Seagate Exos X20 20TB 7200RPM SATA 6Gb/s 3.5-inch 512e Enterprise HDD (Bulk)

The Seagate Exos X20 is a 20TB 3.5-inch enterprise-class hard disk drive engineered for high-density datacenter deployments demanding sustained throughput, reliability, and scalability. Built on Seagate's proven HelioSeal hermetically sealed helium platform, the Exos X20 packs ten disk platters into a standard 3.5-inch form factor, enabling industry-leading areal density while reducing power consumption and operational vibration compared to air-filled designs. The drive operates at 7200 RPM and interfaces via SATA 6Gb/s, delivering up to 285 MB/s sustained transfer rates suited to sequential-read-intensive enterprise environments.

The Exos X20 targets hyperscale storage infrastructure, cloud object storage, and high-capacity NAS or JBOD arrays where per-rack capacity and total cost of ownership are primary considerations. It carries a 2.5 million hour MTBF rating and is rated for 550 TB per year workload, reflecting continuous 24×7 operational duty cycles typical of enterprise datacenters. Integrated PowerChoice technology enables configurable power states to optimize energy efficiency across idle and active periods, while advanced vibration compensation (dual-plane balance and rotational vibration sensors) ensures consistent performance in high-density multi-drive enclosures.

The drive ships in Bulk packaging under manufacturer part number ST20000NM007D, making it well suited for large-scale infrastructure procurement and system integration programs. The 512e (512-byte emulation) sector format maintains compatibility with legacy enterprise operating systems and storage controllers while the physical 4Kn sector structure underpins data integrity. Seagate's proprietary cache algorithms and on-drive DSP deliver consistent latency profiles for AI training data lakes, backup repositories, video surveillance archives, and cold-tier object storage workloads across UAE, GCC, EMEA, and APAC datacenter deployments.

Ideal for

• Hyperscale and cloud datacenter object storage requiring maximum raw capacity per rack unit
• AI and machine learning training data lakes where large sequential dataset reads drive throughput demands
• Centralized backup and disaster recovery repositories with continuous high-duty-cycle write workloads
• High-density NAS and JBOD scale-out storage arrays in enterprise private cloud environments
• Cold-tier and nearline archive storage for media, surveillance footage, and compliance data retention
• High-capacity video surveillance recording infrastructure with multiple concurrent HD stream ingestion
