What servers is the Dell 400-BKGL compatible with?

Compatible with Dell PowerEdge R-series Gen14+ (R440, R640, R740, R740XD, R750), XE-series (XE2420, XE8640), HS-series Gen16, and PowerVault MD2424 via NVMe U.2 2.5in bays. Requires NVMe-capable backplane and latest BIOS/firmware.

What is the endurance rating of this SSD?

Rated for 1 DWPD Read Intensive over 5 years, equating to ~7PB total bytes written. Optimized for read-heavy workloads like databases and caching with 70:30+ read/write ratio using enterprise 3D TLC NAND and advanced wear leveling.

Does this SSD include a carrier/tray?

Yes, ships as SSD W-TRAY kit with Dell-certified U.2 carrier for hot-swap installation in compatible PowerEdge servers. Supports iDRAC monitoring and OpenManage integration for health telemetry and predictive failure analysis.

What interface speed does it support?

PCIe Gen4 x4 NVMe at 32Gbps full duplex with U.2 connector. Backward compatible with PCIe Gen3 at 16Gbps. Delivers high sequential throughput and IOPS for NVMe-optimized applications in Gen14/15/16 PowerEdge platforms.

Is this drive suitable for write-heavy workloads?

Designed for Read Intensive use (1 DWPD), best for read-dominated workloads like web servers, VDI, and analytics. For mixed/heavy write, select Dell Mixed Use (3-5 DWPD) or Write Intensive SSDs from Express Flash NVMe portfolio.

What form factor and dimensions?

Standard 2.5-inch U.2 (15mm z-height) at 100.50 x 69.85 x 14.80mm. Fits all Dell PowerEdge 2.5in NVMe drive bays with tray. Weighs 0.4 lb for high-density configurations without airflow obstruction.
