Description

The 15.36TB NVMe Gen5 SSD in the EDSFF E3.S EC1 form factor is a hot-plug, read intensive drive built on the Samsung PM9D3a and designed for HPE Gen11 and Gen12 servers. It pairs a PCIe Gen5 interface with TLC NAND and SPDM support for device authentication, making it well suited to read-heavy workloads in dense server deployments.

Rated for 1.00 DWPD with maximum sequential throughput of 11,981 MiB/s read and 6,577 MiB/s write, this single-port drive delivers high capacity and fast random read performance. The E3.S design supports high-density storage layouts in current-generation HPE servers.

Features

- EDSFF E3.S design for dense Gen11 and Gen12 server storage
- PCIe Gen5 NVMe performance for read-heavy workloads
- SPDM support for device authentication
- Hot-pluggable for tool-free serviceability
- Read intensive TLC NAND with 1.00 DWPD endurance
- High random read performance with up to 1,296,764 IOPS at Q256
