About the Seagate Exos 2X24 Dual-Actuator 24TB HDD
Supporting SAS and dual-port connectivity, the Seagate Exos 2X24 is a 24TB enterprise-class hard drive engineered for high-throughput storage architectures. This 3.5-inch, helium-sealed drive delivers sustained transfer rates up to 285 MB/s per actuator and features Seagate's dual-actuator MACH.2 technology, which presents two independent logical units (LUNs) to the host system, effectively doubling I/O parallelism within a single drive form factor. The Exos 2X24 (part number ST24000NX0402) combines massive capacity with reliability metrics designed for demanding data center environments: 2,500,000 hours MTTF, an annualized workload rating of 550TB/year, and a non-recoverable read error rate of 1 per 10^15 bits read.
Built for storage architects and IT procurement teams managing petabyte-scale deployments, this Seagate drive supports both 512e and 4Kn sector formats, offers 256MB cache, and operates at 7200 RPM. Dual-port SAS connectivity (12Gb/s) ensures redundant pathways in high-availability clusters. The drive includes PowerChoice support for multiple power-saving states, with typical idle consumption near 9.0W. A Self-Encrypting Drive (SED) option is available on select model variants for compliance-critical workloads. The combination of dual-actuator architecture, enterprise-grade reliability, and scalable capacity makes the Exos 2X24 ideal for organizations seeking to consolidate storage infrastructure without sacrificing performance or uptime.
Enterprise Deployment Scenarios
- High-performance RAID arrays in data centers requiring maximum throughput and parallel I/O per chassis slot
- Nearline archival systems balancing 550TB/year workload capacity with long-term retention demands
- Redundant storage clusters leveraging dual-port SAS for fault-tolerant multi-path access
- Large-scale backup and disaster recovery environments where 24TB capacity reduces drive count and power overhead
- Mission-critical databases and analytics platforms benefiting from dual independent actuators and SED encryption options
