What type of storage device is ideal for a scientist concerned about electromagnetic interference?

The most suitable storage device for a scientist concerned about electromagnetic interference is the solid-state drive (SSD). SSDs are built using flash memory technology, which is not mechanically based like traditional hard disk drives (HDDs). This means they are inherently more resistant to electromagnetic interference because they do not rely on moving parts or magnetic disks that can be affected by electromagnetic fields.

In contrast, HDDs utilize magnetic storage and moving components that can be disrupted or damaged by strong electromagnetic fields. Therefore, they are not ideal in environments where such interference may occur. While SD cards and USB flash drives also use flash memory and possess similar resistance to electromagnetic interference, SSDs typically offer higher performance, durability, and storage capacity, making them a more preferred option in professional scientific settings.

This makes SSDs the best choice for storing critical data securely, even in environments with potential electromagnetic disturbances.
