Superior performance and economics for the cloud

Scale Faster with CloudSpeed

SanDisk understands hyperscale. CloudSpeed SATA SSDs combine the greater storage density and streaming bandwidth of flash for the price/performance needed to deliver video streaming, Big Data, SaaS, PaaS and other applications and services at scale.

Change Your Storage:
Change Your Data Center’s ROI

A drop-in replacement for HDDs, CloudSpeed SSDs can immediately improve the performance, reliability and energy consumption of your storage system, but that’s just the start. SSDs also mean greater utilization of servers, air conditioners and other data center assets while giving you more headroom to expand your business.


CloudSpeed Eco™ SSD

Designed for entry-level enterprise, hyperscale and cloud data center server and storage environments with read-intensive workloads.


CloudSpeed Ascend™ SSD

For read-intensive application workloads, such as file servers, Web-based applications, and virtual tape libraries (VTL). Along with SanDisk’s Guardian Technology platform and multi-level cell (MLC) NAND flash technology, they deliver all the features expected from an enterprise-class SSD—at a great value.


CloudSpeed Ultra™ SSD

For mixed-use application workloads such as Financial Transactions, E-Commerce and Email/Messaging. CloudSpeed SSDs use SanDisk’s Guardian Technology platform to increase endurance up to 5x4 higher than other multi-level cell (MLC) SSDs.

5x Higher Endurance

The most important feature is the Guardian Technology™ Platform which is a proprietary suite of enterprise features and endurance enhancement technologies allowing the CloudSpeed SSD to deliver 5x higher endurance4 than competing client MLC (Multi-Level Cell) SSDs.
