great drives, great packaging

I love WD's higher end drives like the Blacks, Reds, and Purples (Greens and Blues are garbage). I pretty much use WD exclusively, except for SSD which I prefer Samsung Evo's . I have 2 Synology NAS' with WD Reds in Raid 5 arrays (4 drives each). one drive starts to die approximately every 3 years (IO errors with a few bad sectors). I just configured a new Synology RS820+ in raid 10 w/(4) 4tb WD Red pro drives. No problems at all. The drives were shipped in OEM boxes, within a bigger box. All nice and tidy. I then ordered another drive, as a spare, which was also nicely packaged. I went with red pro over regular red for the higher cache.

Works as described... add one step first.

Works in the NAS as it should but you have to do one step before you can add it to the RAID. You need to remove all other HDD to format it, in the WD My Cloud EX4100, unless you have a stand alone setup to do so. Once formatted, you're just a few button clicks away from getting it setup on you RAID. Our last HDD was the same brand and size that lasted about 7 years at a usage rate of nearly 50 hours a week.

So far so good

Only time will tell, but these appear to be doing the job. I use them inside my Thunderbay 8 enclosure. I'm getting about 600MB/s write and 1500MB/s read with RAID 5. I bought the drives with the intention of letting them run pretty much constantly. I don't want to have to replace them for at least five years. We'll see, but so far so good.
