Advanced Format disks use 4,096-byte sectors rather than the more common 512-byte sectors. This change is masked by firmware that breaks the 4,096-byte physical sectors into 512-byte logical sectors for the benefit of the operating system, but the use of larger physical sectors has implications for disk layout and system performance. This article examines these implications, including benchmark tests illustrating the likely real-world effects on some common Linux file systems. As Advanced Format disks have become the norm, understanding how to cope with these disks is a vital skill for anyone who wants to avoid serious performance penalties associated with suboptimal configuration.
