CY E1.S to U.2 SFF-8639 Adapter 9.5 15 25mm

SKU CH-CCD4-2S5XP

Converts E1.S EDSFF SSDs of 9.5, 15 or 25 mm thickness to a U.2 SFF-8639 PCIe 4.0 x4 interface for server and IoT use

  • Connects E1.S SSD to U.2 SFF-8639 host interface
  • Supports 9.5mm 15mm 25mm SSD thickness with heatsink
  • PCI Express 4.0 compliant for NVMe operation
  • Driverless installation works with current operating systems
  • Enables EDSFF E1.S drive use in IoT data center server

E1.S to U.2 Adapter for Data Centre SSDs

This adapter connects an EDSFF E1.S NVMe SSD to an internal U.2 SFF-8639 PCIe 4.0 x4 interface. It accepts drive thicknesses of 9.5mm, 15mm and 25mm, including models with integrated heatsinks. The converter requires no driver installation and works with current operating systems supporting PCIe NVMe storage.

Suited for Server and IoT Integration

Engineers upgrading dense server platforms or IoT appliances can install E1.S media into existing U.2 backplanes. The board is not designed for consumer desktops lacking a U.2 SFF-8639 connector or for builds that need M.2 or E3.S form-factor support.

PCIe 4.0 x4 Electrical Interface

The adapter is compliant with the PCI Express 4.0 specification across four lanes, delivering the full bandwidth available to the attached E1.S SSD. This electrical interface determines whether the host system can utilise the drive at its rated performance.

Questions about this item

What SSD thickness does the adapter accept?

The adapter fits E1.S SSDs that are 9.5 mm, 15 mm or 25 mm thick, including models with integrated heatsinks such as the PM9A3, PM9D3 and P5801X.

Which host interface does the adapter plug into?

It installs internally into a U.2 SFF-8639 PCIe 4x slot on the motherboard or backplane.

Does the adapter need firmware updates or active cooling later?

No firmware updates are required; the adapter is passive and relies on the host system's airflow to cool the installed SSD.
