It has being reported that the Spotify client software on both the Mac and PC platforms is deliriously writing data at the rate of several GB's an hour. Rather paradoxically, it is not filling the volume with data, but the high writes and reads will severely shorten the lifespan of a SSD volume (and mechanical storage). Users have confirmed that this process is happening with the client whether it is playing music or not. Most disturbing, this damaging process will be invisible to the majority of users.
