Can it be bus-powered via thunderbolt or USB3 or do you have to have AC to power?

It uses an external power supply. It only used the USB and thunderbolt connections for data transfer.

You have to have AC to power it. The smaller, "min" versions of the g-tech drives are able to be bus powered. Strangely, on the amazon pages per the technical details, in the "Special Features" section, it says "usb powered". However, upon looking at the g-tech web site and other resources, this likely just refers to it having usb ports...more of a marketing term than a technical term. I reviewed the technical manual, product guide and datasheet on the site for the product with no mention of being able to use the USB to power it. I will try with mine at home but I have had mine for a little over 6 months and had it AC powered the whole time. I would not expect a workhorse like that to be able to be bus powered.

Thunderbolt transfers data at 10 Gbps. USB 3 can only manage 5 Gbps and USB 2 will max out at a very slow 400 MBps.

Right. This is a powered hub that is only connected to the MBP or what ever other computer via thunderbolt. It doesn't send power for eh computer itself. Some USB devices such as the SuperDrive and some hard drives are not able to get enough power from the hub, and must be plugged in directly to the MBP.. Overall though I am thankful for this hub and it works very well.

If you want only usb cable, yes. It is not AC powered, though. I use one to supplement an AC powered 4-port USB hub.

Depending on what you put inside it, you might need USB 3.0USB 3.0 can supply much more power than USB 3.0And now there is even USB 3.1

The only problems that people have had with the apple adapter is with bus powered firewire 400 & 800 devices, due to the fact that thunderbolt supplies something like 7 watts while firewire can be in the 20-45 watt range depending on the hosting device. But since this drive is powered off of a external source you will not have that issue. you should have no problem running this drive from a thunderbolt adapter.

There is a AC Adapter included, and since this is built for a 3.5 drive, will require a power adapter, though the nice thing is that it's included.

No, I draws its power from the mother board. You may be thinking of USB hubs, which often require external power. Hope this helps.

The drive as it is , is a USB3 . To have it Thunderbolt capable you would need to buy the optional Thunderbolt adapter. Would the Thunderbolt adapter workd on the 1 TB drive ?. I dont know

The hub will NOT work with out power. I tried it out with one USB drive and it will not read the drive until AC is added to the unit.

NO! It is a powered hub. Having said that, I love these puppies. I've got 5 total in use and highly recommend them. (See my earlier review.) on USB 3 items, they'll draw power from their own power supplies and the computer itself, you DON'T ever want to take a chance of burning out the USB on your puter or the device (Like hard-drives) due to a low power situation, EVER!The plugable 7 port hub is lighted to let you know when the device is properly connected and powered, on each port.

The hub itself can use an ac adapter (not included) however it is not required from my experience. But, if your external drives use an external power such as a ac adapter then yes you would still need the power for those drives but not for the usb 3.0 hub itself. You would only need to power the hub itself for power hungry applications. I currently have a WD Ultra Passport external drive (which requires no external power) and two external disc drives attached to mine (one lightscribe dvd writer, and one asus bluray writer drive) each of which is powered seperatly by ac cord. My 4 port Sabrent USB 3.0 Hub has no power to it other than the computers bus power. I hope this helps. Cheers!

Hi David, thanks for your interest in our products. Yes, our monitors require AC power for several reasons. The first is our products all have two spare (powered) USB ports for other USB devices, and these ports require AC power. Next, our monitors also have HDMI input and this also requires AC power. Finally, our latest product, Monitor2Go FHD has speakers (for use with HDMI) which requires AC power too. I hope this is helpful. Please let us know if you have any other questions and feel free to email us directly at contact@mmt2.com. Thanks!

It should only need bus power. I have used this drive as last in chain to a powered desktop drive (FW800) then into a MacBook Pro without using an external power supply on the G-Tech drive.

This unit does not have a thunderbolt port. The MacBooks do not have a thunderbolt port. Only the MacBook Air and MacBook Pro may come with a thunderbolt port.

It will power a portable USB Hard drive. I run this configuration in hotels, where I can power the MacAlly simultaneously through its separate miniUSB charging port. While it can run a drive purely off its internal battery, but don't expect much in battery duration.
