Seagate 3KS233-151 Enterprise Hard Drive

Enterprise Storage Redefined

The Seagate 3KS233-151 Exos X24 24TB enterprise hard drive represents the pinnacle of high-capacity storage technology, engineered specifically for demanding data center environments and enterprise storage applications. As part of Seagate's flagship Exos enterprise storage portfolio, the X24 series delivers exceptional performance, reliability, and scalability for organizations managing massive datasets and requiring uninterrupted access to critical business information.

Key Specifications

Storage Capacity

The Seagate 3KS233-151 EXOS X24 features an industry-leading 24TB storage capacity, achieved through Seagate's advanced Helium-filled platform and innovative recording technologies. This massive storage density enables enterprises to maximize their storage footprint while minimizing total cost of ownership. The drive utilizes conventional magnetic recording (CMR) technology rather than shingled magnetic recording (SMR), ensuring consistent performance and compatibility with all enterprise workloads.

HelioSeal Technology Benefits

Seagate's proprietary HelioSeal technology hermetically seals the drive with helium, which is less dense than air, resulting in reduced drag on the spinning platters. This innovative approach enables higher areal density, lower power consumption, and improved thermal efficiency compared to traditional air-filled drives. The helium-filled design contributes directly to the drive's 24TB capacity while maintaining reliability and performance standards.

Performance Characteristics

Rotational Speed and Interface

Operating at 7200 RPM with a SAS 12GB/s interface, the 3KS233-151 Exos X24 delivers enterprise-class performance suitable for the most demanding storage applications. The SAS interface provides full duplex capability, allowing simultaneous read and write operations, and offers enhanced error recovery controls, domain segmentation, and improved connectivity for multi-drive environments. The 12GB/s data transfer rate ensures minimal bottlenecks in high-throughput scenarios.

Cache and Data Transfer Rates

Equipped with a substantial 512MB cache buffer, the Exos X24 efficiently manages data flow between the host system and the drive platters. This large cache size helps maintain consistent performance during sustained read and write operations, particularly important in RAID configurations and sequential workload scenarios. The drive sustains high data transfer rates critical for enterprise applications requiring rapid access to large files and datasets.

Physical Specifications and Form Factor

Dimensions and Compatibility

The 3KS233-151 Exos X24 maintains the standard 3.5-inch form factor, ensuring broad compatibility with existing enterprise server and storage system infrastructure. Measuring 101.85mm x 146.05mm x 26.11mm, the drive fits seamlessly into enterprise server bays, storage arrays, and data center racks without requiring special mounting hardware or enclosures.

Reliability and Endurance Features

Workload Rate Limit

Rated for 550TB per year workload, the Exos X24 can handle intensive enterprise applications and write-heavy workloads. This substantial workload rating makes the drive suitable for applications requiring constant data access and modification, including large-scale databases, virtualization environments, and content delivery networks.

Error Rate and Data Integrity

With an unrecoverable read error rate of 1 per 10^15 bits read, the Exos X24 provides exceptional data integrity for mission-critical applications. This low error rate, combined with advanced error correction capabilities, ensures data remains intact and accessible throughout the drive's operational lifespan.

Advanced Technology Integration

Power Consumption Specifications

The 3KS233-151 Exos X24 demonstrates impressive power efficiency despite its high capacity and performance. Typical power consumption during active operations ranges between 6.8W to 8.5W, while idle power consumption drops to approximately 5.5W. The drive supports multiple power modes, including standby and sleep states, enabling additional power savings in appropriately configured environments.

Efficiency per Terabyte

When calculated on a watts-per-terabyte basis, the Exos X24 represents one of the most power-efficient high-capacity enterprise drives available. This efficiency translates to reduced operational costs and cooling requirements in large-scale deployments, contributing significantly to lower total cost of ownership.

Enterprise-Class Features and Technologies

Data Security and Protection

The 3KS233-151 Exos X24 series includes optional self-encrypting drive (SED) models that provide comprehensive data security through hardware-based encryption. These drives offer TCG Enterprise and IEEE 1667 compliance, enabling seamless integration into existing security frameworks without performance degradation.

Power Loss Protection

Advanced power loss protection circuits safeguard data in transit during unexpected power interruptions. This feature ensures that data being written to the drive is protected and that the drive maintains its operational integrity following power restoration.

Application and Use Case Scenarios

Data Center Deployment

The Exos X24 excels in cloud storage applications where high capacity, reliability, and power efficiency are paramount. Its 24TB capacity enables cloud providers to maximize storage density while maintaining performance standards for diverse workload requirements.

Big Data and Analytics

For organizations processing large datasets for business intelligence and analytics, the Exos X24 offers the capacity to store massive datasets locally while providing the throughput needed for data processing operations. The drive's high sustained transfer rates benefit sequential read and write patterns common in big data applications.

Database and Transaction Processing

In database applications, the 3KS233-151 Exos X24 delivers the random I/O performance necessary for efficient transaction processing and query execution. The combination of high capacity and performance makes it suitable for large-scale database deployments where both storage capacity and access speed are critical.
