All-Flash Storage Arrays: Buyer’s Guide and Reviews

Bar length
The total ranking of a product, represented by the bar length, is based on a weighted aggregate score.

The score is calculated as follows:

• For each of reviews, views, and comparisons, the product with the highest count in each area gets a maximum 18 points.
• Every other product gets assigned points based on its total in proportion to the #1 product in that area.
• For example, if a product has 80% of the number of reviews compared to the product with the most reviews then the product’s points for reviews would be 18*80% = 14.4.
• Both average rating and words/review are awarded on a fixed linear scale.
• For average rating, the maximum score is 28 points awarded linearly between 6-10 (e.g. 6 or below=0 points; 7.5=10.5 points; 9.0=21 points; 10=28 points).
• For words/review, the maximum score is 18 points awarded linearly between 0-900 words (e.g. 600 words = 12 points; 750 words = 15 points; 900 or more words = 18 points).
• If a product has fewer than 10 reviews, the point contribution for average rating and words/review is reduced: 1/3 reduction in points for products with 5-9 reviews, two-thirds reduction for products with fewer than five reviews.
• Reviews that are more than 24 months old, as well as those written by resellers, are completely excluded from the ranking algorithm. All products with 50+ points are designated as a leader in their category.
