I purchased the very first one of these Ext HDDs, a Transcend 4TB model, over a year ago, and it still functions virtually perfectly, with the exception of the fact that there was a period of time during which it could not connect via USB3.0; nevertheless, despite this, it was still viewable via USB 2.0 without any issues. However, problems were not found at that time on any other computers that had this device installed. At this very moment, there is no longer any trace of the issue at all. The operation has never been interrupted by a hangup or a bug. After that, a couple of months ago, I decided to take a chance and buy a second one because the first one has been around for more than a year and, in general, there aren't any issues with it.
