The Dell 345-BKFN is a high-performance enterprise NVMe SSD designed for next-generation Dell PowerEdge servers (16G and 17G). Built on PCIe Gen 5.0 x4 technology with NVMe 1.4 protocol compliance, this drive delivers exceptional read-intensive performance with sequential read speeds up to 14,000 MB/s and random read IOPS up to 2,000,000. The 1.92TB capacity utilizes enterprise-grade TLC NAND flash memory with a sophisticated multi-channel ASIC controller managing wear leveling, bad block management, and error correction. The E3.S 2.5-inch form factor (7.5mm height) enables high-density storage configurations within PowerEdge chassis. With 3,504 TBW endurance rating and 2.5 million hour MTBF, it provides reliable performance for virtualization, containerized environments, AI/ML inference, real-time analytics, and large-scale transactional databases. The drive includes a Dell NV2RX tray for seamless installation.

Sub-millisecond latency for in-memory analytics, data warehousing, and business intelligence workloads with 2M read IOPS.
Fast model loading and inference data access for machine learning pipelines leveraging PCIe Gen 5.0 bandwidth.
Read-optimized performance for cached content distribution and search indexing with enterprise-grade endurance.
Low-latency storage tier for transactional databases and large-scale OLTP workloads with predictable performance.
The 345-BKFN delivers sequential read speeds up to 14,000 MB/s and sequential write speeds up to 3,000 MB/s. These speeds are enabled by the PCIe Gen 5.0 x4 interface providing 128 GT/s peak throughput. The read-intensive design prioritizes read performance for analytics and virtualization workloads.
The 345-BKFN is compatible with Dell PowerEdge 16G and 17G servers that support NVMe E3.S form factor drives. It includes a Dell NV2RX tray for seamless installation. Compatibility extends to systems like the R770 and R670 with appropriate NVMe drive bay configurations.
The 345-BKFN provides 3,504 terabytes written (TBW) endurance with 1 drive write per day (DWPD) over 5 years. Mean time between failures (MTBF) is rated at 2.5 million hours. These metrics reflect enterprise-grade reliability for mission-critical data center deployments.
The E3.S 2.5-inch form factor with 7.5mm height enables high-density storage configurations within PowerEdge chassis while accommodating the thermal and power demands of PCIe Gen 5.0 devices. This compact design maximizes storage capacity per rack unit compared to traditional U.2 drives.
The drive features enterprise-grade triple-level cell (TLC) 3D NAND flash memory managed by a high-performance multi-channel ASIC controller. The controller handles wear leveling, bad block management, garbage collection, and error correction to ensure consistent performance and data protection.
The 345-BKFN is optimized for read-intensive workloads where data is frequently accessed but written less often. Ideal use cases include content delivery, search indexing, analytics queries, virtualization, and AI/ML inference. Write speeds (3,000 MB/s) are lower than read speeds, reflecting this design philosophy.
