A cheaper card might lag, stutter, or not work at all - particularly with video. It's well worth an extra 20 dollars for a card that works well.
One caveat is that this card requires a sata/molex power cable, but only if a device is not detected or all ports are used simultaneously. For most people neither condition will occur. Unfortunately the manufacturer does not include this cable, but it can be purchased for 2 to 3 dollars on Amazon. So you might want to get one while you're here if you're going to draw a lot of power.
The following I pasted directly from SIIG's website:
SIIG's DP USB 3.0 4-Port PCIe i/e is a high performance adapter card designed to instantly add four additional USB 3.0 ports (1 internal and 3 external) to your PCIe-enabled desktop computer. Its USB 3.0 interface delivers ultra-fast USB 3.0 data transfer rate of up to 5Gb/s, and allows you to hot-swap devices (connect and disconnect) without first turning your system off. It supports per port over-current protection to protect connected devices and the board itself from unforeseen power surges, offers backward compatibility for USB 2.0 and USB 1.1 devices and supports the simultaneous operation of USB 3.0, USB 2.0 and USB 1.1 devices. This dual profile USB 3.0 4-Port PCIe host adapter works with a wide variety of high-bandwidth USB 3.0 devices, including USB 3.0 hard disk drive enclosures, high-resolution webcams, video surveillance cameras, digital video cameras, and multi-channel audio devices.Read more ›
I noted all positive reviews for the SIIG product on the Amazon site and others and it had a Texas Instruments chip which I could not find on any other card. The price for similar items having other chips is consistently less than this SIIG product, but some reviewers of PCIe cards having various other chips have noted problems with disappearing drives similar to my experience.
This card was easy to install and had printed, easy to follow directions. A Molex to SATA adapter cord is not included in the package to power the card but this was not a problem for me because I had a free SATA male plug available from my computer power supply. SIIG states one may not need to power the card with the SATA connector but I installed it that way from the get go.
My drives consistently perform well with the SIIG card. Downloads complete without issue, big files transfer rapidly, movies play without lockup and the drives do not drop from Windows Explorer. The card is installed on a PC running 64 bit Windows 7.
Although it is priced a bit higher than similar products, it performs like it should and I recommend this product to anyone wishing to add high speed USB 3.0 connectivity to their machine.
Update March 2014: Continues to perform perfectly with Windows 8 and 8.1. No problems with Microsoft's new operating systems. Works with either the USB 3.0 driver native to Windows 8 or the driver provided on the SIIG website.
There's a fantastic review here by 'danno46' that's very in depth, so I won't repeat all his info, it is accurate. I'd like to comment on the purchase experience, install, and how we use the card.
Like most of you, I wanted something from Amazon Prime. I looked and read reviews on over 30 cards in stock from Amazon, but this card had by far the best reviews on Amazon and on the egg (About 50 reviews there you can read as well). So I purchased from a third party vendor, through Amazon from AntOnline. I can confidently say, don't hesitate to buy from them. It was quick delivery (5 business days), and the card is worth it.
Briefly on the card & installation:
It uses the TI (Texas Instruments) chipset which is bulletproof, and justifies the higher price as it just works. I installed in an older Dell Optiplex Desktop running Windows 7 Enterprise 64-bit. This card needs power to give full USB 3.0 potential, and uses a SATA power connection. You'll likely need either a SATA power extension cable (8" to 12") to reach the card, I bought this one: ...Read more ›
