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.
• Solidigm™ creates drives in a few EDSFF types:
  • E1.L
    • Stands for "EDSFF 1U Long". Meant to maximize capacity.
    • Tall enough to fit in a 1U server standing up. They are about 320mm long, their thickness varies
  • E1.S
