4 out of 5 eggsWorks good

Pros: Small, molex power not required unless you're powering something, seems to work good so far. It appears to be well made and has a nice finish to it.

Cons: I wish the included sata -> molex cable was a bit longer. If I end up having to use it in the future its going to be hanging right across the CPU fan. No big deal for my application but someone who was cable managing might have some trouble with it.

Other Thoughts: Card worked without any trouble in my home server. HP ML110 G6 with windows 7 pro x64. Makes for backing up 2+TB of data a bit easier than USB 2.0 - hope to get some solid life out of it.

5 out of 5 eggsWorks as advertised

Pros: Controller works as promised with better performance. Works with both Server 2008R2 & Win7-64.

Cons: None really.

Other Thoughts: I ran some benchmark tests after getting this controller running on an ASUS P5Q Deluxe board. Older board for sure but worked fine on both OS’s. Tested using the following disks using both PassMark & CrystalMark.

Disk1 – Seagate USB3 STDR2000100 portable
Disk2 – Transcend USB2 TS1TSJ25M2 portable connected to USB3 controller
Disk3 – Transcend USB2 TS1TSJ25M2 portable connected to onboard USB2

CrystalMark PassMark
Disk1 = 110.30 MB/s 34.18 MB/s
Disk2 = 36.60 MB/s 13.78 MB/s
Disk3 = 32.20 MB/s 9.92 MB/s

So, you can see I am getting between 14%-39% improvement just with this controller depending upon the test used. Switch to a USB3 disk and I’m getting 343%-345% improvement over a USB2 disk and motherboard controller. For $30 am quite happy.

1 out of 5 eggsVery VERY unreliable!

Pros: Price

Cons: You get what you pay for - cheap UNRELIABLE adapter. I've had 2 of these installed in Windows 7, 8, 8.1, Small Business Server 2008, and Server 2012 R2 - always the same problem - the controller freezes with the only solution to reboot the system

I've updated the firmware on these - the problem remains - freezes sporadically

5 out of 5 eggsWorks very well with Win 8.1 64bit

Pros: Purchased several USB 3 PCIe adapters to use on Win 7 64 bit and on Win 8.1 64 bit. This is the only one that works on Win 8.1 64 bit! Use win 8 native drivers.

Cons: Needs more ports

4 out of 5 eggsGreat Performance with One Flaw

Pros: - Fantastic Performance
- Easy Install
- Took 3 seconds to copy a 745mb ISO from OCZ Vertex 4 SSD to a 16gb USB 3.0 Sandisk Extreme memory stick

Cons: - Mine needed firmware update which was not easy to find
- Best drivers are not on StarTech's site. I had to go to Renesas site to obtain them.

YOU CANNOT BOOT FROM USB DRIVES ATTACHED TO THIS CARD (i hear you can if you have a UEFI bios)

I also need to point out that a previous reviewer claimed the reason why you cannot boot from a device attached to this card is because the driver isn't loaded and tried to say this was somehow like a video card requires drivers.

NONSENSE.

If that were the case, you wouldn't be able to boot from PCI-Express SATA cards, or old school PCI-Express IDE/Firewire cards. Well... you can! The reason why this card cannot be booted from is due to the card not having a boot rom chip which allows the bios to understand what kind of device it is and how it works. Think of it as a driver that's built into the card. ALL bootable devices, including video cards and just about every storage controller in your computer have their own little boot ROM, which is why many motherboard manufacturers include updates for these boot rom chips on occasion as part of a BIOS update.

All too often I see people on Newegg select the highest level of tech experience when they are nowhere near it. What I posted about boot roms is very basic knowledge that even a moderately skilled person should know and understand.

5 out of 5 eggsAnother solid product from StarTech - I'm getting used to that :)

Pros: - works in Windows Server 2008 R2 (64-bit), plugged into PCI Express x16 bus (though it requires only PCI-E x1, which my server was out of)
- trivially easy installation from the CD. if only all storage controllers installed so smoothly....
- throughput - on a 4+ year old motherboard from Gigabyte, it allows minimum of 110-120MB/sec sustained read performance on my USB 3.0 storage devices (USB 3.0 ThumbStick, Seagate 500GB 2.5" external backup, Corsair AirVoyager 1TB 2.5" external backup); I didn't test write throughput, but I expect to see numbers comparable to eSATA-connected devices.
- I owned another StarTech product, 2x eSATA ExpressCard for my laptop, for over 3 years, and found that one very reliable (the manufacturer even included a piece of plastic stabilizing the narrow card in a wide ExpressCard socket, which was a nice surprise). it didn't quit on me yet, so I expected this PCI Express card will not quite on me too soon either.
- attractive price - the card gives me all it promises and all I want for a price I'm happy to pay.

Cons: - after plugged in and the system was booted, Windows Server 2008 R2 showed a problematic device in USB controllers section in Device Manager. I tried updating the drive automatically (from Web, Windows Update etc.) but that didn't work. I admit, I'm a little spoiled by devices that you plug in, and Windows finds drivers for them immediately (for more than 10 years, with the exception of certain printers).
Not a big deal here - the provided CD allowed smooth installation of the proper driver, with absolutely no issues. I didn't even have to go to StarTech's website to find a driver, all I needed was in the box.
- the card requires additional power, through a Molex connector. the box includes a Molex-to-SATA converter, but it's a short one, I could use one 2 times as long. I had a problem rearranging my power supply cables to provide power for this card (it's very short). Seriously, the manufacturer should assume that all Molex/SATA power cables leading from the PSU are often leading very far from the card's location (to hard drives/optical drives), so sometimes it may be impossible to provide power to the card without re-arranging hard drives in the system.
I could have also gone and bought a longer power splitter/plug converter cable, but that's an extra few $ and a trip I don't want to be wasting time on. Please provide me everything I need in the box, even if I have to pay $3-$5 more.

Alternatively there could be a cable converting power from those 6- and 8-pin PSU cables used for video cards (I'm not sure about the voltages, perhaps that's not a feasible option).

Other Thoughts: It's hard to find any real con for this product. Maybe it will quit working on me too soon, but that's not the experience I had with StarTech. I'm slowly becoming a loyal fan and remembering the brand when I talk to others about hardware-related topics.

I ordered another StartTech product, USB 3.0 ExpressCard for my laptop. My expectation is I'll see the same solid build, durability, reliability, ease of installation, and performance.

So far, despite minor glitches (most of them have to do with non-automatic driver installation) I can recommend StarTech to anyone.

5 out of 5 eggsexcellent product

Pros: Super easy firmware update, driver install for 2011 Windows Home Server. Went to web site downloaded updates for Server 2008 R2 which is the basis of 2011 Windows Home Server. Ran firmware update which auto detects firmware and updates. Same for Driver. Plugged in USB 3.0 drive and started backups.

Cons: None.

Other Thoughts: Down load driver from web site. Read notes and install instructions. Drivers must be uninstalled and any software for device unloaded before new driver installation.

5 out of 5 eggsStarTech gets Tech Star!

Pros: Installed with no problems.
I used the NEC drivers someone was kind enough to provide a link for in a past review. Driver installed without a hitch and now I am running USB 3.0 devices and loving the speed boost.

Cons: None, got exactly what I paid for, 2 fast USB 3.0 ports.

Other Thoughts: Price was agreeable, especially after reading the reviews on the competitors.

4 out of 5 eggsVery good card with bad software

Pros: Much faster than usb 2. I have a Asrock K10N78m mother board with 4 gigs of ram running Windows 7 32 bit. Big difference when sending files to a external hard drive. A backup takes much less time. Good card for the price.

Cons: The software did not work with my system. I went to StarTech's website and downloaded the latest version and my system would not recognize the card.Finally went to the chipset maker NEC and downloaded a older version and the card now works. Just a heads up if any one else has this problem with installation.
