    Regular consumer drives in RAID are accident waiting to happen Here is a quote from a review at pcper.comI’m going to let the cat out of the bag right here and now. Everyone’s home RAID is likely an accident waiting to happen. If you’re using regular consumer drives in a large array, there are some very simple (and likely) scenarios that can cause it to completely fail. I’m guilty of operating under this same false hope – I have an 8-drive array of 3TB WD Caviar Greens in a RAID-5. For those uninitiated, RAID-5 is where one drive worth of capacity is volunteered for use as parity data, which is distributed amongst all drives in the array. This trick allows for no data loss in the case where a single drive fails.

NAS/Server, I bought 5 WD Red drives from Adorama (purchased through Amazon) and 1 drive directly from Amazon.The one drive from Amazon came very well packaged, double boxed in what looks like a WD cardboard box with a shock absorbing cradle.
