You read that right. NVMe protocols that enable very fast SSD read and write speeds will soon support "rotating disks," that is, hard disks, hard disks. This won’t make your hard drive any faster (this is still limited by the speed at which you can operate the arm inside the drive), but it does mean that there are fewer reasons for SATA to be maintained in the future. .
The hard drive bracket comes next to the new one NVMe 2.0 specification (thanks, Anandtech), which includes lots of upgrades for more efficient use and storage via an SSD drive along with turntables. NVMe, or non-volatile Memory Express, is the bridge between an SSD and its host, often a PC for us. It is the most popular interface of modern SSDs found in gaming computers and is essentially a way for your SSD to take advantage of the speeds offered by the high-bandwidth PCIe bus.
Now you may be wondering why make it available to a hard drive that can't hold a candle at PCIe SSD speed? Really, we won’t see hard drives suddenly abandoning SATA III connectors for some messy devices in the M.2 slots, it’s more for enterprise-level configurations that pursue simplicity and uniformity.
According to the NVM Express website, NVMe points to a "life after SATA", where one day NVMe completely replaces the aging standard. Turntables are no longer a storage option for gaming machines, but they will go nowhere for cheap, high-capacity storage. A modern alternative to the SATA standard, even for hard drives, is a prerequisite if NVMe expects to replace it.
And HD drives are still faster, even by current SSD standards.
"Since SATA 3.0 was ratified many years ago, CPU and NAND flash memory technology has advanced at an aggressive pace and the SATA interface has become a bottleneck," says a publication in the blog on the NVMe website.
"While SATA was great for adopting data center SSDs, data center PCIe 4.0 NVMe SSDs offer significantly higher performance, lower latency, and alleviate bottlenecks between CPU and CPU. "Flash storage. As future generations of performance-based applications require organizations to rethink their business and data center strategies, SATA will become a thing of the past."
The rest of the newly released NVMe 2.0 specs are largely owned by SSDs directly, and some may even affect gaming favorites. Most exciting is a new zone storage device interface that allows the SSD and host to jointly decide on the location of data for better performance and capacity.
All features included with the NVMe 2.0 specification will also maintain compatibility with previous generations, so don’t worry about being left in the dust if you’ve only upgraded to one of the best NVMe SSDs.
