[Hardrive]( Data in a Flash, Part I: the Evolution of Disk Storage and an Introduction to NVMe Petros Koutoupis - April 29, 2019 NVMe drives have paved the way for computing at stellar speeds, but the technology didn't suddenly appear overnight. It was through an evolutionary process that we now rely on the very performant SSD for our primary storage tier. Solid State Drives (SSDs) have taken the computer industry by storm in recent years. The technology is impressive with its high-speed capabilities. It promises low-latency access to sometimes critical data while increasing overall performance, at least when compared to what is now becoming the legacy Hard Disk Drive (HDD). With each passing year, SSD market shares continue to climb, replacing the HDD in many sectors. The effects of this are seen in personal, mobile and server computing. IBM first unleashed the HDD into the computing world in 1956. By the 1960s, the HDD became the dominant secondary storage device for general-purpose computers (emphasis on secondary storage device, memory being the first). Capacity and performance were the primary characteristics defining the HDD. In many ways, those characteristics continue to define the technology—although, not in the most positive ways (more details on that shortly).
