Do People Still Use HDD in 2025? Performance Comparison & Cost Analysis

As SSDs dominate consumer markets, many enterprise buyers wonder: Are HDDs still relevant in 2025? Seagate’s latest Exos X24 enterprise HDDs prove that high-capacity hard drives remain indispensable for bulk data storage. With 24TB helium-filled drives offering 40% lower $/TB than SSDs, HDDs continue to thrive in cloud infrastructures and archival systems. This article explores why global procurement teams still prioritize enterprise HDDs like Seagate’s Exos series.

Why Enterprise HDDs Outperform SSDs for Bulk Storage

Seagate’s 2025 technology roadmap reveals HDDs maintain three critical advantages:

  • Cost Efficiency: At $12/TB (Exos X24) versus $30/TB for enterprise SSDs, HDDs save $180,000 per petabyte.
  • Scalability: 24TB models enable 40% fewer servers vs. 8TB SSDs in data centers, reducing power/rack space costs.
  • Longevity: MTBF of 2.5 million hours with 550TB/year workload ratings, backed by 5-year warranties.

Google’s 2024 whitepaper confirms 78% of cold storage still uses HDD arrays due to Seagate’s patented Multi-Actuator tech boosting random IOPS to 500+.

How to Optimize HDD Performance in Modern Server Racks

For buyers deploying Exos X24 drives, follow these 2025 best practices:

  1. Tiered Configuration:Pair with NVMe cache (e.g., Seagate Nytro 3000) for hybrid acceleration.
  2. Environmental Control: Maintain 30-35°C operating temperature using 12Gb/s SAS backplanes.
  3. RAID Setup: RAID 6 with 24+2 disk groups minimizes rebuild times (18hrs vs. 72hrs for RAID 5).

Future-Proofing Your HDD Investment: 30TB+ HAMR Roadmap

Seagate’s Heat-Assisted Magnetic Recording (HAMR) technology, launching in Q3 2025, will deliver:

  • 30TB+ capacities with unchanged form factors
  • 20% lower power consumption per PB
  • Backward compatibility with existing JBOD enclosures

Industry analysts project HDDs will hold 65% of exabyte storage share through 2028 (Coughlin Associates).
