You might have seen a company on Facebook or on the web called Connected Data offering a product call a Transporter or Transporter Sync. The products allow you to setup your own private cloud service, Great idea right goodbye dropbox, iCloud, one drive, copy, etc. so I purchased a sync ( it allows you provide your own usb hard drive for storage). It takes an hour or two setup and get working, To access your drive you will need a helper app ( they have the app for MAC OS and Windows) they also have apps for iOS and Android mobile devices. As well as a free account on contacted data site so you can claim your transporter device, The transporter works as advertised wight he following warnings IT DOES NOT SUPPORT SSD DRIVES, or DRIVE OVER 4 TB, you MUST PLUG IT INTO a !Gig ETHERNET port. the USB port is on 2.0 yet the recommend that you use a USB 3.0 drive. Copying of files is REALLY SLOW on both wired and wireless ethernet connections. It reformats your usb drive and wipes out all of your data. If you need to upgrade your external hard disk you must copy all of the data off of your existing transporter drive to another disk. Replace the existing drive with a new drive wait for it to reformat the new drive.. Then you can copy your old files to the new drive, and as I have stated that is a SLOW PROCESS!. Another oddity is that it does not like long file names (I found this on PDF files I use for work) I opened a ticket with support on this one to find out sorry it does not do that. File sharing is kind of different too, you have to create an email request to add people to the file or folder, in turn they have to sign up for a free account to gain access to what you are sharing. You can add other Transporter into your private cloud, they will replicate data to and from each other.
It is a cool device but it will chew up your bandwidth since it passes data over your internet connection.
I have to give the Transporter 2 out of 5 stars for now.
They just released an update to the helper apps. I will test them and see what is fixed. UPDATE: The new helper apps seem to be a bit faster in loading, updating the Transporter and Transporter Sync folders. So that is good. Now 2.5 out of 5 stars for now.
