a cloud is not only a remote hard driver you can access anywhere. these days, all cloud service in the market offer sync function. remote access plus sync, that’s the cloud.
thus I would say WD is somewhat misleading in terms of my cloud. it does not come with a sync function. It is only a somewhat advanced remote hard driver. yes, installation of bt sync can make it happen. but then firmware 4.0 kill it. for me, the new firmware does improve performance a lot. previously, it is very slow to access the driver (even before I install bt sync, do not blame bt sync for it). now, it is much faster. Thus, I do not want to downgrade my firmware. However, I would like to see the official sync funcion from WD, or at least let us to DIY it. I am not a linux geek, but am forced into doing SSH.
please remeber, you cannot call you product “cloud” without the sync function.
