If I had two, could I power 1st w/ USB, and then daisy chain the 2nd w/ Esata, and use the external power supply? That would not tie up two USB ports?

You could use two like that but it would not be daisy chaining. There would be no connection from the first drive to the second, but the computer would see both.

Daisy chaining using eSATA is not possible.Also there is this misconception than eSATA rated at 6 GB/s is faster than USB 3.0 rated at 5GB/s, but it doesn't work that way. In practice, your USB 3.0 will have read/write speeds of 400 MB/s while the eSATA will get 350 MB/s.

No. The eSata port on the MiniPro cannot be daisy chained but must be connected to an eSata port on the computer. If this is a desktop you may have the ability to buy and add an internal eSata card to give you a number of externally available eSata ports. My laptop has an eSata port. It is eSata 2 however and is not as fast as eSata 3. It is faster than the USB 2 ports on the laptop. With the desktop I use a USB 3 hub (running out of power strip outlets).

No. Each port requires an interrupt to the microprocessor (CPU). Daisy chaining would confuse the system so CPU would not know which device it was dealing with. So that will not work. What you need is a USB hub. That will power both USB drives and act as an intermediate processor which the CPU can deal with. USB hubs are rather inexpensive. USB, however, will be considerably slower than eSata. But it is more convenient.

Mine has 2x eSATA on the back (below the USB connectors).The QNAP information page states this as well (http://www.qnap.com/useng/index.php?lang=en-us&sn;=862&c;=355&sc;=526&t;=690&n;=9906&g;=1).Hope this helps :-)

Don't have exactly such an experience, but this is one among not many (if not the only!) capable to connect multi-drive bays with spawned (e)SATA. Have connected self-made 5 drives bay, worked fine.However, i would advice you to ask Drobo's tech support regarding tech specs requirement and if their boxes either provide multi-drive (spawned SATA), or single logical RAID-drive on eSATA port.

Yes. 2 USB at the same time and in addition another AC plug. All will power simultaneously.

I have a brand new laptop with an esata port. This enclosure does recognize my external drive via the USB connection, but won't recognize by esata cable. I followed the instructions to use the USB cable for power, and even tried plugging in to a second USB port as suggested, in case one port wasn't supplying enough power.I'm trying to get through to their online support page, but so far no luck. So I'm up in the air for now.

StarTech just clarified it will work only for eSata port on external device and USB 3.0 on PC, not the other way round

I think probably not. I think the eSATA cable is only for data. My own setup has a second plug to draw power from the USB 3.0 port for the drive.Hmmm, the Wikipedia entry says that eSATA cannot supply power..."However, eSATA connectors cannot supply power, and require a power supply for the external device. The related eSATAp (but mechanically incompatible, sometimes called eSATA/USB) connector adds power to an external SATA connection, so that an additional power supply is not needed."

With the USB connection it will see both drives. If you use eSATA, you can see only one.

One drive-likely no problem. You could try attaching 2 drives and might be fine, I am not sure. Again, to be safe, buy a "powered"hub.

No additional power to the card is needed as both esata and sata drives have separate power connectors. This is not a USB card.

I have not tested these for daisy-chaining them, but with other simular (these are better built) I have done 2. I personally do not go beyond that. If you need to go longer, I would consider USB over Cat5 adapters (not internet.. the adapters just use Cat5 cable) OR better yet.. Move the equipment in question.

Actually, it did not work for my purpose. My PC fried and I tried to restore files to a new box (USB 3.0 interfaces) from an eSATA external drive. Did not even register. FYI: I then tried a "Newertech" eSATA to USB 3 connector pod (pn NWTADESATA6USB3 -- Barcode: 1309000527) from "Otherworld computing". It worked. I wish you luck

i plug in a couple of external drives w/out power source all the time. works just fine. don't know if it'll power more than 2.

The 2 usb is there to simply give more power. Mine ran perfectly fine with 1 usb. But if it doesnt just plug 2 usb in for more power
1136677
Yes, you can connect two of them, it should not matter but I would not run both at the same time.

Mine only has one USB port. Power and data are through a single USB cable. Sounds like you would be better off with a unit that comes with an external power supply. More of an opinion than a proven fact. Good luck.

Yes, it does require two ESATA ports. However, it comes with a PCIe RAID card which is installed in the server, so you're lack of ESATA ports isn't an issue.
