Overview

Western Digital's WD Blue series has long been a go-to brand for internal hard drives designed for desktop PCs. The WD20EZBX-AJP model we're looking at today is a 3.5-inch drive that combines a spacious 2TB capacity with a speedy 7,200 RPM spindle speed. It uses SMR (Shingled Magnetic Recording) technology and packs a generous 256MB cache, making it perfectly suitable for everyday data storage and backup tasks. This particular version is online retailers-exclusive eco package, delivered in simplified packaging to reduce cost while still carrying the full 2-year manufacturer warranty.
In terms of core specs, this is a 3.5-inch SATA 6Gb/s drive spinning at 7,200 RPM with a 256MB cache. Price-wise, it sits at around 23,000 yen, making it a solid value proposition in the 2TB high-rpm segment. The eco package edition contains the same drive as the retail box version, just with simpler packaging. It's an easy way to add bulk storage to an existing desktop without breaking the bank.

Compatibility Guide

The WD20EZBX-AJP is an internal drive meant for standard 3.5-inch drive bays in desktop PCs. It connects via SATA 6Gb/s, which is supported by virtually all modern motherboards. Power is handled through the standard SATA power connector, and a typical 450W PSU is more than enough for a system with this drive. Note that it won't fit in laptops or mini-PC barebones that lack 3.5-inch bays, so always check your chassis's drive bay sizes first. Because of its SMR nature, the drive is best used as a general-purpose data store rather than in write-heavy setups like NAS boxes.
Installation is straightforward: just connect a SATA data cable and a SATA power cable. Be mindful of cable routing inside the case to avoid interfering with other components. Most mid-tower cases will accommodate it without any trouble.

Product Info

This drive is part of the WD Blue lineup that has been refreshed in the 2020s, and this particular SKU is sold exclusively through online retailers in an eco-friendly package. It occupies the entry-to-mid tier in the HDD market, offering a 2TB capacity at 7,200 RPM for a little over 23,000 yen. With 256MB of cache and a SATA 6Gb/s interface, it delivers solid sequential read speeds for an HDD. The manufacturer backs it with a 2-year warranty, which is standard for the Blue series.
The WD Blue series is renowned for its compatibility testing—Western Digital's F.I.T. Lab runs hundreds of system and platform tests to ensure these drives work reliably in various environments. The eco package not only reduces packaging waste but also keeps the price down, making it an attractive pick for budget-conscious builders.

Best Use Cases

  • Gaming PC data drive: If you store games on an SSD for performance, but have a huge library of screenshots, recordings, or rarely-played titles, this HDD is perfect. The 7,200 RPM speed and 256MB cache keep load times acceptable, though not SSD-fast. It's an excellent companion drive.
  • Creative backup storage: For photographers and video editors who need to archive large RAW files or 4K project libraries, the 2TB capacity offers plenty of room. The drive's reliability and long-term sustained read/write performance make it a dependable backup destination.
  • Budget secondary storage in a custom build: When you want a spacious drive without paying SSD prices, adding this HDD alongside a small boot SSD is a cost-effective solution. It gives you the best of both worlds: fast startup and cheap bulk storage.
    However, it's not ideal for NAS or any environment that involves constant random writes, as SMR technology can cause performance degradation during heavy write operations. Users who need a primary system drive should also look elsewhere—an SSD is a much better choice for that role.

Things to Consider

The biggest caveat is the SMR recording technology. While fine for typical desktop use, it can lead to slower sustained write speeds compared to CMR drives, especially when writing many small files or during long write sessions. For that reason, avoid using it in RAID arrays or as a scratch drive for heavy video editing. The eco package also means the drive arrives in minimal packaging, which may offer less physical protection during shipping—though Western Digital's internal packaging is designed to withstand normal handling. Since it's exclusive to online retailers, you won't find it elsewhere, and pricing can fluctuate. If you're comparing with competing drives like the Seagate BarraCuda, the WD offers strong brand reliability and a solid warranty, but the choice ultimately depends on your specific needs.
Additionally, SMR drives perform best as read-oriented storage solutions. If you plan to constantly rewrite data, a CMR model or an SSD would be a safer investment.
