Will the 3.0 ports on this hub power external drives? Previous experience had a problem with this.

Do the external drives to be connected to the hub have their own power source? If they are intended to run off of the power of the hub, you may have problems. This is my speculation based on the note under the product description stating the product should not be used with WD passport hard drives. I have several of those, each 1TB, and they run off the power of the hub. Currently, they are plugged into USB 2.0 ports, but they are USB 3.0 compatible products used as "backwards compatible," and run very slowly with USB 2.0, but they run. With USB 3.0, there is evidently a reason they are not supposed to be used. So, I would say it depends on whether the external hard drives have their own power source and, specifically, if they are WD passport drives, the product information I saw said they should not be used with this hub.

I have two external drives, and there doesn't seem to be a problem thus far. I've only had this hub for one month, however.

Yes, I have a 320gb usb external hard drive operating off of this hub and it works fine for me.

I'm using Windows 7 Ultimate 64-bit with a 3.0 PCI add-on card connected to the 7 Port USB hub. I have a Seagate 2TB, 3TB and 4TB 3.0 drives attached as well as 320GB and 500GB USB 2.0 drives and have no problems. Just remember any USB 2.0 drive is still limited to 2.0 speeds. Some of the drives are network shares and still I have had no problems. The 7 Port USB Hub works great for me.

No they do not, I have tested it with mine. I am using a Sil3124 based PCI card with two esata ports to hook up my external drive enclosures.

I use a WD portable drive and it works well with this USB hub. (I did not try with more than one external drives.)

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

For me I found external hard disks worked, but I would get short term disconnects. I replaced my hub with a Anker hub and haven't looked back:https://www.amazon.com/gp/product/B00GSLMTQ8/ref=oh_aui_search_detailpage?ie=UTF8&psc;=1

I use a mixture of USB 2.0 and 3.0 devices. Everything I have connected to this hub worked as expected.

As this external SATA docking station is also a USB 3.0 hub, you should have no problem.

I tried to plug in an external 320GB hard drive and it didn't work at all. The enclosure had its own power supply and I have plugged it into other USB Hubs before, but this one didn't even recognize it. don't know if it was defective or a limitation of the design, but I am returning it considering that I bought this Hub to swap multiple external hard drives and thumb drives. Hope this helps.

I'm not sure about the amp numbers, but I'm using the hub with 2 USB3 portable drives, 1 USB2 Ethernet, USB keyboard/mouse, and USB/serial port, sometime plus more peripherals at the same time, without any problem.

Each USB output port can easily handle a USB 3 current load ( which is Greater than USB2 Current load. If your External Drive strictly operates from the USB3( or USB2) data cable that also carries power, it should be able to deliver and operate it. No harm will be done try it. ( Note many External large hard drives also require a separate external DC power connection. Check and refer to your Hard drive manual for it's specification and connections. Good Luck. BobNaz

This hub isn't for doing that. It's for adding USB slots when your computer's USB slots are filled. I have USB lines from two external drives, a printer, a mouse, and a cooling pad hooked up to my hub. You'll still need to plug your external drives power adaptors into a suge surpressor.

If you are using the power adapter that is supplied with the USB hub the hub then is independently powered and the external drives are more than likely being "tricked" into thinking that there is still an active connection between the drives and the PC, therefore the drives will not turn off with the PC. If you unplug the adapter the external drives should then shut down also. Will the drives being on damage the drives? Not really, because there is no actual activity (reading/writing) taking place when the PC is turned off. Does it use a little electricity? Yes, but it would be minimal. Bottom line, if you are concerned about the drives being left on, unplug the power to the hub and they should shut down. If it means anything, I have a PC that I built with 5 Western Digital Black Series 4tb hard drives in RAID 0 and a 2tb external WD My Book attached that run 24 hours a day, 7 days a week and they are fine.

It depends on how many drives you will use simultaneously. If it is only one or even two, you will have no problem powering them. However if you will use more than two drives, you should consider buying an externally powered USB hub.

12V 4A Power Adapter will provide a sufficient power for each port so you can run those external drives plugged into each port 24x7

Mine came with a power brick, for what it's worth. I believe that this hub corrupted my external usb 3.0 hdd, and pretty much killed it. Don't know this for a fact but I don't use it anymore.

I do not know. All that I've learned is that the drives and their external cases are very chipset-sensitive. Probably the case with the electronics is the more important factor. I'd try it, but return it if it won't work.
