Given a lack of chipset vendors integrating USB 3.0 support into their core logic (with the exception of AMD's Socket FM1-focused A75), motherboard manufacturers are forced to lean hard on third-party solutions. We take a few for a test drive.
In a world flooded with USB 2.0, external storage is pretty boring. The standard was really quite amazing when it emerged back in 2000. However, the technology world has a short attention span, and "up to 480 Mb/s," which really turns out to be more like "up to about 35 MB/s," became a bottleneck long, long ago. When it comes time to move high-definition movies, large audio libraries, or, worst of all, folders with lots of small files that absolutely hammer write performance, USB 2.0 almost always means starting your transfer and walking away for a while.
Transfering over USB 2.0 can be a painful experience.
The third revision of the USB standard offers transmission speeds up to 5 Gb/s, which, theoretically, represents a 10-fold performance increase compared to USB 2.0. Unfortunately, it's taking a while for end-users to realize the full benefit of what USB 3.0 can do. The USB 3.0 standard was originally announced in November of 2008. It took a year, though, for Buffalo Technology to become the first vendor to ship USB 3.0-capable external hard drives. At the time, there still weren't any motherboards equipped with USB 3.0 controllers.
Slowly but surely, we've seen almost every motherboard vendor incorporate third-party USB 3.0 logic onto their boards. AMD even launched its A75 chipset with integrated USB 3.0 support (a capability that Intel still lacks).
NEC Electronics (now Renesas Technology) had the first add-on USB 3.0 controller. If you wanted SuperSpeed functionality, there was one game in town. Now, there are more options.
We've already spent some time looking at the devices you plug into USB 3.0-capable controllers (Not All USB 3.0 Implementations Are Created Equal). But, should you also care about the controllers themselves? We have solutions from ASMedia, Etron, and AMD's own A75 integrated controller.

Well, at least the article showed that it's possible to reach 150 MBps write speeds and higher... good enough for me. Now all I need is a USB 3.0 drive
I've tried eSATA and found out it's not as user friendly as USB.
You will need a external power source if the eSATA isn't self powered.
Then you will also have to setup the right bios config or the eSATA won't
work properly like it's suppose to and basically the eSATA drive becomes a internal cause you lose the ability of hot plugging and swapping.
What? Even internal drives can be hot plugged and swapped. OS recognizes both internal and external sata drives alike. Once you connect it just go into My computer > manage > devices and search for new drives. To unplug simply right click on that drive and click disable. Even this can be done with IDE (ATA) provided you don't use old P4 era motherboards.
1.) Motherboards with hot-plug capability to internal drives were available almost from the beginning. Nvidia was famous for adding this function to its drive controller firmware, and ASRock was famous for adding it to the drive controller firmware of boards with other chipsets.
2.) To this very day, the ports of many NEW motherboards STILL lack firmware support for this function on at least some of the ports. A few lack hot swap firmware on all of the ports, and a many have this feature selectable in BIOS.
So, even though you're part right, the person you responded to is more right.
Thanks for filling me. Coincidentally I never came across motherboard that doesn't support hot plugging out of the box that's why I thought everyone supports it.
If SATA is set to AHCI it'll support hot-swapping if it's set to ATA/Legacy it will not.
USB 3 power management seems to cause issues. With it enabled, I got really slow speeds (using a USB 2 HDD though, just out of curiosity). With it disabled, I got the same speed as the USB 2 controller.
I have an external drive which has eSATA, USB 2.0 and Firewire. I'm using it on USB 2.0 for this very reason: hot plugging/swapping.
