Hard Disk Drive - Rigid Magnetic Platters, 1tb Storage Capacity, High-speed Data Retrieval And Non-volatile Memory

We are praised company for importing and exporting huge range of Hard Disk Drives from Surat, Gujarat, India. A hard disk drive (HDD), hard disk, hard drive or fixed disk[b] is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces.[2] Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory, retaining stored data even when powered off.

Introduced by IBM in 1956,[3] HDDs became the dominant secondary storage device for general-purpose computers by the early 1960s. Continuously improved, HDDs have maintained this position into the modern era ofservers and personal computers. More than 200 companies have produced HDD units, though most current units are manufactured by Seagate, Toshiba and Western Digital. As of 2015, HDD production worldwide amounts to multiple exabytes per year and is growing, although unit shipments are declining. Arial storage density of hard disks is increasing as newly developed materials and manufacturing techniques advance.
