Dell 2TB NVMe U.2 PCIe G3 x4 2.5" SSD Intel DC P4510 SSDPE2KX020T8T 09H31J 9H31J

The Dell 2TB NVMe U.2 PCIe SSD (09H31J) is an enterprise-class solid-state drive based on the Intel DC P4510 series, designed for high-performance data center workloads such as virtualization, cloud infrastructure, and database environments. Built with 64-layer 3D TLC NAND and a PCIe Gen3 x4 NVMe interface, this drive delivers high throughput, low latency, and strong endurance for demanding enterprise storage environments.

• Capacity: 2TB

• Manufacturer: Intel (DC P4510 Series)

• Dell Part Number: 09H31J / 9H31J

• Model Number: SSDPE2KX020T8T

• Form Factor: 2.5-inch Small Form Factor (SFF) – 15mm height

• Interface: PCIe 3.0 x4 NVMe (NVMe 1.2 compliant)

• Connector: U.2 (SFF-8639)

• NAND Flash: 64-Layer 3D TLC

• MTBF: 2 Million Hours

• Shock Resistance: 1000 G (0.5 ms)

• Sequential Read Speed: Up to 3,200 MB/s

• Sequential Write Speed: Up to 3,000 MB/s (some Dell variants up to ~1,600 MB/s)

• Random Read (4K): Up to 637,000 IOPS

• Random Write (4K): Up to 139,000 IOPS

• Read Latency: ~10 µs

• Write Latency: ~18 µs

These performance characteristics make the drive suitable for virtualization clusters, high-performance databases, and high-speed enterprise storage arrays.

• Endurance Rating: Up to 1 Drive Write Per Day (DWPD) for 5 years

• Power Loss Protection: Enhanced power-loss data protection with onboard capacitors

• Data Integrity: Enterprise-grade firmware and ECC error protection

The integrated power-loss protection safeguards in-flight data during unexpected power interruptions.

• Active Power: Up to ~16 Watts

• Idle Power: Approximately 5 Watts

• Form Factor: 2.5" U.2 NVMe SSD

• Height: 15 mm

• Weight: ~139 g

Because this is a 15mm enterprise drive, it requires a compatible 2.5" NVMe drive bay and will not fit in thinner laptop or consumer bays.

The Dell-branded firmware (09H31J) is validated for many Dell PowerEdge servers, particularly those supporting NVMe backplanes.

14th Generation PowerEdge (Recommended)

• Dell PowerEdge R640

• Dell PowerEdge R740

• Dell PowerEdge R740xd

• Dell PowerEdge R940

• Dell PowerEdge T440

• Dell PowerEdge T640

Modular / Blade Platforms

• Dell PowerEdge FX2

• Dell PowerEdge FD332

15th Generation Example

• Dell PowerEdge R750xs

13th Generation (Optional NVMe configuration required)

• Dell PowerEdge R630

• Dell PowerEdge R730

These systems require NVMe-enabled backplanes and PCIe extender cables when configured for U.2 NVMe drives.

Because the drive is based on the Intel DC P4510 platform, it can also be used in other enterprise servers with NVMe support:

• HPE ProLiant: NVMe-enabled Gen10 / Gen11 systems such as DL360 and DL380 with Express Bay kits

• Lenovo ThinkSystem: NVMe systems such as SR630 or SR650

• Supermicro Servers: Any system with NVMe-enabled backplanes

Non-Dell systems may function normally but may not display full Dell-specific telemetry through system management tools.

This U.2 NVMe drive can also be used in workstations or desktop systems with the proper adapter:

• Requires a U.2 to PCIe adapter card or compatible NVMe backplane

• Supported operating systems include:

  • Microsoft Windows Server 2016 / 2019 / 2022

  • VMware ESXi 6.5 U2 and newer

  • Red Hat Enterprise Linux 7.6+

  • Ubuntu 18.04.2+

To use this SSD properly, the system must meet these requirements:

• NVMe-enabled backplane (SATA/SAS-only bays will not detect the drive)

• U.2 / SFF-8639 connector support

• 15mm drive bay clearance

This enterprise SSD may also appear under the following part numbers:

• SSDPE2KX020T8T

• 09H31J

• 9H31J

These identifiers may represent Dell OEM firmware versions or Intel manufacturing model numbers, but they refer to the same 2TB Intel DC P4510 U.2 NVMe enterprise SSD platform when specifications match.
