NEAITECH DiskHealth vs smartmontools

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.

smartmontools is a free package containing smartctl and smartd for controlling and monitoring storage devices through SMART. It supports ATA/SATA, SCSI/SAS, and NVMe disks, as well as SCSI/SAS tape devices. smartctl can report SMART health status, show capabilities such as error logging and offline surface scanning, display vendor-specific attributes, start device self-tests, and read their logs. A failing health status can mean a device has failed or predicts failure within 24 hours. smartd periodically monitors SMART status, error and self-test logs, and attribute changes; it can schedule tests and report errors and attribute changes to syslog. It also supports warning emails and executable commands. The project says it should run on modern Linux, BSD variants, macOS, Solaris, Windows, Cygwin, OS/2, eComStation, and QNX systems, and can run from various Live CDs and DVDs. The package uses the GNU GPL Version 2 license and was originally derived from the Linux smartsuite package. Its capabilities focus on SMART health reporting, testing, and ongoing monitoring.
