E3.S is a new form factor standard for NVMe™ SSDs in Cloud and enterprise data centers, especially targeting PCIe® 5.0 and beyond. The E3.S will contribute to the design and development of next generation systems, such as cloud, hyper-converged and general-purpose servers and All Flash Array (AFA) systems in cloud and enterprise data centers.


The E3.S specification allows for size, power and capacity options, all with a common connector. Designed for future PCIe generations that offer higher power budgets, EDSFF E3.S delivers improved performance, cooling and flexibility over other form factors.


Kioxia’s E3.S engineering samples, based on Kioxia’s CM6 Series PCIe 4.0 NVMe 1.4 SSD in a 2.5-inch form factor, demonstrated approximatery 35% greater performance with the same controller and BiCS FLASH™ 3D TLC flash memory in the EDSFF E3.S form factor with x4 lanes and 28W (+40%) of power.


EDSFF E3.S benefits include:
- Higher density of flash storage for more efficient use of power, storage footprint and system rack deployments
- Supports PCIe 5.0 and beyond through improved signal integrity
- Better cooling and thermal characteristics
- Performance and benefits beyond the 2.5-inch form factor version
- Drive status can be shown by LED indicators
- Supports x8 PCIe lane configurations
