"IDEMA Workgroup Completes Long Block Data Sector Standard, Enabling Continued Hard Disk Drive Innovation,
New Standard Developed in Conjunction With Hard Disk Drive and Software Industry Leaders; Results in Disk Drives With Enhanced Reliability and Performance", April 30, 2007, DataStoreX.Com

"IDEMA, the International Disk Drive, Equipment and Materials Association, is announcing that its workgroup has now finalized the definition of the Long Block Data (LBD) sector standard."

"The solution: larger physical block sizes. This means replacing the 30-year-old standard of 512 bytes-per-sector with 4,096 bytes. Large blocks not only enable improved reliability, while other important advantages result as well, including greater efficiency for data transfer (less overhead per block written and read), reduced format time and faster drive maintenance (shorter time periods to scan and defragment the disk)."
