Seagate Exos M 30TB Enterprise 3.5" Hard Drive (HDD), Helium Sealed CMR, 7200 RPM, 512MB Cache, SATA 6Gb/s, 2.5M MTBF | ST30000NM004K

Dominate data growth with the Seagate Exos M 30TB Enterprise HDD. As data requirements for AI, cloud storage, and high-definition surveillance surge in 2026, the ST30000NM004K provides the highest density available in a standard 3.5-inch form factor. This drive isn't just about raw capacity; it’s about enterprise-grade reliability and performance efficiency, ensuring your data is accessible, secure, and cost-effective to store.

Key Features

• Massive 30TB CMR Capacity: Unlike SMR drives that can suffer from slower rewrite speeds, the Exos M uses Conventional Magnetic Recording (CMR). This ensures consistent, high-speed performance for random write workloads, making it ideal for RAID arrays and high-performance servers.
• Helium-Sealed Reliability: The drive features a hermetically sealed helium design. Helium reduces internal air friction and turbulence, allowing for more platters in a single drive while lowering power consumption and increasing mechanical longevity.

• Optimized Power Efficiency: Equipped with PowerChoice™ and PowerBalance™ technologies, this drive allows data centers to tailor their power usage. PowerChoice™ provides customizable idle power savings, while PowerBalance™ optimizes the watts-per-terabyte ratio without sacrificing IOPS.

  Superior Data Integrity: With a 2.5 million-hour MTBF and an Annualized Failure Rate (AFR) of just 0.35%, the Exos M is built for the most rigorous 24/7/365 environments. It also features RSA 3072 firmware verification to protect against unauthorized firmware tampering.

Performance / Data Center Efficiency The ST30000NM004K delivers a maximum sustained transfer rate of 275 MB/s, ensuring that massive data migrations and backups happen as quickly as possible. A large 512MB multi-segmented cache improves small-block performance, while the 7200 RPM spindle speed maintains the low latency (4.16 ms) required for enterprise applications.
