345-BEYR Dell Gen4 PCIe 15.36TB NVMe U.2 SFF SSD

Interface and Protocol Architecture

PCIe Gen4 Throughput Advantages

The Dell 345-BEYR SSD utilizes the PCIe Gen4 x4 interface, offering up to 16GT/s per lane and a total bandwidth of 64GT/s. This translates to sequential read speeds exceeding 7,000MB/s and write speeds up to 3,500MB/s. Compared to PCIe Gen3, Gen4 doubles the data transfer rate, enabling faster access to large datasets and reducing latency across enterprise workloads.

NVMe Protocol Optimization

Built on the NVMe 1.4 protocol, the 345-BEYR SSD supports multiple parallel command queues, reducing CPU overhead and improving IOPS performance. NVMe’s streamlined architecture allows for efficient communication between the SSD and host system, making it ideal for high-concurrency environments such as virtual machines, containerized applications, and distributed databases.

U.2 Interface and Hot-Plug Support

The U.2 interface provides enterprise-grade connectivity and supports hot-plug functionality, allowing administrators to replace or upgrade drives without system downtime. This feature is essential for mission-critical systems requiring continuous availability. The U.2 connector also supports integration with backplane architectures, simplifying deployment in rack-mounted servers and storage arrays.

Form Factor

2.5-Inch Small Form Factor (SFF)

The Dell 345-BEYR SSD is housed in a 2.5-inch SFF enclosure, ensuring compatibility with Dell PowerEdge servers and other enterprise platforms. This compact form factor enables high-density storage configurations, maximizing rack space utilization. The drive’s mechanical design supports tool-less installation and removal, facilitating rapid deployment and maintenance.

Performance Metrics

Sequential and Random Performance

• Sequential Read: Up to 7,000MB/s
• Sequential Write: Up to 3,500MB/s
• Random Read IOPS: Up to 1,000,000
• Random Write IOPS: Up to 180,000

These performance metrics position the Dell 345-BEYR SSD as a top-tier solution for read-intensive workloads. Applications such as real-time analytics, AI inference, and media streaming benefit from its high throughput and low latency.

Endurance and Reliability

1DWPD Endurance Rating

With a 1 Drive Write Per Day (DWPD) rating over a five-year lifespan, the Dell 345-BEYR SSD supports approximately 15.36TB of data writes daily. This endurance level is ideal for read-centric environments where write operations are infrequent. It balances performance, reliability, and cost-efficiency for applications such as archival storage, VDI, and web hosting.

MTBF and Data Integrity Features

The drive boasts a Mean Time Between Failures (MTBF) exceeding 2.5 million hours, ensuring long-term reliability. It includes end-to-end error correction code (ECC), power-loss protection capacitors, and thermal sensors. These features protect against data corruption, unexpected shutdowns, and overheating, preserving data integrity and system stability.

SMART Monitoring and Predictive Failure Analysis

Self-Monitoring, Analysis and Reporting Technology (SMART) attributes provide real-time insights into drive health, wear levels, and error rates. Dell OpenManage integration enables predictive failure analysis, allowing IT teams to proactively replace drives before failure, minimizing downtime and data loss.

Use Cases

Virtual Desktop Infrastructure (VDI)

VDI environments benefit from the Dell 345-BEYR’s high read throughput and low latency. User profiles, application binaries, and OS images are frequently accessed, making read-intensive SSDs the optimal choice. The drive supports fast boot times, responsive user sessions, and efficient resource allocation across virtual machines.

Content Delivery Networks (CDNs)

CDNs require rapid access to static content such as images, videos, and web pages. The Dell 345-BEYR’s read-centric design ensures fast content delivery, reduced latency, and improved user satisfaction. Its scalability allows for deployment across edge servers and caching nodes, enhancing global content distribution.

Real-Time Analytics and AI Inference

For analytics platforms and AI inference engines, the Dell 345-BEYR provides consistent read performance and low latency. It accelerates data ingestion, model loading, and query execution, enabling faster insights and decision-making. Its high IOPS capability supports concurrent access from multiple compute nodes.

Compatibility and Integration with Dell Infrastructure
