Welcome back friends! I hope you will be enjoying the posts. Today we will discuss some more terms relating to hard discs.
SATA: (Serial Advanced Technology Attachment) Like IDE cable it is also used to connect hard discs and CD/DVD Drives to the port on the motherboard. It is serially communicating interface that means data travel on it in the serial mode i.e one after another. works faster than the conventional parallel cables and is also longer than the IDE cables but less in width. It may be up to 1.5 meters long. A SATA cable may support speed of 150 to 300MBps (Mega Bytes per second).
SCSI: (Small Computer Sytem Interface) :It is an advanced version of IDE/ATA interfaces. It is used to optimize data flow and is system level bus with controllers on each SCSI device.
RPM: (Rotations per minute) The speed of the platters in the hard drive is measured in rpm. The platters are mounted on a spindle. Faster the spped better the hard drive as it effects over all speed of a computer. Most common speed of the hard drives these days is 7200 rpm where as for a laptop it is 4200 rpm.
Platters:These are the flat round discs usually made of very thin soft plastic and coated with magnetic material. These are used to actually write/record and read the data with the help of magnetic heads just like the tape recorders earlier used to record and play the songs and music.
In the next post we will discuss some more aspects about the hard discs. Enjoy reading till then.
