StorageStatus at Mac App Store analyse

StorageStatus monitors attached storage devices and provides relevant power state information and notifications. Using this information, it is possible to watch for unusual activity (such as devices unnecessarily becoming active), which can hamper battery life.

Further, StorageStatus automatically wakes all disks within a software RAID volume and devices within custom wake pools, thereby improving spinup times and reducing delays.

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.

FEATURES
- 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
- Prevent specific devices from falling asleep
- Access sleeping RAID volumes more quickly with automatic waking of software RAID disks
- Create custom wake pools to ensure a custom pool of devices wake simultaneously
- 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

Some devices may not be initially compatible for the sleep prevention and disk waking features if they do not support SMART attributes. Full functionality is possible via a helper utility.

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.
