Will it run 10 external hard drives, each of which has its own power supply?
2082981
I can't answer your question from personal experience as I don't have 10 USB 2.0 hard drives.But at the moment there are 5 USB 2.0 hard drives running off my Satechi including one that does not have an external power supply. In addition my keyboard and mouse, a DVD drive with no external power supply, an Epson scanner, and an HP laser printer are connected to it. I see no reason why there couldn't be even 12 hard drives connected if each has its own power supply, provided the Satechi hub is being powered by its ac adapter.

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.

In this moment I have 4 external hard drives with their own PS, a thumb drive, printer, El Gato EyeTv hybrid tuner, the scanner, mouse, and a usb extension cord for easy access. I don't own 10 drives, but so far it's performing great.

As long as you plug it into the wall with the adapter, there shouldn't be any problem. I run 3 off of mine, as well as a keyboard, mouse, ex.

I don't think this hub is built to deliver that kind of power. All my external USB hard drives are separately plugged into the A/C. At minimum, your drive would probably have to be plugged into multiple USB ports.

Yeah, it has the power cables for power gaming video cards. I use mine to power 3 video cards and 9 drives (HDDs, SSDs, DVD drives). Without looking anything up I'm pretty sure it's capable of powering 4 video cards in addition to about 10 drives.

Yes, if you get a 5VDC power supply with the appropriate plug, it will allow you to supply the requisite power to the unit separate from the data connection. Some drives require more power than others, and some devices don't supply enough, as in your case, so this solves that problem.

MANUFACTURER ANSWER: Thanks for asking! You can connect two self powered external hard drives to this hub. This hub will not be able to power two host powered external hard drives. USB 2.0 has limited performance overall, however, you should not see any noticeable drop when comparing this hub to using several USB 2.0 ports directly on your computer.

Yes, The power supply comes with 10 SATA power connectors spread across three modular cables.

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

Good morning. Yes the power supply you have mentioned will work just fine. Anything over 650w will work. You might want to consider a higher wattage if you are using more than two hard drives in the case.

I have the 2 bay case and the power supply handles both drives all the time. There is no selective power options either, it powers all drives in the case.

Your power supply needs to have enough power for every component in your system. If that is the case then each drive will have sufficient power. Each drive will still appear to be a separate drive unless you configure the drives as a raid; this cable simply provides power to the drive. You will also need a SATA cable to connect the drive to the controller.

As many as you want given your power supply can supply the power. I have wired over 10 together with no problem in referents and such

All I know is this. It is non-powered hub. Works for multiple flash drives *as many as three have worked at the same time for me*, but if you try external hard drives you will run into difficulty because there is insufficient power from a single USB port to run multiple devices that need more power. t

1, yes. if you power a HD of the 5V USB, it will run at about 5200RPM like a laptop HD. This will slow down your transfer rate. 2. I don't believe this should slow down other USB devices more than normal. Only one device can be accessed at a time anyway,but It all happens so fast you wont notice. 3. Depending on Seagate, normally the enclosure should see it has 12V and not need any power from the USB. Unless your are hanging 40 USB devices off your PC, there should be no power issues with other devices.

It should work just fine. The voltage on most Hard Drives is always 12vdc. The amperage is key as it looks like this power supply is rated to handle at least 3amps just fine. Looks like a good buy. Clem

hi, yes it will, just as long as that portable drive doesn't require it's own power source. if your drive came with a power adapter, chances are you'll have to plug it into it's own source.

depends on other hardware, graphics card, number of harddrives etc. google "psu calculator" and compute your power needs

Yes it will work. I'm using it in this configuration with 2 Seagate 6TB drive. Seems like you will have full speed up to 4 drives then half of it up to 8 drives.
