Power Consumption
Physical Specifications
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.
Dell PowerEdge Server Compatibility
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
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.
Cross-Brand Server Compatibility
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.
Workstation & Desktop Compatibility
This U.2 NVMe drive can also be used in workstations or desktop systems with the proper adapter:
