If I plug 10 external USB drives in, e.g. 10 WD 2TB My Passport usb3.0 drives, will the performance be comparable to a single drive plugged in?

Whatever you plug 10 external USB drives or just a single , performance is always the best

I think it probably has something to so with the power consumption of the devices that you're connecting. If, for instance your connecting 5-7 hard drives chances are they're not going to all be recognized as they draw a great deal of power. While Ive not done it myself, Im thinking if you connected 7 USB thumb drives, that they would be recognized.

Should wrk. I only have two drives connected but they work just fine. I also use a external DVD player/recorder and printer. all have no problem working. Good luck.

You have two internal hard drives? Not many computers have that. It wouldn't be possible to say which is the quickest without knowing the transfer speeds of both drives. It may not be a significant difference anyways. The edge the external drive would have is that you can easily and quickly remove it and connect it to another computer if something catastrophic happened to your computer. Another thing- as far as I can tell there was no backup software included for the Passport so you'll need to rely on your computer's backup software. That's probably not a factor. In the end it's probably apples and oranges whether you go with an internal or external drive. Personally, I prefer the portability of an external drive. Good luck with your purchase.

It depends on your computer and the drives enclosures attached. Only a small set of USB enclosures operate at full USB 3.0 speeds. And USB still requires the computer to manage arbitration of disk IO, which could become overwhelming if you are attempting to move files to multiple drives in parallel. In short, you should try it. But in general, if you need high & predictable IO transfer rates with low latency, such as for OLTP database IO, USB is not your best choice. If you want low-cost bulk IO, USB might be fine.

Yes, it works fine in USB 2.0 ports, usually faster than a 2.0 flash drive in the same port. You won't get the screaming speeds of a 3.0 flash drive in a 3.0 port, but it's definitely an improvement over the 2.0 flash drive.

sorry, I haven`t tested that. I will have a USB3 portable hd soon. I'll check it out.

Tested with a WD Passport USB 3.0 2TB 2.5" drive. It seems to power it, though it turned off after 6 or 8 seconds the first time. After powering off, it came back on, my device said it detected mass USB storage, but there are no new mount points created, probably because the drive is formatted in NTFS and not exFAT or whatever it needs to be.

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.

Don't know. All this thing does is provide the power of two USB ports rather than one USB port to the same device. Is that adequate? The size of the drive should not matter, whether 500 GB, 1 or 2 TB--it is just surface area; RPM may be a factor. since more power maybe required to spin faster. I got mine for the 7,200 RPM drives--recommended for such--but ended up not using it and using the external power adapter instead. I have not used my Y-splitter to date--should return or resell it. WD also makes an external power adapter for its drives--I have one for its backup drive. The Apricorn external power adapter is $10, cheaper than this. Idea is this may be more flexible.

I use the hub with multiple WD external drives which have USB 3 connectors. If the Ultra 2TB drive has a USB 3 connection, then it will work. I checked the Amazon listings for details and the WD _My_ Passport drives (regardless of size) all have USB 3 interfaces. That means they will work with this hub.Note, to take fullest advantage of the USB 3 speed, you will need to plug the hub into an USB 3 port on your computer. Otherwise, the speed will be that of the port.

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.

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 got 60+ Mb/sec when transferring huge files to the WD Passport 2Tb drive with USB 3.0

Unless there is a secret I am not aware of, you can only have 26 drives in most windows systems. Not sure about Mac. None the less, one of those drives would need to be your OS as well leaving you with 25. Not everything one plugs into USB is a drive to take up a letter. I dont think that was the intention of having 28 ports. :) So to answer your question, I think the most you could copy is 25 at one time. You could do that using GoodSync.

I believe the Western Digital Passport series qualifies for the 7200 rpm speed but this USB powered drive is powered from the USB port with no means to power it with an external power source. If you must have an externally powered drive you might consider purchasing a external hard drive enclosure that supports that feature and a bare drive with compatible specs and then assemble them yourself.

I don't know about SuperDrive but I have two WD passports (500 each) plus My Bookconnected through 3.0 7-Port Hub without any smallest trouble.
