Overview

EDSFF stands for "Enterprise and Datacenter Standard Form Factor" and is not only for SSDs.
These are purposely built for integrated circuits and move away from the form factors used by HDDs and early SSD integration or adoption.
All EDSFF (as of this writing) use the same connector, interface and protocol.
- This means any EDSFF can be switched with another, only limited by the physical dimensions of the unit(s) and system.
