Overview
Cloud services are revolutionizing how companies think of data storage by transitioning from fixed-cost IT infrastructure to variable cost models. As more business services move to the cloud to reap the benefits of the "pay as you go" model, the demands on cloud service providers to scale increase exponentially. Finding ways to maximize and streamline storage by running concurrent workloads across the storage infrastructure has become essential. Furthermore, cloud storage services must offer high availability and consistent I/O performance to be delivered 24/7, 365 days a year. Ultrastar DC SN620 NVMe SSDs help customers meet these rigorous requirements at a viable $/GB.¦SATA SSDs have long been used in data centers and cloud storage. But as capacity needs grow along with the necessity to access data with minimal latency, the adequacy of the interface bandwidth between the host and the drive comes under scrutiny. With no announced evolution of the SATA standard beyond SATA 3.x (6Gbps), the use of SATA SSDs in the cloud has reached performance limits. While capacity and bandwidth can be scaled by supplementing more SATA drives, they will come at the cost of increased floor space and lower PUE (Power Usage Effectiveness). The sprawling effect of SATA SSDs can be mitigated by the use of Ultrastar DC SN620 NVMe-compliant SSDs. By delivering 3x the bandwidth of enterprise SATA SSDs, Ultrastar DC SN620 SSDs can yield server consolidation benefits as much as 3:1.¦Utilizing the industry standard NVMe command protocol that lowers latency and improves bandwidth, Ultrastar DC SN620 PCIe SSDs enable a cost-effective transition to next-generation storage platforms. Ultrastar DC SN620 PCIe SSDs simplify large-scale deployment in the data center. This results in efficient workload utilization, a lower thermal profile compared to 25W PCIe SSDs and improved TCO. Ultrastar DC SN620 SSDs are powered by an innovative Guardian Technology Platform, a comprehensive suite of enterprise features comprised of FlashGuard, DataGuard, and EverGuard technologies. By leveraging Western Digital's history of providing world-class enterprise storage solutions, manufacturing excellence combined with commitment to reliability leadership, Ultrastar DC SN620 SSDs enable data center customers to innovate with minimal risk.¦Compliance and privacy requirements drive the need for increased data security. Ultrastar DC SN620 models with Instant Secure Erase (ISE) are not considered self-encrypting drives, but use behind-the-scenes encryption keys to expedite drive redeployment and retirement. Secure Erase (SE) models use industry-standard commands to securely erase without the use of encryption technology.
