Test Setup And Benchmarks

Does The USB 3.0 Controller On Your Motherboard Matter?
By

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.

Test Hardware
Processor
AMD A8-3800 (Llano) 2.4 GHz (24 * 100 MHz) CPU, 600 MHz GPU (400 Shaders), Quad-core, Socket FM1, 4 MB L2 Cache, Power-savings enabled
Motherboard
Asus F1A75-V Pro, BIOS v1102
Gigabyte A75-UD4H, BIOS vF6
Memory
Kingston Hyper-X 8 GB (2 x 4 GB) DDR3-1333 @ DDR3-1333, 1.5 V
System Drive
OCZ Vertex 3 240 GB SATA 6Gb/s, Firmware: 2.06
Graphics
Palit GeForce GTX 460 1 GB
Power Supply
Seasonic 760 W, 80 PLUS
System Software and Drivers
Operating System
Windows 7 Ultimate 64-bit
DirectX
DirectX 11
DriverGraphics: Nvidia 275.33
RST: 10.5.0.1022
Virtu: 1.1.101
Asmedia: 1.10.0.0
Etron:105
A75: 8.863
Benchmarks
Iometer
v1.1.0


Since Kingston’s HyperX Max 3.0 got high marks in our previous USB 3.0 roundup, we’re using four of them to simultaneously tax the bandwidth of each controller as much as possible (obviously we can only connect up to two drives to each controller, so the four SSDs have to be deployed across a combination of ports to tax the various controllers). This should provide a worst-case scenario, since solid-state-based USB 3.0 storage solutions deliver much more potential throughput than the conventional external drives out there.

The USB 2.0 and 3.0 standards do not include support for native command queuing, so we’re only testing at a queue depth of one.

    Asus changed the USB 3.0 controller on their P8P67 line of boards... I think they switched to ASMedia from NEC, and I'd love to see the difference between the two benchmarked. I think this article has way too few controllers; there're more USB 3.0 solutions on the market.

    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 :)

    That's why eSATA is the best for external storage. USB is great for everything other than data throughput.

    thanks for the article! i always use usb drives, most of the old drives using usb converters. good to know i can run multiple of them without hitting speed limit.

    They should have included windows 8 in this benchmark. On my system win7 writes at 3-4 MB/s to thumb drive and win8 writes at constant 10 MB/s to same thumb drive. (Everything's USB 2.0 though). Some witchcraft :D  I don't know but they should have included win 8.

    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.

    You started off right but then went soooo wrong.
    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.

    I am a little surprised to see no mention made of USB 3 connections being dropped when plugging a (supposedly) USB 3-capable external dock or enclosure into a motherboard port connected to a Renesas/NEC USB 3 controller. Speculation faults, for instance, the JMicron USB 3 controller on the dock/enclosure; ASMedia is speculated to be less problematic. At any rate, "real world" experience finds dropped connection problems, which makes speed a secondary concern. Can this "dropped USB 3 connection" issue be addressed as well? Thanks.

    USB3 on my Gigabyte board was very unstable, hard drives would frequently disconnect. Disabling USB3 Power Management helped somehow, but they still often didn't appear after boot. I tried all available driver versions to no avail. I'm running Windows 7x64, by the way. Also, the enclosures I tried wouldn't spin the drives down after the host PC was shut down. I finally got two eSATA enclosures instead.

    If SATA is set to AHCI it'll support hot-swapping if it's set to ATA/Legacy it will not.

    That is good to hear. I have used two different usb 3.0 controller and I don't notice difference on performance on mechanical HDD. Now that I know the performance is similar for different controller, I am thinking of getting SATA 3 external SSD.

    Is there a difference on USB 3/SATA adapters/enclosures? I have a WD Caviar Green 3.5" that the WD Elements USB 2 enclosure is bottlenecking (yeah, I know the newer ones are USB 3), and I'm wondering if the $15 Rosewill enclosure I'm looking at is good enough. Anything must beat the 25MB/sec I get currently though.

    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.

    There is High Speed version of USB2.0 which allows transferring of data significantly faster than the standard version. In my previous PC, it was enabled only on a certain port.

    I don't see a big jump in performance on my USB 3.0 vs my USB 2.0 in file transfer using a External USB 3.0 hard drive I go from 20mb on USB 2.0 to 60mb USB 3.0 on acg sometimes it will go up to 80mb but i notice if I'm transfering a bunch of diff files my USB 3.0 transfer speed drops to almost USB 2.0 speed.

    I have four external WD 3 Tb drives on USB 3.0, achieved with a four port hub plus a controller which plugs into the PCI 1x slot (motherboard does not have USB 3.0 native). I'm lucky if I can get 50 Mb/s sustained transfer from the internal HD to an external. It's about 2.5X as good as USB 2.0 sustained, but not too fantastic. Running Win7 Ult64 with 12Gb RAM and an i7-950.

    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.
