756 Do the Sonnet USB 2.0 or USB 3 cards support the Apple SuperDrive?Apr-02-22
None of Sonnet's Cards with USB 2.0 or USB 3 (either Type A or Type C) ports support the Apple SuperDrive. You must use a built-in USB 2.0 or 3.0 port on your Mac.

According to http://support.apple.com/kb/HT5630, "The Apple USB SuperDrive is compatible with Mac models from 2008 and later that don't have a built-in optical drive."

1097 The Fusion Dual 2.5" SSD RAID PCIe card gives an macOS error message upon wake from sleep.Mar-30-20
To minimize power usage during sleep, power is removed from PCIe cards. Because of this power-saving specification, the controller on the Fusion Dual 2.5" SSD RAID PCIe card is unable to maintain its port power during sleep. In macOS, this may result in the SSD RAID disconnecting upon waking from sleep. The SSD RAID will automatically remount, but the system reports a disconnect message. Because macOS flushes all caches before sleeping, this disconnect should never result in any loss of data.
