The survey of more than 1,000 senior IT professionals revealed that demand for data storage is still growing, with 96% of respondents reporting an increase in their storage capacities. This is exactly the same rate of growth reported in the 2001 survey.
Messaging is once again the single biggest application driving this growth, with almost 70% of respondents citing e-mail as the biggest culprit.
Experts said the results underline the importance of developing an effective corporate e-mail strategy. Zarah Damji, research manager at analyst firm IDC, said, "E-mail is a huge headache - a lot of companies don't have a strategy in place for coping with e-mail capacity thresholds."
The research suggests that IT managers are becoming increasingly familiar with technologies such as storage area networks and network attached storage. In the most recent survey, 44% said they were already using or planning to use a San, compared with 35% in 2001.
Nas adoption is also growing, with 48% of IT managers either using or considering the technology - up from 39% last year.
