Coding for SSDs – Part 2: Architecture of an SSD and Benchmarking

This is Part 2 over 6 of “Coding for SSDs”, covering Sections 1 and 2. For other parts and sections, you can refer to the Table to Contents. This is a series of articles that I wrote to share what I learned while documenting myself on SSDs, and on how to make code perform well on SSDs. If you’re in a rush, you can also go directly to Part 6, which is summarizing the content from all the other parts.

In this part, I am explaining the basics of NAND-flash memory, cell types, and basic SSD internal architecture. I am also covering SSD benchmarking and how to interpret those benchmarks.
