high-speed serial interfaces: Serial ATA (SATA or Serial Advanced Technology Attachment) or Serial attached SCSI (SAS) (Small Computer Serial Interface, Serial attached).
One question: Who needs this speed, this performance? Ok if we are out of the Flintstones world then yes computer gaming, sound, video, graphics, and huge database(s) to run these behemoth tasks, do need a performer not a doer.
