There are no more doubts new that it is only a matter of time before all HDs get replaced by SSD. Current HD are limited by the mechanical factor, and not by its magnetic system that has proven to be reliable and efficient to offer large storage capacity units. In other words, the heads and discs of HDs are the limiting factors, for both transfer speed performance and access time. A new technology, known as Hard Rectangular Drive (HRD) and developed by DataSlide, might give HDs the way to compete with SSD on the long term.
If the magnetic storage principle is preserved, it is now rectangular and obviously does not spin anymore. Another layer containing several heads (64) is placed just above. By using a piezo-electric-driven oscillating rectangular record
