HGST is showcasing a new architecture for solid-state drives (SSDs), which will allow the applications to deliver faster insights about the data intensive questions of tomorrow. The demonstration highlights the SSD performance levels which are achieved employing a combination of HGST’s new, latency-optimized interface protocols with next-generation non-volatile memory components.
The SSD makes use of the PCIe interface that provide three million random read IOs per second of 512 Bytes each when operating in a queued environment and a random read access latency of 1.5 microseconds (us) in non-queued settings, delivering results that cannot be achieved with existing SSD architectures and NAND Flash memories.
Steve Campbell, chief technology officer, HGST said, “The PCM SSD demonstration is a great example for how HGST sets the pace of the rapidly evolving storage industry. This technology is the result of several years of research and advanced development aimed at delivering new levels of acceleration for enterprise applications. The combination of HGST’s low-latency interface protocol and next-generation non-volatile memories delivers unprecedented performance, and creates exciting opportunities for new software and system architectures that HGST is exploring with our customers and industry partners.”
The SSD comes with 1GB of Phase Change Memory (PCM) components. In order to make complete use of this memory technology HGST has developed low-latency interface architecture. Apart from this HGST used its controller expertise to integrate the 45 nm 1Gb PCM chips to build a prototype full height, full length PCIe Gen 2×4 SSD card.
