Each hot-swap drive comes with an activity LED. If the LED is lit, it indicates that the drive is powered, but
not actively reading or writing data. If the LED is flashing, the drive is being accessed.

These LEDs are on SAS or SATA hard disk drives and solid-state drives. When one of these LEDs is lit, it

controller is identifying the drive.
