The WD My Book works after 3 months still properly. With one Eischränkung: Once she has "hung up" but what could be solved by short disconnection from the mains. The recordings were not lost. Nevertheless, a star less.
The hard disk runs very quietly. The flickering Singnallampe you should cover, if necessary, if they bother because.
It is also important, it runs only when needed to.
But why so big? To my knowledge, all PVR recordings are encrypted DRM. Recordings can only be given to the TV unit back, from which they were taken. In exchange of the TV device, the hard drive must be reformatted. Therefore not suitable for a noteworthy film archive. 500GB or less would in my opinion be enough.
