smartmontools review
Broad, free disk-health monitoring for technical users comfortable with command-line tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
smartmontools is an open-source package for monitoring and controlling storage-device health through SMART data. It combines smartctl, a command-line inspection and device-control utility, with smartd, a daemon that periodically polls drives. The package is aimed at administrators and technically proficient users who need storage-health checks across Linux, macOS, Windows, BSD, Solaris, and other documented operating systems. It reads SMART data from ATA/SATA, SCSI/SAS, and NVMe devices, making it a fit for environments with varied storage hardware.
The package is free and open source rather than divided into paid tiers. Its monitoring scope includes SMART error and attribute-change logging, drive self-tests, failure-status monitoring, temperature tracking with configurable thresholds, CSV attribute logging, and per-device JSON state files. Configurable email warnings can report detected disk problems, while SYSLOG and Windows Event Log provide additional integration points. The documented platform coverage also includes FreeBSD, NetBSD, OpenBSD, Cygwin, OS/2, eComStation, and QNX, alongside Linux, macOS, Windows, and Solaris.
Its main trade-off is the command-line operating model. Users who are comfortable configuring smartctl and smartd can access broad device support, periodic polling, SSD wear tracking, temperature alerts, and failure-status monitoring in one open-source package. Those seeking a graphical workflow or a simpler onboarding path should choose a disk-health tool designed around a visual interface instead. smartmontools is a strong choice for technical users managing mixed operating systems or storage devices, while its utility is less suited to users who want dashboard-led monitoring with minimal configuration.
