Overview

The Western Digital WD Red Plus 10TB (model WD100EFB) is a 3.5-inch internal hard drive purpose-built for NAS environments. It spins at 7200 RPM class speed, packs 256MB of cache, and uses Conventional Magnetic Recording (CMR) technology for reliable RAID performance.
This drive targets small-to-medium business NAS setups as well as home NAS users who need a large, dependable storage pool for file sharing, backups, and media archives. WD Red Plus drives are designed and tested for up to 8-bay NAS systems, and they work well with ZFS and other advanced file systems.
In the market, the WD Red Plus sits in the mid-range tier for NAS HDDs. It offers a good balance of reliability and cost, sitting below the enterprise-grade WD Gold and WD Red Pro lines but above basic desktop drives. For SOHO and home users, it's a sweet spot.

Compatibility Guide

The drive uses a standard SATA 6Gb/s interface and a 3.5-inch form factor, making it compatible with most NAS enclosures and desktop PC cases that have a 3.5-inch bay.

  • Interface: SATA 6Gb/s (SATA III)
  • Form factor: 3.5-inch
  • Recommended bay count: Up to 8 bays (per manufacturer)
  • Power: Standard SATA power connector
    Be aware that this drive cannot be installed in 2.5-inch-only chassis or laptops. Also, some older NAS models may not support drives larger than 4TB or 6TB, so always check your NAS's compatibility list before purchasing.

Product Info

The WD Red Plus 10TB (WD100EFB) was released around 2022. Its price hovers around ¥171,312 (as of October 2026 on Japanese online retailers). The warranty period is 3 years.
Key specifications:

  • Capacity: 10TB
  • Rotational speed: 7200 RPM class
  • Cache: 256MB
  • Recording technology: CMR
  • Interface: SATA 6Gb/s
  • Form factor: 3.5-inch
  • Annual workload rate: 180TB/year
    Market positioning: Mid-range NAS HDD. It's not as rugged as enterprise drives but offers sufficient reliability for SOHO and home use. The CMR technology ensures consistent performance in RAID arrays.

Best Use Cases

  • Home NAS users: Ideal for centralizing family photos, videos, and documents. 10TB provides ample space for years of data. Pairing two drives in RAID 1 or using RAID 5 with three or more drives gives redundancy.
  • Small office / SOHO: Perfect for file servers and backup targets. Multiple drives in an 8-bay NAS can create a multi-terabyte storage pool. CMR helps maintain performance during RAID rebuilds.
  • Creative professionals for archiving: Store completed video projects, raw footage, or design files that don't need fast access. The large capacity and relatively low cost per terabyte make it a good nearline storage solution.
    Not recommended for:
  • OS or application drives: Random access performance is far slower than SSDs. Use an SSD for boot and active projects.
  • 24/7 high-workload environments: Enterprise drives like WD Gold or WD Red Pro have higher workload ratings (300TB/year) and longer warranties. The WD Red Plus is rated for 180TB/year.

Things to Consider

First, confirm that your NAS supports 10TB drives. Some older models have a maximum capacity limit (e.g., 4TB or 6TB). Check the manufacturer's compatibility list before buying.
Second, the 7200 RPM class speed means slightly more noise and heat compared to 5400 RPM drives. If your NAS is in a quiet living room, you might prefer the 5400 RPM version (WD100EFA), though that model has lower sequential performance.
Third, while WD Red Plus uses CMR, older WD Red (non-Plus) drives sometimes used SMR, which caused performance issues in RAID. If you're buying used, verify the model number to avoid SMR drives.
Finally, price: at around ¥171,312, this drive is on the higher side compared to competitors like Seagate IronWolf 10TB. However, WD's reputation for reliability and the 3-year warranty may justify the premium for some users.

FAQ

Q: Can I use this HDD in a PS5 or Xbox Series X?
A: No, the 3.5-inch form factor is too large for internal installation in consoles. You could put it in an external USB enclosure and use it for extended storage, but don't expect SSD-like load times.
Q: How many drives can I use in a RAID array?
A: WD recommends up to 8 bays. CMR technology ensures that RAID rebuilds are faster and more reliable than with SMR drives. For best results, use identical drives with the same firmware.
Q: What's the difference between WD Red Plus and WD Red Pro?
A: WD Red Pro offers a higher annual workload rate (300TB/year), a 5-year warranty, and is designed for 24/7 operation in mid-range NAS systems. WD Red Plus has a 180TB/year rating and a 3-year warranty, making it more suitable for SOHO and home use. The price difference is roughly 20-30%.
