Idema new standard for hard disk drive : Idema, the International Disk Drive and Materials Association, today announced the results of an industry committee assembled to identify a new and longer sector standard for future magnetic hard disk drives (HDDs). This Committee recommended replacing the 30 year-standard of 512 bytes with sectors having ability to store 4096 bytes. Dr. Grochowski, director of Idema US, reported that adopting a 4K-byte sector length facilitates further increases in data density for hard drives which will increase storage capacity for users while continuing to reduce cost per gigabyte. "Increasing areal density of newer magnetic hard disk drives requires a more robust error correction code (ECC).
