What performance specs does the Dell 345-BMJS SSD provide?

The Dell 345-BMJS offers up to 2,500,000 random read IOPS, 360,000 random write IOPS, 14,000 MB/s sequential read, and 7,100 MB/s sequential write via PCIe Gen5 x4. This read-intensive design excels in workloads prioritizing rapid data retrieval with optimized caching and firmware for Dell PowerEdge servers.

Which Dell servers support the 345-BMJS E3.S SSD?

Compatible with PowerEdge R660/R670/R760/R770/R860/R960 series, XE7745/XE9680/XR7620, and others featuring PCIe Gen5 E3.S bays. Verify via iDRAC or server specs for direct motherboard or HBA support; hot-swap installation in front-accessible trays.

What is the endurance rating of the 345-BMJS?

Rated at 1 DWPD for 5 years with 28,032 TBW total endurance and 2,500,000 hours MTBF. Includes data loss protection, making it suitable for read-intensive enterprise use without frequent writes.

How does E3.S form factor benefit deployments?

E3.S (2.5-inch width, 7.5mm height, SNIA SFF-TA-1032 connector) enables higher density, better airflow, and PCIe Gen5 power envelopes vs. U.2 drives. Ideal for next-gen PowerEdge chassis reducing drive count and rack complexity.

Is the 345-BMJS optimized for read-intensive workloads?

Yes, firmware prioritizes read performance with read-ahead algorithms and command scheduling for consistent low-latency access. Perfect for analytics, virtualization, and databases where reads dominate over writes.

What NAND type and interface does it use?

TLC NAND flash over NVMe protocol on PCIe Gen5.0 x4 with E3.S 1T connector. Supports high-capacity 15.36TB in compact form for modern data center scaling.
