Uncovering SD card Performances using Bare-Metal Benchmarks

In this article, we present a detailed discussion of SD card performances along with benchmarks for consumer and industrial-grade cards. The results help quantify the large variations in performance between individual devices and their impact on real-world performance.

QSPI NOR Flash Part 3 — The Quad SPI Protocol

Over the course of this article, we’ll go through the variations of the protocol used by QSPI NOR Flash devices. We’ll start simple, with the basic SPI protocol then move through the variations to reach some of the more complicated QIO, QPI and DDR variations.
