Lower Storage Costs and Increase Efficiency with the Superior Data Reduction Capabilities of Dell PowerStore

In an era of rapid data growth, simply adding more hardware is not a sustainable strategy. The key to a modern data center is efficiency; maximizing every terabyte to reduce costs, power consumption, and physical footprint. But not all data reduction technologies are created equal.

We commissioned Principled Technologies to run a head-to-head test between Dell PowerStore and five major competitors. The results were clear: Dell PowerStore achieved a 5.4:1 data reduction ratio, outperforming the field and proving to be up to 3.1x more efficient than other leading solutions.

Key Highlights:

Superior Efficiency
: Dell PowerStore delivered the highest data reduction ratio among all six solutions tested.

3.1x Advantage: Performance testing showed PowerStore is up to 3.1x more efficient than specific competing storage arrays.

5.4:1 Reduction Ratio: Achieved a verified 5.4:1 ratio on a standardized compression and deduplication data set.

Significant Space Savings: PowerStore helps organizations use up to 68% less physical storage space compared to HCI competitors.

Industry-Leading Guarantee: Dell asserts a 5:1 data reduction ratio guarantee for new PowerStore models through the Future-Proof Program.

Ease of Use: Ranked #1 in ease of use by customers, simplifying day-to-day IT operations.

Lifecycle Extension: Integrated support via Dell ProSupport™ ensures long-term infrastructure viability.

Built-in Protection: Features integrated data protection with Storage Direct Protection for enhanced resilience.

Cost Optimization: Drastically reduces the total cost of ownership by maximizing the capacity of every drive.

Verified Science: The results are backed by the rigorous "Science behind the report" methodology from Principled Technologies.

Competitive Benchmarking: Detailed comparison against "Storage Vendors C, L, A" and "HCI Vendors G and U."
