The Interface
Explore the basic interface of modern hard disk drives by examining how data is organized into 512-byte sectors and how these sectors are read or written. Understand the concept of atomic 512-byte writes, the risk of torn writes during incomplete operations, and the performance benefits of sequential access over random block reads. This lesson guides you through the disk's address space and the practical assumptions relating to disk access speeds.

Let’s start by understanding the interface to a modern disk drive. The basic interface for all modern drives is straightforward. The drive consists of a large number of sectors (512-byte blocks), each of which can be read or written. The sectors are numbered from to ...
