I have a total of 4 WD Red NAS 1TB bought for two stations, 2 on Amazon, 2 through another dealer to have a scatter in the series. The plates on Amazon run without problems, the other two are defective on the first day. The first plate was out of the box out a head crash, the second panel, the review by the NAS did not survive and was reported as defective. Not exactly an exhilarating rate.
