What performance specs does the Dell 345-BKBJ provide?

Dell 345-BKBJ offers sequential reads up to 14,000 MB/s, writes to 7,100 MB/s, random reads to 2,500,000 IOPS, and writes to 360,000 IOPS via PCIe Gen5 x4 NVMe. This enables wire-speed operation for read-intensive enterprise workloads like databases and analytics on PowerEdge servers.

What form factor and interface does it use?

E3.S 2.5-inch EDSFF form factor with PCIe Gen 5.0 x4 NVMe connector (E3.S 1T). Supports high-density deployments with superior cooling vs U.2, compatible with Dell trays for R650/R750 series.

Is it suitable for read-heavy workloads?

Yes, read-intensive TLC NAND excels in 10:1+ read/write ratios for web serving, logging, CDC, and analytics. Enterprise firmware ensures consistent QoS and endurance in data centers.

Which Dell servers support the 345-BKBJ?

Compatible with PowerEdge R250-R7725, T350-T560, C6520-C6525, HS5610-HS5620, XR2 via NVMe slots. Includes tray for hot-swap installation in Gen14-17 rack/tower servers.

How does PCIe Gen5 benefit over Gen4?

Doubles bandwidth to 128 GT/s per x4, enabling 2x throughput for I/O-bound apps. Reduces latency for real-time analytics and HPC, future-proofs against Gen6 transitions.

What is the endurance rating?

Read-intensive design with TLC flash provides high DWPD for reads (typically 0.3-1.0), optimized for workloads writing <10% of capacity daily. Enterprise-grade for 5+ year lifecycles.
