| 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. |

| What versions of macOS support Allegro USB 3 cards? | Apr-02-22 |
| All Sonnet Allegro (and Fusion Dual 2.5" SSD RAID) PCIe Cards use a macOS pre-installed driver.
These cards are compatible with macOS 10.10 in the MacPro 3,1; 4,1 & 5,1 and in Thunderbolt 2 Expansion chassis.
These cards are not compatible with macOS 10.11, due to a bug in the Apple driver.
These cards are compatible with macOS 10.12 (2)-10.14 in the MacPro 5,1 and in Thunderbolt 2 & 3 Expansion chassis.
These cards are compatible with macOS 10.15-macOS 12 in the 2019 Mac Pro and in Thunderbolt 2 & 3 Expansion chassis.
-------------------------------------------------------------------------------------------------------------------------
Notes:
- These cards are not compatible with Thunderbolt 1 expansion chassis.
- macOS 10.12 erroneously reports a 5Gbps connection when connected at 10Gbps.
- The maximum Apple-supported OS for the Mac Pro 3,1 and 4,1 is OS X 10.11. Dosdude1 offers patchers to allow installation of newer versions of macOS. The Apple USB 3 driver in these patched newer versions will support the Allegro cards.
- Performance of the Allegro cards may be limited by the Mac Pro 5,1 PCIe 2.0 bandwidth.

| Why does Sonnet use only PCIe 2 to connect the two controllers on these 4-port USB 3.2 Gen 2 cards? | Apr-18-21 |
| We connect each USB 3 controller with two lanes of PCIe 2. Each controller has 1000MB/s bandwidth which is enough bandwidth for the fastest devices you can connect, such as USB 3.1 Gen 2 NVMe SSDs. Because the read/write bandwidth is independent, on one controller you can be reading from one SSD at 1000MB/s, and writing to another at 1000MB/s, plus the same on the 2nd controller for an aggregate transfer rate of 4000MB/s. What makes this possible is that Sonnet uses the advanced ASMedia 3142 Controller that supports Multiple INs, which means that reads can commence on one port before a write has competed on the other port.
A PCIe 3 Bridge chip would cost you $50 more, but would give you incremental performance only if you needed to continually simultaneously read--or simultaneously write--to four USB 3.1 Gen 2 NVMe devices, a very unusual use case.
