Dell CXR5D SAS-24GBPS Solid State Drive

Key Specifications at a Glance

With an impressive 800GB capacity and cutting-edge 24GBPS SAS interface, the CXR5D SSD is specifically designed for mixed workload environments where both read and write operations occur frequently. The drive features 512e advanced format with 512-byte emulation, ensuring compatibility with existing systems while optimizing storage efficiency. The inclusion of Self-Encrypting Drive (SED) technology provides hardware-based security without compromising performance.

SAS-24GBPS Interface Technology

The 24GBPS SAS (Serial Attached SCSI) interface represents a significant advancement over previous generation 12GBPS SAS technology, delivering double the bandwidth per lane while maintaining backward compatibility with existing SAS infrastructure. This enhanced interface enables the Dell CXR5D to achieve remarkable data transfer rates, reducing latency and improving overall system responsiveness for critical applications.

Dual-Port Capability for Availability

Unlike SAS SSDs, the SAS interface in the CXR5D supports dual-port functionality, allowing simultaneous connections to multiple host controllers. This architecture enables redundant pathways to storage, eliminating single points of failure and ensuring continuous data availability—a critical requirement for enterprise applications where downtime is not an option.

Enhanced Signal Integrity

The 24GBPS SAS implementation incorporates advanced signal integrity features including improved clock data recovery, enhanced equalization, and superior noise cancellation. These technical improvements allow for reliable operation even in electrically noisy environments typical of densely populated server racks and storage arrays.

Mixed Use Workload Optimization

The "Mixed Use" designation indicates that the Dell CXR5D 800GB SSD is engineered to handle balanced read/write workloads typically found in database applications, virtualization environments, and transaction processing systems. Unlike read-intensive SSDs that prioritize read operations or write-intensive models designed for write-heavy applications, mixed use drives strike an optimal balance for general enterprise applications.

TCG Enterprise Compliance

The SED implementation complies with Trusted Computing Group (TCG) Enterprise specifications, providing standardized security protocols that integrate seamlessly with enterprise security frameworks. This compliance ensures interoperability with major management consoles and security applications, simplifying deployment in regulated environments. A significant advantage of SED technology is the ability to perform near-instantaneous crypto-erase operations by simply discarding the encryption key. This feature enables secure decommissioning or repurposing of drives in seconds rather than the hours required for traditional data sanitization methods, dramatically improving operational efficiency while maintaining security compliance.

512e Advanced Format Technology

The Dell CXR5D employs 512e (512-byte emulation) advanced format technology, which aligns physical sectors on the NAND flash with 4KB boundaries while presenting traditional 512-byte sectors to the host system. This architecture improves error correction efficiency, increases storage density, and enhances data integrity while maintaining full compatibility with existing operating systems and applications.

Improved Error Correction Capabilities

By utilizing larger 4KB physical sectors, the advanced format technology enables more robust error correction algorithms. The additional space within each sector allows for stronger ECC (Error Correcting Code), significantly reducing uncorrectable error rates and improving data reliability, particularly as NAND flash cells approach their endurance limits.

Random Read/Write Performance

For random access patterns—common in database and virtualization environments—the CXR5D provides low-latency response times with high IOPS ratings. The drive's sophisticated queueing algorithms and command processing capabilities efficiently manage multiple concurrent requests, maximizing utilization in multi-threaded application scenarios.

Sequential Transfer Rates

When handling large, contiguous data blocks such as media files, database backups, or scientific datasets, the 24Gbps SAS interface enables remarkable sequential read and write speeds. These high transfer rates significantly reduce data migration windows, backup completion times, and application loading sequences.

Reliability

Each Dell CXR5D 800GB SAS SSD undergoes a rigorous refurbishment process that exceeds industry standards. This comprehensive procedure includes complete diagnostic testing, firmware updates, physical inspection, cleaning, and validation to ensure the drive meets original performance specifications. The refurbishment process not only restores functionality but also verifies long-term reliability.

Diagnostic Testing Protocol

The testing regimen includes full surface scans to identify and remap any marginal memory cells, extended burn-in periods under controlled thermal conditions, interface validation across various host systems, and performance benchmarking against Dell's original specifications. This thorough approach identifies potential failure modes before deployment.

Firmware 

Refurbished drives receive the latest stable firmware revisions from Dell, ensuring compatibility with current server platforms and addressing any known issues from previous versions. Compatibility testing verifies operation across multiple generations of Dell PowerEdge servers and storage arrays, as well as third-party SAS-compatible systems.

Server and Storage Array Integration

The Dell CXR5D 800GB SAS SSD is ideally suited for deployment in Dell PowerEdge servers, Power Vault storage arrays, and compatible third-party systems. The 2.5-inch hot-plug form factor allows for seamless integration into existing infrastructure, while the SAS interface ensures broad compatibility with enterprise storage controllers.

Compatibility

The CXR5D SAS-24GBPS interface maintains backward compatibility with 12GBPS and 6GBPS SAS infrastructures, allowing gradual migration to higher performance levels as infrastructure evolves. The drive operates seamlessly with major SAS host bus adapters and RAID controllers from Dell, Broadcom, Microchip, and other leading manufacturers.

RAID Considerations for SSDs

While SSDs generally offer higher reliability than mechanical hard drives, RAID protection remains important for mission-critical data. RAID configurations should be selected based on performance requirements and fault tolerance needs, with particular attention to rebuild times and impact on drive endurance.
