In this blog, we’ll dive deep into the specifications, features, performance benchmarks, and ideal use cases for the WD40EZRX (also known as WD 4TB) and help you understand if it's still worth buying today.
The WD40EZRX is part of WD's Blue family of SATA hard drives, designed for everyday computing. It offers 4TB of storage, making it ideal for users who need ample space for files, applications, media libraries, and even games.
Model: WD40EZRX
Capacity: 4 Terabytes (4000GB)
Interface: SATA 6Gb/s
RPM: 5400 RPM

This drive is not an SSD, so it’s slower compared to modern solid-state drives, but it delivers excellent value for archival and bulk storage purposes.
With 4TB capacity, this hard drive is perfect for storing movies, documents, games, backups, and more. Whether you're a content creator or a home user with heavy storage needs, this HDD offers plenty of room.
Thanks to IntelliPower technology and WD’s engineering, this drive runs quietly and stays cool, even under load. That’s a big plus if your PC is placed in a shared workspace or living room.
The WD40EZRX is energy-efficient, making it a great choice for home servers, NAS setups, and systems that run 24/7.
This technology ensures the recording head never touches the disk surface, reducing wear and increasing the drive’s long-term reliability.
Here’s what you can expect in terms of performance:
Read Speed: 120-150 MB/s (Sequential)
Write Speed: 115-140 MB/s (Sequential)
Random Access: As expected for a 5400 RPM drive, random access is slower compared to SSDs.
While it won’t break any speed records, it performs consistently for daily tasks such as file backups, video storage, and light editing workflows.
Perfect for users with large movie collections or personal video libraries. You can store thousands of HD or 4K videos and stream them locally.
If your office needs to store Excel sheets, Word files, PDFs, and system backups, the WD Blue 4TB drive can handle it with ease.
Install it alongside an SSD to store large files while using the SSD for your operating system and apps.
While not a dedicated NAS drive, many people successfully use the WD40EZRX in basic NAS environments for home use or small businesses.
WD Blue (like WD40EZRX): Balanced performance and price. Ideal for general use.
WD Black: High-performance drives for gaming and video editing.
WD Red: Designed specifically for NAS setups with higher durability and a longer warranty.
So, if you're not building a server or high-performance system, WD Blue is the most budget-friendly and practical choice.
Even though this model has been around for years, it’s still a smart choice if:
You want large storage at a low cost.
You’re okay with slower speeds in exchange for reliability and quiet operation.
You’re setting up a backup system, media server, or office file archive.
However, if speed is a top priority (e.g., for video editing or gaming), you may want to look into SSDs or 7200 RPM HDDs.
Use it as secondary storage with your SSD.
Defragment it regularly to maintain performance (HDD only).
Keep it in a cool, dust-free environment to extend lifespan.
Always backup important data, even on reliable drives.
