As indicated earlier, overall user satisfaction was high, with 82% of respondents willing to make the same purchase decision again. In this important measure, IBM again topped NetApp, and this time in both categories. Its enterprise customers indicated a willingness to repurchase 90.9% of the time, and an even higher 95.5% of the time with midrange products. Previous surveys have often found high loyalty among IBM users.

Nevertheless, NetApp did have solid support among its users. In its case, 86.8% of enterprise users would make the same decision, while 82.4% of midrange users would do so. HP had solid numbers above 80%, while EMC had 78% (midrange) and 76.9% (enterprise). Sun trailed the enterprise group with a 64.3% user loyalty. Regardless, it's safe to say that while NAS users have the occasional bone to pick, they're apparently a happy group of people.

About the survey: The Diogenes Labs-Storage magazine Quality Awards are designed to identify and recognize products that have proven their quality and reliability in actual use. The results are derived from a survey of qualified Storage readers who assessed products in five main categories: sales-force competence, product features, initial product quality, product reliability and technical support. Products are rated on a 1.0-8.0 scale, where 8.0 is the most favorable score.

While our survey includes the spectrum of NAS vendors, a vendor must have at least 13 responses to be statistically valid and therefore considered as a finalist. This year, 274 respondents rated 492 systems. That's fewer respondents than 2007, but in line with the 2006 response rate. The lower response rate probably impacted smaller vendors the most, as we didn't have any of the smaller vendors crack the finalist list.

Just under half of the survey respondents (49.3%) had only one vendor, while the rest had two or more. The largest group of respondents was for the NetApp FAS2000/3000/6000 series of systems with 114. EMC Corp. Celerra had the second highest number of respondents with 67. Although the largest response groups were for enterprise systems, the survey was tilted toward the small- to medium-sized enterprise (SME). SMEs, or those organizations with less than $1 billion in revenue, comprise 62% of the survey respondents. The largest industry segment was financial with 6.3% of respondents, followed by IT services with 5.9%. Given that 14 different industries were represented, the survey population provided information from a broad spectrum of the marketplace.
