SMART Statistics

S.M.A.R.T. (Self‑Monitoring, Analysis and Reporting Technology) is built into most modern HDDs and SSD’s. It provides health metrics that help predict hardware failures and track device reliability. On the Raspberry Pi 5, SMART is available when using compatible storage (e.g., SSDs with an M.2 hat), since microSD cards don’t expose SMART data.

Why SMART matters
  • Predictive maintenance : Spot failing drives before outages.
  • Baseline tracking : Monitor wear levels, temperature, and error counts.
  • Integration : JSON/CSV output makes it easy to feed SMART data into monitoring stacks.

1. Installation process.

$ sudo apt update

$ sudo apt install smartmontools

2. Usage examples

Scan for devices that support SMART using the “smartctl” utility.

$ sudo smartctl --scan
Output… 

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

3. Usage – Information

Show model, firmware, and capacity details

$ sudo smartctl -i /dev/nvme0
