5 out of 5 eggsQuick, easy, forget about it.

Pros: Server 2008R2 auto installed drivers, no issues since. Been using it for over a year without issue, pulling around 120 MB baseline doing XCOPY / ROBOCOPY commands. Running two 2tb drives synced to each other for data backups.

Cons: Nothing bad to say but I had to fill this spot with a minimum amount of words.

Other Thoughts: I would recommend to anyone!

1 out of 5 eggsJust does not work with WIN 7-64

Pros: Easy to install, nice driver install, updated driver available on SIIG web site.

Cons: It does not work. Supplied driver or updated driver, it just does not work. One device installed (self-powered) or four (self-powered) devices...does not matter...nothing comes up in Windows 7-64. Useless.

Other Thoughts: Big hopes, crashed with a sledge-hammer.

5 out of 5 eggsUSB on Windows 8 broken

Pros: This device is using the Renesas Electronics USB 3.0 host controller and works excellent on XP and Windows 7 but USB 3 on Windows 8 is an known issue but it's not due to this card it's due to Microsoft and Intel not supporting it properly on Windows 8

Cons: None, even had a signed driver for Windows 7 x64

1 out of 5 eggsMight work with Windows 8

Pros: Nice packaging - BUT see Cons.

Cons: Did not work with windows 8

Other Thoughts: I contacted SIIG four times in an effort to get this thing to work with Windows 8 - once we thought it was installed, but on a reboot it no longer worked. Additional attempts to get it to work failed. Tech support at SIIG tried, but I'm not sure he was fully informed as to Window 8 install problems.
Based on internet chatter it looks like others are having the same problems installing this card when using Windows 8.
