Aman Disk

Features

NVMe and ATA/AHCI health: reads S.M.A.R.T. data from NVMe SSDs, Apple PCIe AHCI SSDs and SATA drives, with a clear status (“Healthy”, “Needs attention”, “Likely failing”) and the remaining life when the drive reports it. Attributes explained: every S.M.A.R.T. attribute has a readable name and an explanation; values are converted to their unit (°C, hours, TB), or shown as raw hexadecimal on request. Temperature history: one reading every 30 seconds, kept at full resolution for 24 hours, then as averages for 30 days; charts over 1 hour, 24 hours, 7 days and 30 days. Each reading adds about 170 bytes to the history, so the app doesn't wear out the drive it watches. Performance test: sequential and random reads and writes, with large and small blocks at several queue depths. The test file is always deleted. Menu bar: status and temperature of each internal drive, with the last hour's curve. The app can stay there when its window is closed. Live Dock icon: the ring around the icon follows the health of the startup drive. Alerts: a notification when a drive changes status, stays too hot, or drops below 50%, 25% or 10% of its life (off by default). Reports: PDF, text or JSON export, with the serial number masked by default. English and French interface.
