Understanding Disk Partitioning and Its Impact on I/O Performance
This article explains the physical structure of mechanical hard drives, describes how partitioning works, compares two partitioning schemes based on disk surfaces and cylinders, and analyzes their impact on seek time, rotational latency, and overall I/O performance, concluding why modern OSes favor cylinder‑based partitions.
