Скачать или смотреть Showdown: NVMe vs. SATA SSDs with Western Digital

When NVMe drives first came out, we knew the performance would be superior, but questioned when they would be cost-comparable to SATA SSDs. Due to their cost initially, NVMe drives were mainly used for enterprise applications. It didn’t take very long, however, for NVMe drives to become cheaper than SATA/SAS SSDs in terms of dollars-per-IOPS. Now, we are starting to reach the point where they are not that much more expensive than SATA/SAS SSDs on a capacity basis.

Through testing Western Digital's Ultrastar SN640, we found that the data clearly shows NVMe is the path forward when it comes to providing responsive performance to the diverse set of workloads in the data center. Not only will NVMe drives increase the performance of current workloads, such as databases and virtualized workloads, but they position the data center for the more demanding next-gen workloads that are starting to appear, such as machine learning (ML) and artificial intelligence (AI), which require storage solutions with ultra-low latency and ultra-high bandwidth.

Western Digital—using its latest in-house controller, 96L flash, and firmware—has delivered a mainstream NVMe SSD which balances performance and power for a cost-effective solution to displace SATA once and for all. When viewed through the performance lens as illustrated above, there’s simply no reason to be using SATA SSDs for data storage.
