IDEMA
Advanced Format (AF) is any disk sector format used to store data in HDDs, SSDs and SSHDs that exceeds 528 bytes per sector, frequently 4096, 4112, 4160, or 4224-byte sectors. Larger sectors of an Advanced Format Drive (AFD) enable the integration of stronger error detection and correction, error correction algorithms to maintain data integrity at higher storage densities. History The use of long data sectors was suggested in 1998 in a technical paper issued by the National Storage Industry Consortium (NSIC) calling attention to the conflict between continuing increases in areal density (computer storage), areal density and the traditional 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. The storage industry trade organization, International Disk Drive Equipment and Materials Association (IDEMA), r ...
