Increase flash capacity in PCIe NVMe server platforms with a 15.36 TB KIOXIA CM9 enterprise SSD in the E3.S form factor. The drive is specified with a PCIe 5.0 interface and NVMe protocol support, providing a modern storage connection for servers, storage appliances, and dense flash deployments built around E3.S bays. Its 1 DWPD endurance class targets capacity-oriented enterprise workloads that still require regular daily writes. The E3.S form factor is a key fit requirement for this drive. It is intended for infrastructure using E3.S NVMe storage bays rather than legacy 2.5-inch SATA or SAS bays. PCIe NVMe connectivity attaches storage directly through the host platform’s PCIe fabric, so system compatibility depends on an available E3.S PCIe NVMe slot and platform support for the drive’s interface generation. SDF4881GEB01T represents the 15.36 TB, 1 DWPD configuration within the CM9 enterprise SSD family. That combination favors high usable capacity per drive position while retaining an endurance rating suited to daily write workloads. The supplied configuration also carries the SIE designation. Select it when an E3.S PCIe NVMe deployment requires this exact capacity, endurance class, and security feature designation.
