the same rumour tends to surface whenever new drives go up a size.
my advice is wait for the revised models, as usually revised models come out after a while which will likely have fixed any problems that may have existed in earlier versions.
currently I do have 2 3tb wd red drives.
they have a 700gig partition on each which is software mirrored in windows, that has valuable important data on it hence the mirroring.
but I didnt want to mirror the entire drive's as is a lot of space to lose, so the other 2tb or so space is seperate partitions used for downloaded media, encoded video clips I make etc. Whilst it will be annoying if I lose any of that data, it isnt as critical as what I have mirrored.
the wd red models are rated higher for average meantime between failures than blue/green/black drives as well.
