StorageStatus monitors attached storage devices and provides relevant state information and notifications. Using this information, it is possible to watch for unusual activity (such as internal or external drives unnecessarily becoming active) that can hamper battery life. For laptop users with two internal disk drives (for example, an SSD and HDD), it may be useful to know when the rotational hard drive is sleeping, because laptops are significantly less vulnerable to movement and shocks when mechanical devices are inactive.
- Easily view power state information for connected devices (active, idle, standby, sleeping)
- At-a-glance state information is readily displayed graphically in the menu bar
- Receive notifications when devices are connected and removed
- Receive notifications when devices wake up, become idle, or fall asleep
- Log activity changes to the system console or to a specified CSV file for later analysis
- Reorganize devices via drag & drop in preferences
- Rename devices by double clicking the entry in preferences
- Option + click the menu bar icon for additional device information
NOTE: If "Put hard disks to sleep when possible" is disabled in the Energy Saver Preference Pane, full disk information is not returned by Mac OS and StorageStatus may not behave as desired.
