As global demand for high-capacity enterprise storage surges in 2025, the Seagate Exos 7E8 series has emerged as a top choice among bulk HDD buyers. With 16TB-24TB models dominating datacenter deployments, understanding this workhorse drive’s real-world value is crucial for procurement professionals. Let’s break down what makes these helium-sealed drives stand out in today’s competitive storage market.
Decoding the Exos 7E8 Series: Model Comparison
The 7E8 lineup offers three tiers optimized for different workloads:
- ST16000NM003D: Base model (16TB/256MB cache/7200 RPM) – $289-$315 bulk pricing
- ST18000NM004D: Mid-range (18TB/256MB cache) – 15% better $/TB at $327-$348
- ST24000NM008D: Flagship (24TB/512MB cache) – Industry-leading 550TB/yr workload rating
Real-world benchmarks show the 24TB variant delivers 282MB/s sustained transfer speeds, making it ideal for hyperscale cold storage. All models feature PowerBalance technology, reducing operational power by up to 18% compared to previous gen.
Why Are Hyperscalers Migrating to 24TB Models in 2025?
Three key factors drive the shift:
- Rack Space Efficiency: 24TB drives allow 4.5PB per standard 42U rack versus ** B with 16TB units
- TCO Advantage: New helium retention tech extends service life to 7 years in 30°C environments
- Sustainability: 37% lower Watts/TB than 2020-era HDDs, critical for carbon-conscious datacenters
Google’s latest white paper confirms 24TB adoption cuts storage OPEX by $1.2M per 10PB deployment over 5 years.
