Introduction

This article describes how to benchmark various storage media on the Maivin platform.

Requirements

• Torizon for Maivin (or Development Image).
  • hdparm or sysbench (installed by default in 6.3.0+).

Instructions

Choose the media to benchmark, common devices are listed.

• internal flash device /dev/mmcblk2 is mounted as / (root)
• SD card device /dev/mmcblk1 with user-defined mount point

hdparm

For hdparm you only need to know the device name, benchmarking requires root access (sudo).  Adjust device name for the device you wish to benchmark.

hdparm -tT /dev/mmcblk2

This should generate output such as this.

/dev/mmcblk2:
 Timing cached reads: 2344 MB in 2.00 seconds = 1172.89 MB/sec
 Timing buffered disk reads: 706 MB in 3.01 seconds = 234.78 MB/sec
