Upgraded my 7 year old PC with a cheap SIIG card a few years ago and after a while it developed glitches like dropping connections, and it was just slow to begin with. Looked up the chipset and found every card using those chips had problems. This Sonnet is just stunning, especially considering the age of my system. I get over 200MB/s on a Sandisk high speed reader with an Extreme Pro 300MB/s SD card (which seems to be average even for much more modern computers). A Sandisk Extreme external SSD gets pretty close to 300MB/s. Each port has its own controller, so I guess if one port develops a glitch the others should still be fine. So far I couldn’t be happier.

I use a number of external drives, so I needed more than the 4 USB 3.0 ports on my Dell Precision workstation. This card arrived quickly, installed easily and I’m very happy with the speed.

No problems with this ‘plug ‘n play’ device in a Classic Mac Pro 5’1. The extra controller makes for quicker transfers. To utilise this device for quickly copying external SSD’s remember the correct cable orientation – SSD to SSD : in ports 1 and 3 (or 2 and 4).

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

I have been having occasional issues with external TB3 Docks on my 7,1. This card seems to have solve all my random crashes apparently tied to those docks.

This was a great addition to the computer and super easy install. Just power it off, slide the card in and powered it on. The BIOS recognized it and Windows automatically downloaded the drivers it needed. I couldn’t be happier. The installation instructions were really sparse, practically useless though. If you’re a novice: yes, it really is that easy.

Easily popped it into a new Sonnet Echo Express III-D Desktop Thunderbolt 2 Expansion Chassis. All ports working as expected on things like keyboards, a headset, etc. However, have had a few issues with a couple of different drives (one USB powered, one not) not mounting and an iPad and iPhone not getting recognized/charging. I have not had it long enough to troubleshoot/research/solve those issues before needing to leave for a month on a project I am on while writing this. I’m guessing it is an issue of the amount of power the card is serving up to the 4 ports. Although the Sonnet chassis has an internal power connector to attach to cards needing it, it was not a direct fit with anything on this card. The issue of power was not mentioned in any straightforward manner out of the box. As I said I need to research it further …
