When building a data storage infrastructure, understanding the three core types of hard drives is critical for IT managers and bulk buyers. As Seagate’s global enterprise distributor, we break down HDDs, SSDs, and hybrid drives with 2025 market insights to help procurement specialists make informed decisions.
1. HDDs (Hard Disk Drives): The Workhorse of Bulk Storage
Seagate’s Exos X24 enterprise HDDs dominate high-capacity deployments with 24TB/platter helium technology (Q3 2025 pricing: $0.018/GB). These spinning magnetic drives excel in cold storage and data centers requiring low $/TB ratios.
2. SSDs (Solid State Drives): Performance Powerhouses
Seagate’s Nytro 5000 series NVMe SSDs (priced at $0.32/GB in volume orders) offer 700K IOPS and 6.8GB/s sequential reads – ideal for AI training datasets. Unlike HDDs, NAND flash-based SSDs have no moving parts, reducing failure rates to 0.5% annually versus 2.1% for HDDs (Backblaze 2025 reliability report).
3. SSHDs (Solid State Hybrid Drives): Balanced Solutions
The FireCuda ZU series combines 4TB HDD capacity with 128GB SSD cache, automatically migrating frequently accessed data. Benchmark tests show 380% faster boot times versus standard HDDs at just 18% cost premium over HDD-only solutions – perfect for edge computing nodes.
Current Market Trends Affecting Drive Selection
The rising $/TB gap (HDDs at $18/TB vs SSDs at $320/TB) makes hybrid arrays increasingly popular for tiered storage architectures.
