Dell 345-BMDX 15.36TB NVMe 2.5Inch SSD

This high-performance Dell internal SSD adopts the E3.S 2.5-inch form factor, enabling dense deployment in modern rack-mount and blade servers while maintaining excellent airflow and thermal stability. The PCIe Gen5 x4 interface dramatically expands bandwidth compared to earlier generations, making this drive suitable for mission-critical enterprise data centers that require real-time responsiveness.

High-Performance File Storage and NAS Acceleration

Network Attached Storage (NAS) appliances and scale-out file systems (like those from Qumulo, VAST Data, or Dell's own Power Scale) are increasingly adopting NVMe-oF (NVMe over Fabrics) to provide file services at local SSD speeds. The drives within these nodes benefit immensely from the density of E3.S and the performance of Gen5. A single storage node can deliver tens of GB/s of throughput, making it perfect for rendering farms, genomic sequencing, and financial modeling workloads

15.36TB Storage Capacity

With a massive 15.36TB of usable capacity, the Dell 345-BMDX SSD delivers enough space to support large databases, containerized applications, virtual machines, and big data repositories without compromising speed. This allows organizations to consolidate more data into fewer drives, simplifying storage management while boosting overall system performance.

PCIe Gen5 Performance Advantage

The 345-BMDX PCIe Gen5 interface delivers a dramatic leap in data throughput compared to PCIe Gen4 and Gen3 SSDs. This Dell NVMe drive uses a four-lane PCIe 5.0 connection, enabling data to move between the drive and CPU with extraordinary efficiency. As a result, applications that rely on high-speed storage see noticeable

Interface & Protocol: PCI Express 5.0 x4 NVMe

PCIe Gen5 doubles the bandwidth per lane compared to the previous Generation 4.0, delivering up to ~32 GT/s (Giga Transfers per second). With a four-lane (x4) interface, this provides a theoretical bandwidth ceiling of nearly 16 GB/s. This raw interface speed is fully harnessed by the NVMe protocol, which operates with extreme low latency and high queue depths, eliminating the bottlenecks inherent in the older AHCI protocol used by SATA drives. For applications involving massive datasets, such as AI training sets or data warehousing, this bandwidth is crucial for minimizing load times and accelerating data pipelines.

Form Factor: E3.S 2.5-inch (7.5mm thickness)

The 345-BMDX E3.S form factor maintains the familiar 2.5-inch drive width but adopts a connector (SNIA SFF-TA-1032) and slot-based installation that is distinct from U.2. The "2.5-inch" designation here refers to the drive's width, while its height (7.5mm) is a key attribute of the E3.S "S1" profile. This slim design allows for remarkable density; servers can now be configured with 10, 16, or even more drives in a single 1U chassis. This density is a game-changer for software-defined storage (SDS), hyper-converged infrastructure (HCI), and cloud service providers looking to maximize petabyte-per-rack-unit figures.

The Dell 345-BMDX is designed for next-generation Dell PowerEdge servers that feature PCIe Gen5 host bus adapters (HBAs) or direct motherboard support for E3.S drive bays. It is crucial to verify that your specific server model (e.g., PowerEdge R760, R760xa, XR7620) supports both the E3.S form factor and PCIe Gen5 speeds. The drive will typically be managed by the system's BIOS/UEFI and can be configured through the integrated Dell Remote Access Controller (iDRAC) for RAID or HBA modes.

Reliability

Enterprise storage must be reliable, and the Dell 345-BMDX NVMe SSD delivers with built-in data loss protection and a high mean time between failures. These features safeguard business-critical data during unexpected power events or system interruptions
