Brand new Mac Studio and new Pegasus 32 (64 TB). All operational and installed correctly. Quite often, Pegasus drives spin up and eight blue drive lights on enclosure start the flicker, as if copying data. Drives then power down (fan continues to run for some time) then process begins again at some point later. Mac is in sleep mode (low power state, display off, even though it may perform some tasks in background.) Online forums report similar issues but typically involve Pegasus 2 and 3 units. If you have experience with this this issue with the 2024-2025 Mac Studio, suggestions are welcome. See Mac attached energy settings.

Hello Kirk,
Most likely the mac is silently waking from sleep to do various functions like checking for new mail. When the mac wakes up, it also wakes all external devices such as the Pegasus. The Pegasus does not control it's power state, the mac does.
The Energy tab in the settings app is where you configure the power options.
