![]() When it comes to accessing any data it’s stored, NVMe clocks in consistent sub millisecond (0.25-0.5ms) access. Compare this highway to Heaven to HDD, which has one queue and can do one only operation at a time. ![]() This can best be thought of like lanes on a highway: 64,000 lanes with as many cars in each one. Part of this speed is derived from the fact that NVMe is highly parallel with its functionality, processing 64,000 command across 64,000 queues. The first reason is right in the name: Flash offers faster access to serving data and is more consistent in its performance. Here lie the main reasons its time as your primary storage is over. The hole has been dug: Spinning disk is all but dead. Over six decades, applications have changed drastically, and so too should our storage layer. But while 60 years can be a lifetime for humans, it’s an eternity for technology. Meanwhile, hard drives (often called HDDs or spinning disks) are traditionally championed for their large capacity as well as their long and illustrious life, nearly 60 years in fact. ![]() But as this industry continues to evolve, a few key questions emerge: Are hard drives the new vinyl? And if so, are flash drives picking up the needle?įlash (specifically nonvolatile memory express or NVMe) boasts impressive speeds and is greener in a few senses, both as a newer technology and one that’s better for the environment. While some people are still scratching records, others are scratching their heads as they consider the future of a different sort of disk: their digital storage. The words “spinning disk” might conjure images of bicycles or DVDs or vinyl records: technologies that are all still functional but hardly at the forefront.
