“the medium is silica crystal, similar to optical cable, it’s highly durable. It’s also capacious: The technology can store up to 360 TB of data on a 5-inch glass platter.”

    How hf can you have 5D space within 3D space? This sounds like marketing bullshit.

    The 5D Memory Crystal stores data by using tiny voxels – 3D pixels – in fused silica glass, etched by femtosecond laser pulses. These voxels possess “birefringence,” meaning that their light refraction characteristics vary depending upon the polarization and direction of incoming light.

    That difference in light orientation and strength can be read in conjunction with the voxel’s location (x, y, z coordinates), allowing data to be encoded in five dimensional space.

    Oh, I get it now. It’s a five-dimensional mathematical space which is given by the three physical space dimensions plus the difference in light orientation and the difference the light strength.
