SMART Statistics

Published on August 1, 2025

S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology. It’s a monitoring system built into HDD’s and SSD’s. It reports on health metrics that can be use to help predict hardware failure.

For the Raspberry Pi 5 you’ll need to have compatible hardware installed such as an SSD with the M.2 Hat as the standard microSD configuration does not have SMART capabilities.

Package installation process.

$ sudo apt update

$ sudo apt install smartmontools

Usage

Identify all drives that “smartctl” can test for.

$ sudo smartctl --scan

/dev/nvme0 -d nvme # /dev/nvme0, NVMe device

Usage – Information

$ sudo smartctl -i /dev/nvme0
