Once past first impressions, the bottom line for any storage system is whether it does what you need it to do. In the product features category, we ask users to consider the functionality of their systems and whether the features meet their needs.

EMC's win in the enterprise group was by the slimmest of margins: 6.86 vs. NetApp's 6.85 -- essentially a dead heat.

One survey respondent whose company has "several dozen" EMC boxes installed noted he was "extremely pleased and always [has] been regarding the reliability and scalability of EMC systems."
