1. Will this power (1) USB 3.0 Western Digital 2TB My Passport portable hard drive WITHOUT the power supply? 2. If so, will it run at USB 3.0 speeds?

Yes, runs at a full 3.0 speed and has enough power to run my Seagate Backup Plus ext hds
1846606
Yes, definitely -- I have it powering a couple of WD My Passport USB 3.0 drives, plus an external Blu-ray/DVD drive.

1. It seems to work fine unpowered, but I'm uncertain whether it's running at USB 3.0 speeds.

It seems clear that this unit does not come with a power supply, but seems to have a standard barrel connector to accept an optional power supply. To use small external (2.5") drives I need to have an external power supply. Can someone post a link to a power supply that will supply at least 2 amps and is compatible with this 4-port Sabrent hub?

This enclosure is powered from the FW800 connection. I don't presently have a USB3 interface on any of my computers but suspect it will work there, too. Additionally, I have a 5 volt, 2 Amp supply which came with a much older 2.5" external case that will fire up this drive. The outside ground terminal of the round 5V plug is roughly 1/8 inch in diameter, and that should let you find a suitable supply if you really need one. I have several FW400 and FW800 external drives in cases and rarely need this power supply. USB2 did not have enough power for a hard drive, and that may be why I have this supply. Does this help?

It depends on the enclosure. Some enclosures are capable of powering the drive with just the USB.

I don't know how it works in Singapore, but its adapter input accepts voltages from 100-240V ~ 50-60Hz (0.5A Max)I have only tried once and it didn't work with my two 3.0 WD Passport HDD connected at the same time... Otherwise, works well. I'll try it later

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.

Does the USB 2.0 port provide enough power for the external HDD? Or should I make sure to use an external HDD that has its own power source?

Hi. Thaïs product can power à USB hard disk drive 2,5 inch but not 3,5 inch because these one must be powered by external power. Sorry for my poor english. ;-)

This card will give you two USB 3.0 ports and close to the 3.0 USB speed. But it will not affect the speed of your e-sata port (unless it is being physically being replaced by this card.)My peraonall experience is that this card would not power my External USB HDD.

My understanding of the Surface Pro 3 is that it's being positioned as a legitimate laptop/ultrabook replacement. It's running the conventional x86_64 Windows code, and includes USB 3.0 ports. You have the entire package there to support this powered port. What's especially nice is the 4 amp power supply for this USB port. So, as long as you have 110V power to plug into, you'll have plenty of amperage to power external devices. Might be an issue when you're away from wall sockets.... especially if you're trying to run an external drive off the Surface's USB 3.0 port (and hence the tablet's battery) alone. But if you intend to use it only when wall current is available, (like at home or in a hotel room) no problem. I used it tonight to transfer a large amount of data between two external hard drives on the desktop setup I have (both USB 3.0 drives). It flew!

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.

As this is made for the Seagate FreeAgent GoFlex it has a cable with USB connections and an adapter to SATA. The Western Digital Passport has Mini USB, but the model called My Passports looks like it has the same flat USB 3.0 socket, so in that case you just need this.

Well I've never mounted this type of drive into and external enclosure but I'm fairly certain (about 85%) that you'll need more power than what a USB 2.0 can supply. Then again, I could be wrong.

I got a WD Passport 160 GB USB 2.0 Drive today. - It does not work on my 4-year old Compaq Presario 900 laptop (XP home with SP2). Nothing happens. - So far no trouble running it on my newer HP Pavilion dv4000 (XP home with SP2). With all the comments about working or not working with laptops I keep my fingers crossed! Noticed that reviews earlier this year were far more negative than more recent one's. Did they improve the product??

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.
