This article covers Western Digital 10TB WD Red Plus NAS 内蔵ハードドライブ HDD.

Overview

The Western Digital WD Red Plus series is purpose-built for NAS (Network Attached Storage) environments, and the WD101EFBX model delivers 10TB of capacity with 7200RPM spindle speed and 256MB cache. What sets this drive apart from the standard WD Red is its use of CMR (Conventional Magnetic Recording) technology instead of SMR (Shingled Magnetic Recording), ensuring consistent write performance in RAID arrays. This 3.5-inch SATA 6Gb/s hard drive is designed for 24/7 operation, making it a solid choice for home NAS units, small office file servers, and media archives. The WD Red Plus series is known for its reliability, with a high MTBF rating and support for up to 180TB/year workload rate. It fits seamlessly into popular NAS enclosures from Synology, QNAP, and ASUSTOR, as well as standard desktop PC cases. Positioned in the mid-range NAS HDD segment, the WD Red Plus competes directly with Seagate's IronWolf series. Its CMR recording gives it a clear advantage over SMR-based drives for users who need stable write performance in RAID 5 or RAID 6 configurations. For home users and small businesses that prioritize data integrity over raw speed, this drive represents a dependable storage foundation.

Compatibility Guide

Interface: SATA 6Gb/s (backward compatible with SATA II 3Gb/s). Form factor: 3.5-inch. Requires a mounting adapter for 2.5-inch bays. Compatible devices: Desktop PCs and NAS systems. Check your NAS manufacturer's compatibility list (Synology, QNAP, ASUSTOR, etc.) for confirmed support. Power connector: Standard SATA 15-pin power connector, compatible with any ATX power supply. RAID support: Works with hardware RAID controllers and motherboard SATA ports. Supports TLER (Time-Limited Error Recovery) for better RAID integration. Note: While it can be used in external USB enclosures, TLER may cause timeouts in non-RAID environments. For external storage, consider a desktop-grade drive instead.

Product Info

The WD101EFBX is part of the refreshed WD Red Plus lineup released in 2021. Pricing typically falls around ¥106,000 JPY on Japan, placing it in the standard range for 10TB NAS HDDs. The drive carries a 3-year manufacturer warranty (regional variations may apply). Market positioning is mid-range. It offers better reliability than entry-level desktop drives but lacks the enterprise-grade endurance of the WD Gold series. The CMR recording technology is the key differentiator from the standard WD Red (SMR), making it suitable for RAID environments where consistent write performance is critical. Key specifications: 10TB capacity, 7200RPM spindle speed, 256MB cache, SATA 6Gb/s interface, 3.5-inch form factor, CMR recording, 180TB/year workload rate.

Best Use Cases

Home NAS users: Ideal for 2-bay NAS systems like Synology DS220+ or QNAP TS-233 for photo backups, media streaming, and file sharing. The CMR technology ensures stable write performance in RAID 1 mirroring. However, if you only need a single drive for basic storage without RAID, a standard WD Red (SMR) may suffice at a lower cost. Small business file server administrators: Perfect for 5-bay or larger NAS setups running RAID 5 or RAID 6. The 7200RPM speed and 256MB cache provide good sequential throughput for large file transfers. Not recommended for 24/7 high-load enterprise environments where WD Gold or Seagate Exos drives would be more appropriate. * Creative professionals for archival storage: Use this drive to archive completed video projects or RAW photo libraries. 10TB can hold dozens of 4K video projects. For active editing workloads, pair it with an NVMe SSD as a cache drive, as HDD random access performance is significantly slower. ## Alternatives
Seagate IronWolf 10TB (ST10000VN0008): A direct competitor with similar CMR technology and 7200RPM speed. IronWolf includes AgileArray technology with RV sensors for multi-bay environments (up to 8 bays). Pricing is comparable, but IronWolf may have better compatibility with QNAP NAS systems. Both are excellent choices; the decision often comes down to brand preference or specific NAS compatibility. Toshiba N300 10TB (HDWG11AA): Another CMR-based NAS HDD with RV sensors and support for up to 8 bays. Typically priced slightly lower than the WD Red Plus, offering better value for budget-conscious buyers. However, some user reviews note that the WD Red Plus runs quieter under load.

Things to Consider

CMR vs. SMR confusion: The WD Red series includes both CMR (WD Red Plus) and SMR (WD Red non-Plus) models. Always verify the model number "WD101EFBX" before purchasing. Using an SMR drive in a RAID array will result in severely degraded write performance. Renewed unit caveats: This specific listing is an Renewed (refurbished) unit. It comes with 's renewed warranty rather than the manufacturer's standard 3-year warranty. While the price is lower, there is inherent risk with used drives.
