terabyte hard drive
What is terabyte hard drive? The terabyte can easier explained as a unit of computer memory or data storage capacity equal to 1,024 gigabytes (240 bytes) OR One trillion bytes. Terabyte hard drive means hard drive data storage capacity equal to 1,024 gigabytes. History have testimony that no technology can boast of being as eagerly anticipated as 1 Terabyte hard drives.
After long awaited and much deserved drives have altered the digital landscape forever. Mega bytes to Giga Bytes and Giga Bytes to TeraBytes. The evolution hasn’t been as steadfast as imagined. Yet, thanks to the perpendicular magnetic recording (PMR) technology, 1 TB has finally hit the floors.Everybody knows that data is recorded on hard drives platters by a write head through magnetization and demagnetization
Previously the bits recorded are placed in a linear fashion. The north south poles of the magnetic bits on the platters of the disk are not aligned linearly but perpendicularly which enables high density storage due to greater number of bits on the same platter. PMR records data by perpendicular arrangement of magnetic bits on the surface of the platter With this technology information densities of up to 1 Tbit/sq. inch (1000 Gbit/sq. inch) as opposed to100 to 200 gigabit per square inch offered by linear recording technology.
Why need terabyte?New breakthroughs in the field of digital media and recording of videos through internet and television have increased the appetite for storage
In spite of this, the need for Tera bytes was fiercely debated time and again. But with their arrival, this question seems to be out of place. Massive storage needs have forced the leading hardware companies to come out with their own 1 TB drives. Hitachi was first in this category followed by Seagate and Samsung
