Samsung patents stacked SSD design with interlocking plastic bases

Samsung has been granted a patent for a solid-state drive (SSD) that stacks two layers of circuit boards vertically to save space. The design uses matching bumps and notches on the bases of these boards to align them, while the top and bottom covers of the drive press down on specific points to hold the stack securely in place.

Why it mattersThis mechanical design allows for more compact storage drives, which is useful for slim laptops and portable devices where space is tight.
