EDSFF E1 Form Factor
KIOXIA Corporation provides next-generation PCIe® 4.0 data center NVMe™ SSDs with its XD6 and XD7P Series, which are designed to the Open Compute Project® (OCP) Datacenter NVMe™ SSD specification and available in E1.S form factors. There are a number of key reasons why these new EDSFF E1.S SSDs can enable a data center server architecture to adapt to changes, but the top five supported by KIOXIA include:
E1 - Hyperscale Servers and Storage
|E1.S 5.9 mm||31.5||111.49||5.9||12|
|E1.S 8 mm with heat spreader||8.01||16|
|E1.S 9.5 mm with symmetric enclosure||33.75||118.75||9.5||20|
|E1.S 15 mm with asymmetric heatsink||15||25|
|E1.S 25 mm with asymmetric heatsink||25|
|E1.L 9.5 mm with symmetric enclosure||38.4||318.75||9.5||25|
|E1.L 18 mm with symmetric heatsink||18||40|
EDSFF E1.S Use Cases
