Bests & Worsts Reviews from Amazon

I have purchased a lot of these WD purple hard drives over the years to record video from our cameras. Up until recently I have always had good luck with these and they have been solid, however in the past few months, I have had three failures on drives that were less than a year old. WD did replace them, so I am happy about that, but I am a little concerned that the quality has gone down. I hope it was a fluke… Update - another failure. Tried to open a support case with WD about this and it has been over a week with no reply. Changing my rating to two stars.
