EMC has risen steadily in this survey and enters the winner's circle for the first time. Similarly, NetApp rose from prior disappointing results in the enterprise array category to join EMC at the top. Both companies posted overall scores of 6.53 on the survey's 1.0 to 8.0 scoring scale. NetApp is on a roll after winning top honors in the most recent NAS survey for its enterprise and midrange systems. Hitachi Data Systems Corp., the winner of all three previous enterprise array awards, fell to third place with a score of 6.50. And to further emphasize what a horse race this year's competition was, Hewlett-Packard (HP) Co. trailed Hitachi by a mere 0.01 of a point. IBM Corp. finished fifth with a 6.39.
