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 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 oer high availability and consistent I/O performance to be delivered
24/7, 365 days a year. The Skyhawk™ PCIe SSD helps customers meet these rigorous
requirements at a viable $/GB.

Skyhawk 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
Eectiveness). The sprawling eect of SATA SSDs can be mitigated by the use of
Skyhawk NVMe-compliant SSDs. By delivering 3x the bandwidth of enterprise SATA
SSDs*, Skyhawk 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, Skyhawk PCIe SSDs enable a cost-eective transition to next­generation storage platforms.

Available in the 2.5-inch small form factor with typical power consumption under
11W and hot-swap capability, Skyhawk PCIe SSDs simplify large-scale deployment in
the data center. This results in ecient workload utilization, a lower thermal profile
compared to 25W PCIe SSDs and improved TCO.

Skyhawk 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, the SanDisk-branded Skyhawk PCIe SSD
enables data center customers to innovate with minimal risk.

One gigabyte (GB) is equal to 1,000MB (one billion bytes) and one terabyte (TB) is equal to 1,000GB (one trillion bytes) when referring to solid-state capacity.

Accessible capacity will vary from the stated capacity due to formatting and partitioning of the drive, the computer’s operating system, and other factors.
