As enterprise data demands skyrocket in 2025, savvy buyers are scrutinizing HDD price per TB more than ever. With Seagate’s Exos series leading the high-capacity market, understanding true storage value goes beyond simple dollar comparisons. This guide breaks down current pricing trends and reveals what really matters when investing in enterprise drives.
1. Decoding 2025’s HDD Price per TB Landscape
The current average HDD price per TB (Q3 2025) shows interesting segmentation:
- Entry-level SATA (6-10TB): $14.5-$16.2/TB
- Mid-range NAS (12-18TB): $12.8-$14.3/TB
- Enterprise SAS (16-22TB): $15.9-$17.4/TB
- High-capacity SATA (20TB+): $11.2-$12.7/TB
Seagate’s Exos X24 (24TB SATA) currently leads the value proposition at $11.9/TB wholesale, featuring 550TB/year workload rating and PowerBalance technology. However, price alone doesn’t reflect total cost of ownership – enterprise buyers must consider:
- 5-year failure rate (industry avg: 1.8% vs Seagate’s 1.2%)
- Power consumption (W/TB during operation)
- Recertified drive policies
2. Are Higher Capacity Drives Always More Cost-Effective?

- Warranty Efficiency: Seagate’s 3-year limited warranty on Exos drives covers 1,650TB written – sufficient for most enterprise workloads
The sweet spot for most datacenters remains 18-20TB drives, balancing $/TB with manageable rebuild times and compatible infrastructure.
3. How Do SSD Prices Affect HDD Procurement Strategies?
With QLC SSD prices hitting $28/TB (2025 average), hybrid storage architectures are reshaping purchasing decisions:
- Tiered Storage: Hot data on SSDs (15-20% of capacity) with cold data on HDDs delivers optimal $/IOPS
- Seagate’s Dual-Strategy: Their Exos E Series (SSD) and X Series (HDD) share management tools for seamless integration
- Power Comparison: 24TB HDDs consume 5.7W/TB active vs 0.9W/TB for SSDs – crucial for hyperscalers
Forward-looking buyers now evaluate $/TB/Year including electricity costs, where HDDs still lead for archival storage.
