Just a quick update. I got the Filehub plus in yesterday. I hooked an external drive up to it and transferred 6.4GB of photos (raw and jpg) from an SD card to the external hard drive....it took 20 minutes to complete the transfer. This is after connecting to the hubs Wifi, opening the app, waiting for it to read the attached storage (SD and USB), selecting all the files from the SD card, and choosing to copy them to the external HDD. So another few minutes to set up the transfer. That same 6.4GB took 1 minute to import into Lightroom from both the SD card and the external drive. I then took 10 more photos on the same card and did tested just selecting all photos on the card (including the ones that where already on the HDD) to test how it would treat duplicate files. It stated the transfer and easily, but slowly, transferred the new files then the app asked if I wanted to overwrite the duplicate files. I clicked no and the app said the transfer failed. Checking the HDD all the files that should have been on it were there so the transfer did work. In the end the file hub plus is not a great option to back up in the field. Is it useable? Yes, but so very slow
So being unhappy with the Filehub plus I broke down and got a WD My Passport Wireless Pro today. The difference between it and the Filehub plus are huge. Using the app I set the WD to automatically import when the SD card is inserted and there is an option to only back up new files. Once I was done setting up the drive (only has to be done once) I tested out the transfer speed using the same card I tested the filehub with (which still had the extra files on it so it was now at 7GB instead go 6.4GB). After inserting the card the drive began the transfer a coupe seconds late and was done in under 2 minutes. I took 10 more photos and put the card into the WD drive. It stated the transfer but took about a minute to transfer the new files. So seems like its slower to do incremental transfer then to just dump a while card at one. Also it creates new folder on the drive for each import. So the new files were in a different folder then the first import. That is one down side to it compared to the Filehub. On the file hub and can make folders and trandsfer files to what ever folder you want.
Still the WD is WAY faster then the filehub, is just plug and play in that it doesn't require me to use an App to find, copy, and transfer the files, and can do incremental transfers.
Also one that I was pleasantly surprised about with the WD was that the My cloud app WILL render previews for RAW files. I had read that it would not but when I connected to the drive there were previews of the raw and jpg files. Im not sure if its because I was shooting raw+jpg that it had previews so I'll have to do more testing on that. If it doesn't need a jpg file for the preview then all the better as I normally don't shoot raw+jpg.
Once last thing, I am a Lightroom using so I have Lightroom mobile on my phone as well as Snapseed. Both the Filehub and the WD will allow you to open (copy) files in either program on your mobile device.
So the Filehub is going back and I'm keeping the WD. It's not perfect but it does what I need and is a much faster option
