Perhaps somebody will be interested...
The CHARGER Doctor was used to measure the current in the following cases. The Note 3 maximum continuous output current is somewhere around 900mA.
Most portable HDDs consume less than 1.0A, therefore, the Note 3 will power most portable HDDs.
Unfortunately, the Note 3 is unable to properly power the new Seagate Backup Plus Fast 4TB portable HDD. The drive operates fine with the Note 3 when supplementary is provided.
The maximum current drawn (benchmarked with A1 SD Bench on Note 3) by the Seagate drive was 1.39A (provided by the Note 3 charger itself.) At idle, the Seagate drive consumed about 500mA.
If a high capacity HDD drive is needed with the Note 3, it is advised to go with a drive which consumes less current.
If using the Seagate drive with an Intel USB 3.0 port on a computer, then I saw currents as high as 1.33A. The same computer port was able to provide about 1.16A continuous.
It would seem that the Seagate drive requires continuous current of greater that 900mA, considering that the Note 3 has been shown to output 900mA continuous and is unable to power the Seagate drive.
P.S. I don't believe it is possible to enable USB 3.0 transfer speeds with a HDD on the Note 3. The only way to enable USB 3.0 speeds on the Note 3 is when the Note 3 is connected to a computer, AFAIK.
