According to our internal hard drive HDD expert
The WD Red Plus WD40EFZX 4TB is optimized for NAS systems and is suitable for home users as well as small or medium-sized companies. Expand your NAS with this 3.5-inch hard drive and you can share your files with your devices at home or at the office in multiple RAID applications. You could use the Red Plus as a backup drive, something the base models aren't suitable for. With 4TB, you'll have enough storage capacity for 400 Full HD movies of 2 hours or 400,000 photos. Thanks to the built-in anti-vibration sensors, the drive will last longer than a regular hard drive. With a rotation speed of 5400RPM, this drive is energy-efficient, too. When you're not processing any files, the WD40EFZX lifts the read-write head from the disk. That way, it doesn't wear as fast, which makes the drive more durable.

Great drive for a NAS system. Due to low energy consumption and limited noise production, it is recommended for systems that are on 24/7. The speed of 5400rpm is more than sufficient for this purpose (higher disk speed means more power consumption, more heat and noise, but makes little sense for a home NAS). Can't say much about the reliability (using 4 units in a Synology NAS for a few weeks), but because of previous good experiences with WD I have confidence in the lifespan.
