Wd Cmr Hdd
Overview
Product sourcing insights & recommendations
The phrase "wd cmr hdd" refers to Western Digital hard drives utilizing Conventional Magnetic Recording (CMR) technology. Unlike Shingled Magnetic Recording (SMR), which overlaps data tracks to increase density at the cost of write performance, CMR writes tracks side-by-side, offering consistent high-speed performance ideal for NAS, RAID, and enterprise workloads WesterndigitalSalvagedata.
Market Trends & Insights (2026)
The HDD market is currently experiencing a "renaissance" driven by the AI gold rush LeilFacebook:
- Price Hikes: As of early 2026, HDD prices have surged due to intense demand from AI data centers. Hyperscalers are prioritizing high-capacity drives (26TB+), leading to supply shortages and 15–20% price increases in the consumer channel (4TB–12TB) Facebook.
- AI Infrastructure: AI workloads generate vast training datasets that require cost-effective, high-capacity storage. Western Digital has responded with record-breaking 26TB CMR and 32TB UltraSMR drives to meet these exascale needs WesterndigitalStoragereview.
- Capacity Leaders: The industry has transitioned to 11-disk designs and ePMR (energy-assisted PMR) to push capacities beyond 30TB while maintaining reliability Westerndigital.
WD CMR Product Identification
Identifying CMR vs. SMR is critical for NAS and RAID users to avoid performance degradation.
- WD Red Plus/Pro: These lines are strictly CMR (e.g., WD40EFZZ, WD80EFPX). Standard "WD Red" drives often use SMR (e.g., WD40EFAX) and should be avoided for active RAID environments NascomparesServethehome.
- WD Gold / Ultrastar: Designed for data centers, these are all CMR (standard) or UltraSMR (specifically labeled for cloud usage) WesterndigitalWesterndigital.
- WD Blue: Larger capacities (2TB–6TB) in the Blue line are mostly SMR, while the 1TB and 8TB models (WD80EAZZ) remain CMR NascomparesTechpowerup.
I have compiled detailed lists of current Western Digital CMR products and verified suppliers specializing in high-capacity enterprise and NAS storage. The files below include pricing, capacity options (up to 26TB), and supplier profiles for sourcing.
