Economies of Scale Propel Cloud Storage
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 ser vice 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
customers meet these rigorous requirements at a viable $/GB.

Ultrastar DC SN620 SSDs Help Increase
Productivity and Lower TCO
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.
Highly Reliable Storage Innovation
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.
Available in the 2.5-inch small form factor with typical power consumption under 11W
and hot-swap capability, 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.
Options to Simplify Data Security
Compliance and privacy requirements drive the need for increased data security.
Ultrastar DC SN620 models with Instant Secure Erase (ISE) are not considered selfencrypting 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.
