Ultrastar DC SN630

Economies of Scale Propel Cloud Storage
Next generation cloud data centers are now deploying NVMe SSD storage as a core component, replacing the slower legacy SATA interface. The Ultastar DC SN630 NVMe SSD is built on Hitachi’s in-house controller and firmware technology and utilizes our own 64-layer BiCS3 3D NAND, which allows Hitachi to tightly control all design aspects and consistently deliver low latency and high performance. This essential NVMe offering provides twice the maximum capacity per slot and more capacity choices than our prior generation, up to 7.68TB.

Cloud services are revolutionizing how companies think about data storage by transitioning from fixed-cost UT 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 SN630 NVMe SSDs help customers meet these rigorous requirements at a viable $/GB.

Ultrastar DC SN630 SSDs Increase Productivity and Lower TCO
SATA SSDs have long been used in data centers and cloud storage. But as capacity needs grow, along wit the necessity to access data with minimal latency, the adequacy of the interface bandwidth between the host and the drive comes under scrutiny. The SATA (6Gb/s) interface constrains performance of most SSDs and introduces latency compared to NVMe SSDs. Utilizing higher capacity points with fast, low latency NVMe allows data center architects to reduce the number of servers deployed while still handling more users and providing more services per server. Server reduction, in turn, reduces the number of “per-core” software licensing fees required resulting in even lower TCO.

Highly Reliable Storage Innovation
Utilizing the industry standard NVMe command protocol that lowers latency and improves bandwidth, Ultrastar DC SN630 SSDs enable a cost-effective transition to next-generation storage platforms.

Available in the 2.5-inch U.2 small form factor with a slim 7mm profile, typical power consumption under 10.75W, and hot-swap capability, Ultrastar DC SN630 NVMe 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 SN630 SSDs protect your data by providing data protection, proprietary wear levelling algorithms, and power loss protection required in a demanding enterprise environment. By leveraging Hitachi’s history of providing world class enterprise storage solutions, manufacturing excellence, and commitment to reliability leadership, Ultrastar DC SN630 SSDs enable data center customers to innovate with minimal risk, backed with a 5-year limited warranty.

Options to Simplify Data Security
Compliance and privacy requirements drive the need for increased data security. Ultrastar DC SN630 models with Instant Secure Erase (ISE) provide peace of mind by using behind-the-scenes encryption keys to expedite drive redeployment and retirement.

Secure Firmware downloads with RSA authentication ensure that the drive runs authentic Hitachi firmware only.
