Sonnet Allegro Pro Reviews

Solved More than One Issue

I originally did not want to spend the money for this card and instead opted for an external USB hub. What a mistake. The external hub created nothing but havoc. It completely messed up my wifi due to interference and, of less importance, created an ugly pile of wires. I sent it back and bought this card. It's perfect. No more wifi interference and a much cleaner desktop. It was super easy to install too! Win-Win-WIn!

When I installed the card and connected 4 6TB drives to it, the card would not work. It was not easy finding the secret sauce to enable it; but the answer was eventually discovered in a FAQ at: http://www.sonnettech.com/support/kb/kb.php?cat=546&expand=_a2&action=b1149#b1149 Add Linux boot parameter: pci=disable_acs_redir=pci:12D8:2308

Asked by: Morad
It is an issue with all PCIe USB 3 cards. 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. All versions of macOS report the disconnect message; it doesn’t matter whether the year..

Asked by: Gerard
This person did not answer the complete question. I know it will work in a Mac Pro, but I want to know if it can be installed in any of the bus lanes internally. The original card is in the 4X lane and it's a half size.

The Specs says boot support- specifically will it boot a 5,1 MacPro (OS 10.12.6?
Asked by: Gale
Yes, I understand that it is compatible with OS 10.12.6 and later, but that was not the question. The question was: will the card boot from an external drive attached to it? Your specs say boot support, but the manufacturer doesn't mention it.
