Writing Sequentially and Effectively

Understand how writing sequentially alone is insufficient for disk performance. Explore how log-structured file systems buffer data in memory segments and commit large, contiguous writes to enhance efficiency and reduce latency during disk operations.

We'll cover the following...

Write buffering

Unfortunately, writing to disk sequentially is not (alone) enough to guarantee efficient writes. For example, imagine if we wrote a single block to address AA, at time TT. We then wait a little while and write to the disk at address A+1A + 1 ...
