I want this to run 4 external hard drives that are self powered (usb powered) Will this hub work for that application?
2005291
I have two that are self powered with no problems. In my opinion it should support 4 external hard drives because it plugs into a power source.

The power supply that comes with it is rated at 2.5 amps, so I would say that if the total draw is less then 2.5 amps then you would be good. The max you are supposed to draw per port is 0.5 amps, so times 4 would be 2.0 amps. It'll probably work even if all four on at the same time.

It should because the plugable has it's own power supply you must plug into an electrical outlet.

MANUFACTURER ANSWER: Thank you for posting your question. External drives tend to be extremely power hungry because they have motors along with their electronic circuitry. They usually draw the maximum current that is allowed from a USB 2.0 port (500mA) or even more. Because of this, I would not recommend running four USB-powered external drives from this hub. It is designed for a typical mix of USB devices, such as a keyboard, mouse, flash drive, etc., including an external drive or two. The AC adapter for the hub supplies a maximum of 2.5 amps, so if the four external drives you mentioned each drew 500mA, then that alone would put the AC adapter near its capacity. Because external drives often draw more than the specified limit, especially when starting up, I would be concerned that a drive might disconnect suddenly due to lack of power during a write operation, possibly corrupting data on the disk. To be safe, I would recommend a maximum of three external drives if they were by themselves, or two if other devices are attached to the hub. For using more drives, I recommend our 7-port USB 2.0 hub with a 3.0 amp power supply (http://plugable.com/products/USB2-HUB-AG7) or one of our USB 3.0 hubs (which work on USB 2.0 ports), with 4.0 amp adapters. I hope this answers your question. David, Plugable Support

I believe the answer is "yes", although I have only had one external hard drive plugged in - as well as a printer, mouse, and keyboard.

The hub has a 12 volt, 2 amp power supply. I assume the amp capacity is divided among the 4 ports. You'd need to find out what the current draw is of the external drive to be sure.

I have not tried it with a powered hub, but would be very surprised if it did not work

I continuously run two 3GB external hard drives and occasionally plug in a third and never had any indication of a problem. Since this hub has an external power supply I doubt that you will have any problems. It is an exceptionally well-made hub.

Probably. I have six external hard drives, a dvd writer/player, an audio system, and I don't know how much more hooked up to it. I've never noticed a single problem with it, unlike every other USB Hub I've had, and there have many since I have so many external devices to hook up.

I use the USB switch with a powered hub. (The switch has no external power.) If you need a powered hub, I don't know. I changed to using a powered hub and have found the hub more reliable than a non-powered hub.

If your box appears as a single drive,maybe. be aware that this adapter will change the format of your drive and although you can still read it, it might not work in your situation. The manual not too clearly states that it doesn't work with USB hubs, and if your drive enclosure treats the two drives in that way, it won't work. Back everything up first, and be prepared to reformat your disks if it doesn't work.

Yes, that will work. The 2nd USB connector is just for power. That's because some older USB ports will detect a power overload if the drive tries to pull all its power from a single port. To workaround that they the Y cable can be used to pull power from 2 ports. Non-anceint USB ports, like 2.0 or 3.0 or from a powered hub will probably work fine if you just plug in the one end of the cable. Try it with just one. If it works, you're good. If it doesn't, the computer will tell you "power overload detected" and the drive won't work, but no damage will be done.

Not sure, depends on your source USB port. To be sure, I would purchase a "powered" USB hub to connect your drives.

I've used it for 9 DVD-Roms\Blueray drives just fine. You will have slowdown if they're all running at once, but I never had them drop like with other hubs.

This is a 36 Watt power supply, so yes, it should work with any of the "My Book Essential" external drives.But, note that this is not an OEM replacement part; it's an aftermarket item. Check the labeling on your drive-if it only needs a 18 Watt power supply, you can get an OEM power supply from the WD online store, if you care. If using an aftermarket power supply doesn't strike fear into your heart, this one should work.

This is a 9volt DC power supply, rated at 1.5 amps. As long as know that the power requirements of the external hard drive are less than 1.5 amps, it should work. You have to match the plug and polarity to use it. This is very important. Incidentally cable is 5 foot long.

Hi there Since I have the 4 port USB3.0 ...I have checked that my external hard drives that are powered up by an extension cord are USB2.0 and it works with my USB3.0 port on the USB HUB. I can not see why not it would not work with the 7 USB 3.0 port. I have this USB 3.0 port hub on Windows 7 Ultimate so it will work with windows 7.

I have 4 3tb enclosure plus 7 external drives .they work.i would think yurs should as well

I have a sort-of answer ---- I am not using additional drives on this HUB --- but, I am using one 2TB USB drive on another Anker HUB and it works fine. So, I am confident it will work --- I just have not tried it on this HUB. Also, this HUB is powered by the USB port whereas my other one has AC power --- so, that could play a role in how multiple disk drives perform.

Yes, that should not be an issue as there are USB ports available on the side of unit. If you need more USB ports I would recommend getting a USB hub that is self powered.
