Key Specifications

The Dell 345-BHYP delivers enterprise-level performance metrics that meet the rigorous demands of modern data center operations. With its 240GB capacity, the drive provides ample storage for operating systems, hypervisors, and essential applications while maintaining the endurance characteristics required for 24/7 operation.

Interface and Form Factor Specifications

Utilizing the SATA-6Gbps interface through the M.2 form factor, the 345-BHYP achieves compatibility with a wide range of enterprise systems while maximizing performance within the SATA interface limitations. The M.2 2280 specification (22mm wide, 80mm long) ensures broad compatibility with server motherboards and BOSS card adapters designed for this form factor.

SATA 6Gbps Interface Performance

The Serial ATA revision 3.0 interface provides maximum theoretical transfer speeds of 6Gbps (600MB/s), which the 345-BHYP effectively utilizes for sequential read and write operations. This interface choice ensures compatibility with existing server infrastructure while providing sufficient bandwidth for boot operations and moderate storage workloads.

M.2 Form Factor Advantages

The M.2 form factor provides significant space savings compared to traditional 2.5-inch drives, allowing for more efficient server designs and increased storage density. The compact footprint enables deployment in space-constrained environments while maintaining enterprise-level reliability and performance characteristics.

Storage Technology: 3D NAND TLC Architecture

At the heart of the 345-BHYP lies advanced Triple-Level Cell (TLC) 3D NAND flash memory, which stacks memory cells vertically to achieve higher densities and improved performance characteristics compared to planar NAND technologies. This architecture enables the 240GB capacity while maintaining the endurance and reliability standards required for enterprise deployment.

3D NAND Cell Structure

The three-dimensional NAND structure stacks memory cells in multiple layers, significantly increasing storage density without compromising cell integrity. This vertical arrangement reduces cell-to-cell interference and improves write endurance compared to planar TLC NAND, making it suitable for the write-intensive demands of server boot applications.

TLC NAND Enterprise Optimization

While TLC NAND stores three bits per cell, the enterprise-grade implementation in the 345-BHYP incorporates advanced error correction, wear leveling, and over-provisioning to ensure data integrity and extended lifespan. These optimizations differentiate enterprise TLC from consumer-grade implementations, providing the reliability necessary for critical infrastructure.

Performance Metrics and Capabilities

The Dell 345-BHYP is engineered to deliver consistent performance under the varied workload conditions encountered in enterprise environments. Unlike consumer SSDs that may exhibit performance degradation under sustained writes, the 345-BHYP maintains predictable performance through advanced firmware algorithms and enterprise-focused design.

Sequential Read and Write Performance

With sequential read speeds reaching up to 540MB/s and sequential write speeds up to 500MB/s, the 345-BHYP provides rapid data access for boot operations and large file transfers. These performance characteristics ensure minimal wait times during system initialization and efficient handling of sequential workload patterns.

Random I/O Performance

The drive delivers exceptional random I/O performance, with random 4K read operations reaching up to 90,000 IOPS and random 4K write operations achieving up to 70,000 IOPS. This high random performance is crucial for operating system and application responsiveness, particularly in virtualized environments where multiple virtual machines generate concurrent I/O requests.

Sustained Performance Characteristics

Enterprise workloads often involve sustained write operations that can challenge consumer-grade SSDs. The 345-BHYP incorporates advanced write acceleration technologies and sufficient over-provisioning to maintain consistent performance during extended write sequences, preventing the performance degradation commonly observed in non-enterprise SSDs.

Endurance and Reliability Specifications

Enterprise storage demands exceptional endurance and reliability, and the Dell 345-BHYP is engineered to meet these rigorous requirements. With comprehensive protection features and robust construction, this SSD delivers the dependable performance necessary for always-on enterprise infrastructure.

Terabytes Written (TBW)

The 345-BHYP 240GB model is rated for substantial write endurance, typically supporting hundreds of terabytes written over its operational lifespan. This TBW rating ensures the drive can handle the frequent write cycles associated with operating system updates, logging, and temporary file operations throughout its deployment in server environments.

Uncorrectable Bit Error Rate (UBER)

The drive features an uncorrectable bit error rate of less than 1 sector per 10^17 bits read, significantly better than consumer-grade SSDs. This exceptional error rate ensures data integrity and reduces the risk of data corruption, a critical consideration for enterprise storage where data accuracy is paramount.

Power Loss Protection Mechanisms

While the 345-BHYP operates within the BOSS card framework, it incorporates data protection features that help maintain data integrity during unexpected power events. These mechanisms ensure that in-flight writes are properly managed and that the drive's mapping tables remain consistent, preventing data corruption during power transitions.

Deployment Scenarios

The Dell 345-BHYP is designed for seamless integration with Dell PowerEdge servers and compatible systems, providing optimized performance when deployed as part of a comprehensive server solution. Understanding the appropriate deployment scenarios ensures maximum benefit from the drive's enterprise capabilities.

Dell PowerEdge Server Integration

Specifically engineered for Dell PowerEdge servers, the 345-BHYP delivers plug-and-play compatibility when installed in designated BOSS card slots. This integration ensures optimal performance, proper thermal management, and comprehensive management through Dell's integrated management tools.

Virtualization Workload Optimization

When used as a boot device in virtualized environments, the 345-BHYP delivers the consistent low-latency performance necessary for hypervisor operation. The drive's random I/O capabilities ensure responsive virtual machine performance, even when multiple VMs generate concurrent storage requests.
