WD - Red Plus 4TB Internal SATA NAS Hard Drive

I ordered two of these in 4TB capacity to use in my Synology DS220j NAS. No problems getting them formatted and set up in the Synology Hybrid Raid (SHR). So far these seem to run cool and fast. When copying data I was hitting the 1 gigabit transfer limit of my local network. Will update if anything changes.

Let me start by saying that this drive is a great value when considering the capacity for the price per Gigabyte. If my math is correct it is about $0.03 per GB of storage. The WD Red series have great capacity for the Network storage niche. I have been using Western Digital drives to store my important files and information for over 10 years now. I have yet to have a drive fail on me from WD. I still have all my older drives. The only thing that changes is capacity. Western Digital's warranty is great too!

This NAS drive has been pretty reliable, but they seem to fail once the warranty expires after three years. This model has been replaced by an newer Red drive, the WD40EFAX which uses SMR technology, this drive uses CMR technology. While WD does not state it, you CANNOT mix CMR and SMR in a drive array as it will cause errors. The SMR drive also takes a lot longer to rebuild in an array. Unfortunately, if you want to buy a CMR drive you will now to buy the Red Pro line of NAS Drives.

Love these hard drives. I added this one to my current array for 4 drives total. The other 3 drives have been running rock solid for the past 4 years with zero issues. Drives are healthy perform well.

I recently purchased a NAS by Synology, the DS415+. I researched HDD drives and found the Red series by Western Digital to be exactly what I needed: fast read/write speeds, reliable, and good value. I saw the same drives on another website at a lower cost. However, BestBuy offered me a price match, and I also opted to have them ship my drives to the local store so I wouldn't have to wait for shipping. Quick and painless; good deal!

Purchased this drive to use on NAS, received the product on time. Opened it and inserted to the NAS and it's working great no issues at all.

I trusted Western Digital brand based on my experience. Hard drives actually do last but all will eventually fail after a few years so we need backups of course. Some fail sooner, some fail longer than the manufacturer's expected lifetime. This is the first time I'm getting the hard drive designed for NAS type. I hope this lasts longer than a standard hard drive.

I was skeptical of paying so much for such little storage because I always hate when a typically reasonably priced item is branded "x". As such all the reviews I have read said that you should buy NAS branded drives for their speed, efficiency, and reliability. So I did, and so far I am not disappointed. My initial setup is not in a RAID configuration because right now I just need the space, however I plan to add an additional 16GB and place that in a RAID 5 configuration.
