756 Do the Sonnet USB 2.0 or USB 3 cards support the Apple SuperDrive?Apr-02-22
759 My bus-powered USB 3 drive or SSD will not reliably mount or transfer data.Dec-14-19
817 Storage connected to a USB 3 PCIe card (or Tango combo card) gives an macOS error message upon wake from sleep.May-12-20
To minimize power usage during sleep, power is removed from PCIe cards. Because of this power-saving specification, a USB 3 PCIe card is unable to maintain USB port power during sleep. In macOS, this result in a storage device disconnect upon wake from sleep. The storage device 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.

1080 What is the difference between USB 3.0, 3.1 and 3.2?Apr-02-22
USB 3 is the specification revision published by the USB Implementers Forum. Dot 0, dot 1, or dot 2 is the revision level of the specification. USB 3.2 superseded USB 3.1, which superceded USB 3.0. Each version of the specification retained what was in the previous specification and added something new. USB 3.1 added 10Gbps. USB 3.2 adds 20Gbps.

Our cards have not changed. We have updated the naming on our web site to conform with the latest specification.
