DiskMaster vs NEAITECH DiskHealth

DiskMaster is a free desktop application for monitoring drive health on Windows, Linux, and macOS. It reads SMART attributes, self-tests, and test logs, then calculates a health score out of 100 and shows which attributes account for deductions; performance has a separate score. It stores readings in SQLite and charts changes, with alerts for shifts such as increasing drive counters. A read-only surface scan times blocks, rereads unreadable sectors for confirmation, and maps them to sectors. DiskMaster can identify files associated with those sectors and try to rescue copies while skipping unreadable bytes. Optional repair tools include sector and filesystem repair, zero-fill, and sanitizing bad sectors the filesystem marks as free. Alerts can go to Slack, Discord, ntfy, email, desktop notifications, commands, or JSON webhooks. Its CLI exports text, HTML, JSON, and CSV reports. SATA and USB monitoring needs no third-party tools; NVMe health logs and macOS use optional smartmontools. Raw SMART access requires administrator or sudo privileges.

NEAITECH DiskHealth shows disk and volume capacity, free space, health signals, and SMART information when available. It lists support for HDD, SSD, and NVMe drives, and is described as an observation tool that does not modify disks. Users can review drive and volume status, available space, and SMART notes; the maker recommends backup or cloning if status is FAILED or space is low. SMART availability and results depend on the operating system and smartctl. The free edition is described as local and offline, with no content telemetry; logs and reports are saved only where the user chooses. Downloads include Windows and macOS installers with Python and full or lightweight Linux setup options. DiskHealth is available for Windows, macOS, and Linux. The Free plan costs nothing. Pro for one OS costs €49, paid once, with updates for one year; Suite Utility costs €129, paid once, and Enterprise costs €249, paid once. Remote monitoring is not available.
