This article covers Western Digital HDD 8TB WD Red Plus NAS RAID (CMR) 3.5インチ 内蔵HDD WD80EFAX-EC 【国内正規代理店品】.
Overview
The Western Digital WD Red Plus series is designed specifically for NAS and RAID environments, offering a balance of reliability and performance. The WD80EFAX-EC model provides 8TB of storage capacity using CMR (Conventional Magnetic Recording) technology, which ensures consistent write performance in RAID arrays. With a 5400RPM spindle speed and 256MB cache, this drive is optimized for 24/7 operation in multi-bay NAS systems. It is an excellent choice for home servers, media storage, and data backup.
Compatibility Guide
This 3.5-inch internal hard drive uses a standard SATA 6Gb/s interface, making it compatible with most desktop PCs, NAS enclosures, and external drive docks that support 3.5-inch drives. Ensure your system has an available 3.5-inch drive bay and a SATA data cable. For RAID configurations, using identical drives from the same series is recommended for optimal performance. Note that this drive cannot be installed in laptops or small form factor cases that only accommodate 2.5-inch drives.
Product Info
The WD80EFAX-EC is part of Western Digital's WD Red Plus lineup, positioned as a mid-range NAS HDD. It features CMR technology, which is superior to SMR for RAID environments, and comes with a 3-year warranty. Available through major retailers like this drive is a reliable choice for users who need cost-effective, high-capacity storage with proven durability.
Best Use Cases
- NAS Enthusiasts: Ideal for users running Synology, QNAP, or custom NAS systems. The CMR technology ensures stable performance during RAID rebuilds and heavy write workloads. Not recommended for users who need ultra-fast access speeds—consider an SSD for that.
- Home Server Builders: Perfect for building a home file server or media server. The 8TB capacity provides ample space for photos, videos, and documents. It is designed for continuous operation, so it can run 24/7 without issues. However, if noise is a concern, the 5400RPM drive may still produce audible seek sounds.
- Backup Storage: Suitable for use as a backup drive inside an external enclosure. The CMR reliability makes it a trustworthy option for long-term data retention. Not ideal for frequent random read/write workloads like gaming or database applications.
Things to Consider
The 5400RPM rotational speed means sequential transfer rates are lower than 7200RPM drives. If you frequently transfer large files, consider the WD Red Pro series for higher performance. Additionally, WD Red Plus drives are priced higher than the standard WD Red (SMR) models. For non-RAID or light usage, SMR drives may suffice, but for RAID arrays, CMR is strongly recommended. Also, this is an internal drive; you will need a separate enclosure if you plan to use it externally. Finally, ensure your system has a free 3.5-inch bay before purchasing.
FAQ
Q: Can I use this HDD as an internal drive in a PS5 or Xbox Series X?
A: No, this is a 3.5-inch internal HDD and does not fit in consoles. For external storage on consoles, you would need a USB enclosure, but performance may be limited.
Q: What is the difference between WD Red (SMR) and WD Red Plus (CMR)?
A: WD Red Plus uses CMR technology, which provides consistent write performance in RAID environments. WD Red (SMR) is cheaper but can suffer from performance degradation during RAID rebuilds. For NAS and RAID use, WD Red Plus is the recommended choice.
Q: Can I use this drive as a system drive in a desktop PC?
A: Technically yes, but the 5400RPM speed will be a bottleneck for OS and application loading. It is better suited for data storage, media libraries, or backups. Use an SSD for your operating system.
