先进格式化（英文：Advanced Format，简体中文：高级格式化，繁体中文：先进格式化\高端格式化\高端格式化）是IDEMA（International Disk Drive Equipment and Materials Association）于2009年12月制定的硬盘格式化标准。IDMEA在2005年与Hitachi、Seagate、WD、LSI、Intel、Microsoft、Dell、HP、Lenovo等硬/软件厂商制定出1024字节、2048字节和4096字节三种容量磁区配置，先进格式化是规范中的4096字节（4KB）配置。从2011年1月1日起，硬盘厂商新推出的硬盘，都将遵循先进格式化（4KB）的设计。

Advanced Format is a generic term pertaining to any disk sector format used to store data on magnetic disks in hard disk drives (HDDs) that exceeds 512 to 528 bytes per sector, such as the 4096-byte (4 KiB) sectors of the first-generation Advanced Format hard disk drives. Larger sectors use the storage surface area more efficiently for large files but less efficiently for smaller files, and enable the integration of stronger error correction algorithms to maintain data integrity at higher storage densities.
