Hybrid Solid State Disk

The exponential growth of vast quantities of data in digital age is outpacing the development of system infrastructure needed to support data-driven 21st century applications. One of the major challenges of today’s Industry is to provide uniform high-speed memory access to multi-terabyte data structures for 21st century data intensive applications.The current facts that give rise to the need of a new architecture for the hard disk are:

  • Current Hard Disk Drives (HDD) are electro - mechanical in nature and therefore extremely slow and consume large amount of energy.
  • Increasing performance disparity between the processor and memory hierarchy has been widening too fast giving rise to performance gap.
  • Total carbon footprint, due to power consumption in the ICT, is becoming very large; for instance, the carbon footprint due to ICT is approximately equal to that of the UK aircraft industry.

High performance and energy efficient computing systems can be designed to address these issues if:

  • Access time to data on secondary storage is decreased, resulting in improved CPU utilization (preferably no idle time for CPU)
  • Energy efficiency is improved by minimizing power consumption of storage systems.
