Our Review

The Western Digital WD40EFZX WD Red Plus 4TB SATA 6Gb/s HDD is a strong contender for anyone looking to enhance their NAS setup, priced at £188.94, which is the all-time lowest recorded price. With an impressive rating of 4.3 out of 5 from 2,736 reviews, this hard drive is designed specifically for NAS environments, making it an excellent option for both home users and small businesses.

Key Features in Detail

The WD Red Plus drive can handle up to 112TB of storage in an 8-bay NAS system, which is perfect for archiving and sharing digital content. The NASware 3.0 technology optimises the drive for NAS use, ensuring seamless integration and performance. This drive is also equipped with dual-plane balance control technology for improved reliability and performance, making it suitable for RAID configurations often used in ZFS or other file systems.

Performance Assessment

In terms of performance, the 5400 RPM speed with SATA 6Gb/s ensures decent read/write speeds, appropriate for standard NAS applications. While it doesn't compete with SSD speeds, it's more than adequate for streaming, backing up, and sharing data across multiple devices. Users have reported smooth performance even under heavy workloads, which is essential for tasks like RAID array rebuilding. However, its lower RPM compared to competitors like the Seagate IronWolf 10TB may lead to slower speeds in high-demand scenarios.

Build Quality

The WD Red Plus is built to outlast standard desktop drives, as it is specifically constructed for NAS usage. It is rated for 24/7 operation, which indicates that it can handle constant use without significant wear and tear. The construction quality reflects WD's commitment to reliability in storage solutions, but it is important to note that it may not be as robust as the WD Red Pro series, which is aimed at larger businesses.

Value for Money

At £188.94, the WD Red Plus offers good value for a NAS-optimised hard drive, particularly as the current price is the lowest ever recorded. However, when compared to the Seagate IronWolf 10TB at £339.19, the WD Red Plus is a more economical option, albeit with less storage capacity. The average price of £188.94 indicates that this is a fair deal, especially for customers who require reliable performance without breaking the bank.

How It Compares to Alternatives

When compared to alternatives like the Seagate IronWolf, which offers a higher storage capacity of 10TB for £339.19 but at a higher price point, the WD Red Plus is suitable for users with moderate storage needs. For those requiring more extensive storage, the IronWolf might be a better fit despite the price difference.

Genuine Negatives

One potential downside to the WD Red Plus is its 5400 RPM speed, which may not suffice for users with demanding applications such as 4K video editing or extensive virtual machine usage. Additionally, while the drive is designed for NAS environments, some users have reported compatibility issues with certain NAS models, which can be a concern for those investing in a new setup.

Conclusion

The WD Red Plus 4TB SATA HDD is a reliable choice for home users and small businesses looking to create a robust NAS setup. With its focus on performance and durability, it caters well to the needs of archiving and file sharing. It is best suited for those who do not require massive storage capacity but still want dependable and efficient operation.
