        Bought two of these drives to place in a new Synology NAS and have not been disappointed. The read/write times have been plenty fast and I have not noticed any considerable noise from them either. I would highly recommend the drives. Hopefully they will keep dropping in price.

            I use these drives in a Synology DiskStation. I'm up to 4 WD40EFRX. I know the 6TBs are coming but I couldn't wait. Also, I want to see some reliability reports on those before making the move. Anyway, for $/each, I couldn't really ask for anything more.

                Comments about 4TB Network HDD Retail Kit (WD40EFRX, Red Drive):

                On its own, the WD40EFRX is really a great NAS drive. I purchased this to replace a 5 year old 2 TB drive that wasn't a NAS-specific drive. So far it runs well and the replacement process was easy since my QNAP has hot swap capability. The 2 drive-kit is a better value especially since I have a 4 drive QNAP. I haven't replaced all of my drives but plan to do in the near future by purchasing more WD40EFRX. Why buy from B and H? Packaging. Would you risk equipments that will be in constant use for the next 5 years to shops that ship them unprotected? Mine came a in heavy box with plenty of padding, in addition to these were in their own retail individual box, not just shrink-wrapped. Thank you B and H!

                  Been running 2 4TB WD Red drives in a Synology NAS Hybrid RAID for a couple of weeks with no issues so far. Bought these for their reputation for reliability, and they have not let me down. Only time will tell wether they are truly reliable, but I have had other drives fail rather quickly, so recommend that you stick with Red drives for server application.

                                  I poured over articles and reviews researching what HDD is best suited to run in my SYNOLOGY NAS, and when factoring cost; reliability; features (particularly error correction controls); and capacity, this HDD is the best available IMHO.
