Icy Dock just unveiled the CP155 adapter, a tough little device that turns a 5.9 mm or 8.01 mm E1.S NVMe SSD into a standard 9.5 mm E1.S drive. It’s designed to match the connector spots, size, and mounting points of 9.5 mm E1.S modules perfectly, so it works seamlessly with existing backplanes, trays, and tool-less drive carriers. With its sturdy all-metal build and high-quality thermal pads, the CP155 not only boosts compatibility but also improves heat dissipation—making it a great choice for system builders, data center pros, and OEMs who want to standardize SSD sizes across different setups.
The CP155 fills the gap between slimmer E1.S SSDs (5.9 mm and 8.01 mm) and the common 9.5 mm slots. By matching the height, screw holes, and connector alignment, it ensures a snug, reliable fit in 9.5 mm-compatible trays, caddies, and hot-swap server systems—no custom tweaks needed!
LED Window for Easy Monitoring
The CP155 has a handy cutout at the back that reveals the LED indicators on 5.9 mm and 8.01 mm E1.S SSDs, lining up with the standard 9.5 mm LED window. This lets you check the SSD’s power and activity status without taking the adapter off, making installation or maintenance a breeze.
Smart Cooling with a Metal Design

The CP155 features an aluminum top and a SECC steel bottom, acting as a solid heatsink to handle extra heat. It comes with both thin and thick thermal pads to keep the SSD in close contact with the case, lowering operating temps and extending SSD life in tight or warm environments.
