UFS 2.1 Storage Benchmark with KM5P8001DM-B424

Introduction

Modern embedded systems require faster and more reliable storage solutions to support operating systems, large data processing, and edge computing applications. Traditional storage interfaces often become a bottleneck when handling high-speed data workloads.

In this project, we explore the performance of the Samsung KM5P8001DM-B424 uMCP memory module by building an embedded storage evaluation platform and measuring its UFS 2.1 storage capabilities.

The goal is to understand how high-speed embedded memory solutions can improve the performance of industrial terminals, edge computing devices, and smart embedded systems.

About KM5P8001DM-B424

The KM5P8001DM-B424 is an integrated memory solution combining:

64GB UFS 2.1 storage
32Gb LPDDR4X memory
Compact uMCP package design

By integrating both storage and memory in a single package, uMCP solutions reduce PCB space requirements while providing high-speed data access for compact embedded devices.

System Architecture

The evaluation platform consists of:
