Fusion ioMEMORY SX350
Application Accelerator

The Fusion ioMemory SX350 is a cost-effective solution for accelerating read-intensive workloads. 



Get the Most out of Your Data Center

Fusion ioMemory PCIe application accelerators, with up to 6.4 terabytes1 of fast flash memory, accelerate the flow of data between servers and other assets. The end result? Data centers become optimized for utilization and performance, decreasing your TCO while boosting productivity.

A Spectrum of Applications

Fusion ioMemory PCIe application accelerators are deployed to improve virtualization, databases, business intelligence and real-time financial data processing as well as read-intensive workloads, such as web hosting, data mining, seismic data, content caching, 3D Animation, and CAD/CAM.


Fusion ioMemory PCIe application accelerators reduce your TCO in three fundamental ways:

  • reducing capital budgets for servers and other equipment
  • reducing operational expenses like energy and floor space
  • increasing the productivity of your employees and data center
Customers regularly experience data center consolidations of 3x or more1.


250,000 Deployments and Growing

Over 250,000 Fusion ioMemory PCIe application accelerators have been deployed by more than 7,000 customers including DataLogix, ObjectRocket by Rackspace, Pandora, Santa Monica City College, ServiceNow, TransUnion, the University of Michigan and University of Victoria, making Fusion ioMemory the proven choice for business-critical data centers.

SanDisk Case Study:

See how PlentyOfFish, one of the world’s largest dating sites, accelerated response time by 4x and scaled from 40 million users to 100 million with Fusion ioMemory technology.


1. 1TB = 1,000,000,000,000 bytes. Actual user capacity less.

2. Up to stated speed; performance may vary based on host device. 1GB = 1,000,000,000 bytes.

3. Approximations based on SanDisk internal metrics, that quantifies how much data can be written to a SSD in its lifespan expressed in terabytes written (TBW). For capacities of 128GB and above.

4. See product packaging materials for warranty terms and conditions.
