Larger sectors enable the integration of stronger error correction algorithms to maintain data integrity at higher storage densities. Advanced Format is also considered a milestone technology in the history of HDD storage, where data has been generally processed in 512-byte segments since at least the introduction of consumer-grade HDDs in the early 1980s, and in similar or smaller chunks in the professional field since the HDD’s invention in 1956. 512-byte-per-sector format used in hard disk drives. Without revolutionary breakthroughs in magnetic recording system technologies, areal densities, and with them the storage capacities, hard disk drives were projected to stagnate.
IDEMA Long Data Sector Committee in 2000, where IDEMA and leading hardware and software suppliers collaborated on the definition and development of standards governing long data sectors, including methods by which compatibility with legacy computing components would be supported. In August 2005, Seagate shipped test drives with 1K physical sectors to industry partners for testing. In 2010, industry standards for the first official generation of long data sectors using a configuration of 4096 bytes per sector, or 4K, were completed.
All hard drive manufacturers have committed to shipping new hard drive platforms for desktop and notebook products with the Advanced Format sector formatting by January 2011. 512-, 520- or 528-byte sectors.
