Coloured LED indicators in your menu bar showing real-time disk read and write activity. Know exactly what your drives are doing.
Download on the Mac App StoreColoured LEDs in your menu bar blink green for reads, red for writes, and blend for simultaneous activity. Adjustable size, spacing, and sensitivity.
Measure sequential read and write speeds across all connected drives using direct I/O that bypasses the file cache for accurate results.
Fire random-sized reads and writes at your drives simultaneously. Configurable duration, min/max I/O sizes, and per-drive statistics.
Customise read and write colours for each drive so you can tell at a glance which disk is active. Colours persist across sessions.
Ramps up to 15Hz during activity and decays to 1Hz when idle, keeping CPU usage minimal. A sensitivity slider gives you control.
Eject external drives directly from the menu. DiskLED releases its monitoring handles first to ensure a clean unmount.
A DiskLED user discovered their external SSD was running dramatically slower than expected. The Speed Test showed read/write speeds far below the drive's rating. The culprit? A USB-C charging cable that looked identical to a data cable but lacked the high-speed data lines.
"Not all cables are the same although they look the same."
