What are the best midrange arrays? - page 5

All in all, midrange array users are a satisfied bunch, but the winner of the Quality Award in this category might surprise some people.

About the survey

The Diogenes Labs–Storage magazine Quality Award for midrange arrays complements our Quality Award for Enterprise Arrays (click here).

The Quality Awards identify and recognize products that have proven their quality and reliability in actual use. It's important to note that the awards aren't based on the subjective opinion of a few individuals, but are derived from a survey of qualified Storage readers that assesses products in five main categories: sales-force competence, product features, initial quality, reliability and technical support. Our methodology incorporates statistically valid polling that eliminates market share as a factor. Indeed, our objective is to identify the most reliable product on the market regardless of vendor name, reputation or size. Products were rated on a 1.0-to-8.0 scale, where 8.0 is the most favorable possible score.

The midrange array survey was completed by 339 respondents. Respondents were allowed to evaluate more than one array if they indicated a qualification to do so. Thirty-six percent of midrange respondents evaluated only one system vs. 26% in our earlier enterprise array survey. The study's margin of error is +6% with a 95% confidence factor.
