Removable NVMe SSD Storage: Technical Considerations

NVMe removability and the SHIPS platform

Developing reliable data storage

For over 30 years, CRU removable storage products and technology have been entrusted to secure sensitive data for military and government agencies and well-known organizations all around the world.

This paper will discuss the considerations the CRU engineering team has taken into account when developing robust, removable storage solutions for PCIe/NVMe SSDs. To develop a dependable removable solution for a high-speed

storage technology that wasn’t originally designed to be removable, the team had to consider: signal integrity, thermal issues, durability, and ruggedness.

Inside you’ll learn about:


Signal integrity

With high-speed signals employed to move data across multiple interconnects, maintaining the integrity of the data-carrying channels is crucial. 


Thermal issues

NVMe SSD controllers and NAND memory chips generate a large amount of heat, especially when constrained to enclosed spaces.


A standard, off-the-shelf NVMe SSD employs a connector designed for break/fix replacement, not the day-in/day-out removability required by data security usage or applications that rely on sneakernet for data transport.


When packaging NVMe storage into a module designed for non-office environments, design considerations for waterproofness, shock and vibration resistance, and operation over extreme temperatures need to be taken into account.
