A user on the social network X under the pseudonym @dyd_Nao has showcased a storage device he created, which stands out dramatically from existing market offerings. This massive board, about the size of a plate, is designed to hold a mere 128 bytes of data (no error here – exactly 128 bytes).

Not only is the storage capacity minuscule, but it also relies on a rather antiquated technology. Magnetic core memory is used here, a technology that harkens back to computers from the 1950s to the 1970s. These core memory chips are famous for their non-volatile nature, yet they are limited by their low capacity, which largely explains the small size of this device. Despite its outdated nature, this experiment harks back to a time when such technology was cutting-edge. More recently, magnetic core memory has been primarily used for educational purposes and demonstrations to showcase the evolution in computing technology.

Another peculiar feature of this system is that while the memory itself is non-volatile, the data gets erased upon reading. Simply put, you can only read the data from this storage once. This quirk highlights the experiment’s nature – a throwback to a different era of computing rather than any practical application. This experiment serves as a stark contrast to modern storage technologies, such as SSDs (Solid State Drives) and NVMe (Non-Volatile Memory Express) drives, which offer vastly superior speed, capacity, and reliability.
