6Gb/s SATA Data Center SSD
CloudSpeed Ultra™ Gen. II SATA SSD
Data Center Grade Flash Storage
Elastic Infrastructure Powers Cloud and Software-Defined Storage
• Capacity offerings: 1.6TB, 800GB and
Elastic infrastructure powers databases, mission-critical applications, mobile apps,
collaboration, and IT infrastructure. Whether delivered by cloud service providers
or cloud-like software-defined storage solutions, elastic infrastructure needs to
leverage storage performance to enable the type of data services that help run
enterprises or enable personal productivity and leisure time.
• Optimized for mixed-use, latency sensitive write operations
• 1.6TB version capable of 32,000 4K
write IOPS; fewer servers to deliver
I/O performance
• QoS – average write latency at 56μ
• Low power consumption compared
to traditional HDDs
• Data loss protection with power
failure protection
• Includes the innovative Guardian
Technology™ Platform for improved
flash endurance and data integrity/
• MTBF = 2 Million hours
• Cryptographically signed firmware
• Works within existing infrastructure –
6Gb/s SATA interface
Specialized for the following
• Demanding QoS, Latency-Sensitive
Applications and Databases
• IaaS, PaaS, and SaaS infrastructure
• NoSQL Performance Acceleration
• DBaaS, MySQL, PostgreSQL
Transaction Processing
• OpenStack
• Software-Defined Storage
• E-Commerce, micropayments
Storage performance – intensive I/O operations at low response times – is key
to enabling transaction processing that is the basis of cloud-based e-commerce,
micropayments, in-app purchases, and on-premises software-defined storage to run
enterprise latency-sensitive workloads.
Storage Price/Performance is Necessary for Cloud Economics
In order for XaaS cloud business models and software-defined storage solutions
to flourish, price/performance must be attainable. Though many varieties of
proprietary, high-performing storage solutions already exist, cloud service providers
and software-defined storage solutions, e.g., hyperconverged infrastructure,
architect their systems to maximize the utility of standard, commodity hardware.
The ability to achieve maximum performance, while achieving price/performance
based on commodity hardware is crucial for cloud delivery on an elastic
CloudSpeed Ultra Gen. II for Cloud Economics
To help enable elastic infrastructure for the cloud era, SanDisk® offers a SATA SSD
with price/performance capability to enable cloud and software-defined storage to
provide elastic performance for latency-sensitive workloads.
CloudSpeed Ultra Gen. II SATA SSD – up to 1.6TB capacity - breaks the sub$1 per gigabyte barrier for performance-optimized SATA SSDs. SanDisk price/
performance value is achieved by leveraging CloudSpeed Ultra performance that
enables cloud storage and compute density without the sacrifice of a low latency
QoS or write operations.
For use in mixed-use workload environments with write operations, CloudSpeed
Ultra performs 32,000 4K write IOPS with an average write latency of 56
CloudSpeed provides for an overall lower total cost of ownership (TCO) based on
the ability to achieve storage and compute density for elastic cloud computing.
