ssd 500gb HDD hard drives also support NVMe 2.0 standard: bring ZNS partition namespace and other functions
external hard disk SSD OEM SSD500GB initially SSD hard drives use the SATA interface protocol of HDD hard drives. In 2011 ssd 500gb, Intel and the industry jointly introduced the NVMe standardssd 500gb, more powerful. Now SSDs have fully switched to the NVMe protocol.
Last week, the latest NVMe 2.0 standard was announced, a massive upgrade of the standard from 9 years ago, and bringing new features such as ZNS partition namespace, KV command set, Endurance Group Management, multi-controller update definition, shutdown enhancement and so on.
NVMe 2.0 is obviously prepared for the new generation of SSD drives, but the difference this time is that it also supports HDD drives, which is a bit interesting. Earlier SSD drives used the HDD hard disk protocol. Today, ten years later, the SSD protocol has begun to dig the corner of HDD mechanical hard disks, and the SATA protocol may be eliminated in the future.
At the current speed of 200MB/s mechanical hard disk, SATA 6Gbps 600MB/s speed is enough, but the new generation of mechanical hard disk also began to have a freak like Seagate Mach.2, which achieved a speed of 524MB/s by using dual robotic arms, gradually approaching the upper limit of SATA, and even surpassing many TLC/QLC flash SSD hard disks.
hard drives like Mach.2 and HAMR thermal-magnetic assisted recording technology will have breakthroughs in the performance of HDD hard drives in the future. It is necessary to follow the technical standards of SSDs, especially in the high-performance data center market.
