This article covers ウエスタンデジタル(Western Digital) WD60EFPX [WD Red Plus（6TB 3.5インチ SATA 6G 5400rpm 256MB CMR）].

Overview

Western Digital's WD Red Plus series is purpose-built for NAS environments, and the WD60EFPX is a 6TB model that delivers reliable, consistent performance. This 3.5-inch hard drive uses a SATA 6Gbps interface, spins at 5400 RPM, and packs 256MB of cache. The key differentiator here is CMR (Conventional Magnetic Recording) technology, which avoids the write-performance degradation that plagues SMR drives in RAID arrays. Designed for systems with up to 8 bays, the WD60EFPX targets home users and small-to-medium businesses who need dependable 24/7 operation. With a workload rate of 180TB per year and a 3-year limited warranty, it's a solid mid-range choice for anyone building a NAS for file sharing, backups, or media streaming. The drive runs Western Digital's NASware firmware, which optimizes error recovery and reduces compatibility issues with popular NAS enclosures. In the competitive landscape, the WD Red Plus sits between the entry-level WD Blue (desktop-oriented, no NAS optimizations) and the high-performance WD Red Pro (7200 RPM, higher workload rating). Its main rivals are Seagate's IronWolf series and Toshiba's N300 series, but the WD60EFPX stands out for its clear CMR labeling and broad NAS vendor compatibility.

Compatibility Guide

The WD60EFPX is a standard 3.5-inch SATA HDD. It works with any SATA 6Gbps or 3Gbps port, though the latter will limit throughput. Bay support: Rated for up to 8-bay NAS systems. Compatible with Synology, QNAP, ASUSTOR, Netgear, and other major brands. Always check your NAS vendor's compatibility list before purchasing. Form factor: 3.5-inch only. Will not fit in 2.5-inch bays without an adapter. RAID: CMR technology means stable performance in RAID 0, 1, 5, 6, 10, and other common levels. No write cliff issues associated with SMR drives. Interface: SATA 6Gbps, backward compatible with SATA 3Gbps. Cable not included. * File system: NAS-side formatting (ext4, Btrfs, ZFS, etc.) is fully supported.

Product Info

The WD60EFPX is a current-generation 6TB model in the WD Red Plus lineup, launched around 2022. It occupies the mid-range tier for NAS hard drives, balancing cost, capacity, and reliability. Model: WD60EFPX Capacity: 6TB Rotational speed: 5400 RPM Cache: 256MB Interface: SATA 6Gbps Form factor: 3.5-inch Recording technology: CMR Workload rate: 180TB/year * Warranty: 3 years (limited) Market positioning: entry-to-mid-range NAS HDD. It sits below the WD Red Pro (7200 RPM, higher endurance) and above the WD Blue (desktop, no NAS optimizations). The CMR recording and NASware firmware make it a reliable choice for RAID-based storage.

Best Use Cases

Home NAS user: Running a 2-bay Synology or QNAP for photo backups and document storage. Pair two WD60EFPX drives in RAID 1 for 6TB of mirrored, safe storage. The CMR technology ensures consistent write speeds during backups. Small office file server: A 4-bay NAS with WD60EFPX drives in RAID 5 gives about 18TB usable capacity. The 180TB/year workload rate handles daily file sharing for a small team without issue. Media streaming server: Plex or Emby libraries with 4K movies and TV shows. 6TB holds roughly 300 4K movies or 1,500 HD movies. The 5400 RPM speed is adequate for direct playback, though transcoding may benefit from an SSD cache. Long-term archive: For data that is written once and read occasionally, the CMR drive maintains stable performance over years. No SMR-related write degradation over time. Not ideal for: Users needing 10TB+ per drive (consider WD Red Plus 10TB+ or WD Red Pro). High-speed workloads like video editing (use an SSD or 7200 RPM drive). * Budget-constrained builds (WD Blue or Seagate BarraCuda are cheaper, but lack NAS optimizations).

Things to Consider

Speed: At 5400 RPM, sequential read/write speeds hover around 200 MB/s. This is fine for media streaming and backups, but not for heavy random I/O or real-time editing. Capacity: 6TB is modest by 2026 standards. If you anticipate rapid growth, consider 8TB or 10TB models to avoid early upgrades. Warranty: 3 years is standard for this class. WD Red Pro and Seagate IronWolf Pro offer 5-year warranties for a higher price. Competition: Seagate IronWolf (ST6000VN001) is often slightly cheaper. Toshiba N300 (HDWG460) runs at 7200 RPM for better performance. Check your NAS vendor's compatibility list before buying. * Internal only: This is an internal drive. For external USB use, you'll need a separate SATA-to-USB adapter or enclosure. ## FAQ
Q: Can I use this drive in a RAID 5 array? A: Yes, absolutely. The CMR recording technology ensures stable write performance even under RAID 5 parity calculations. Unlike SMR drives, you won't experience severe write degradation during rebuilds. However, always maintain a separate backup for critical data. Q: What's the difference between WD Red Pl
