DriveDx review
A focused Mac utility for SMART checks, SSD wear tracking, and external-drive diagnostics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DriveDx is a macOS utility for diagnosing and monitoring internal and external SSDs and HDDs. It reads SMART attributes, evaluates drive health and performance, reports SSD lifetime indicators, monitors temperature-related conditions, and warns about potential degradation or failure. Background checks, automatic email reports, free-space threshold alerts, and drive self-tests make it suited to Mac users who want ongoing visibility into storage health, including environments with external drives, server rooms, or data centers.
Pricing is based on one-time licenses rather than a subscription. The Personal License costs $24.99 for one copy on up to three personal computers and is intended for non-commercial use. The Family License costs $49.99 for one copy on up to six computers in the same household and for non-commercial use. A Business 2-Computer Pack costs $49.99 for installation on up to two computers. The Consultant Single User License also costs $49.99 and includes portable mode for diagnosing third-party-owned drives or Macs. There is no free plan, so the paid license structure matters for occasional diagnostics as well as ongoing monitoring.
DriveDx stands out through its focus on Mac storage diagnostics and its support for external eSATA, Thunderbolt, USB, and FireWire drives with driver support. Short and full self-tests, multi-tier warnings for warning, failing, and failed states, and SSD wear-indicator reporting give the product more depth than a basic temperature viewer. It supports Intel and Apple Silicon Macs running macOS 10.9 or newer, but its single-platform scope limits its fit for organizations managing Windows or Linux systems. Choose it for detailed Mac and external-drive monitoring; choose another option if cross-platform coverage is essential.
