Emmc 5.1 Vs Ufs 2.2 Speed |top| Jun 2026

Before we dive into speed tests, let's understand what these technologies are.

This is the heart of the debate. Let's look at theoretical sequential and random read/write speeds. (Note: Actual speeds vary by NAND quality, but these are industry averages.)

: UFS 2.2 specifically includes a "WriteBooster" feature that significantly improves write speeds compared to earlier UFS versions like 2.1. App Responsiveness
