Nearly all organisations (90%) now have some form of flash storage in their datacentres, with flash as a tier in hybrid flash arrays the most common in use (51%), according to a survey by 451 Research.
The Voice of the Enterprise: Storage study by 451 was conducted among more than 1,000 IT professionals worldwide and combined with responses from a panel of more than 30,000 senior IT buyers and enterprise technology executives.
With hybrid flash the most common method of flash adoption, a further 29% plan to deploy flash as a tier in the next two years.
All-flash array adoption is growing most rapidly, with 27% of enterprises having gone down this route and a further 28% planning to deploy all-flash arrays in the next two years.
Respondents were also asked what their all-flash deployments support, which revealed that three-quarters support multiple applications, while a quarter support single applications. The top two use cases for all-flash deployments are databases and virtual desktop infrastructure (VDI), while data analytics is expected to be a top two use case within two years.
Data deduplication and compression are in use by a majority of organisations that have deployed flash, with most respondents (59%) saying they gain between two and five times more space savings from using these technologies.
The study revealed that the traditional storage suppliers, led by EMC, dominate the all-flash market, but smaller specialists such as Pure Storage are popular, with a quarter of respondents saying they might buy Pure Storage in 2016.
A sizeable minority of organisations (19%) said they will entirely replace spinning disk technology for SAN-based storage workloads over the next two years. Cost was cited as the biggest barrier to all-flash array adoption, with 51% saying they are too expensive. A further 47% said their existing storage performance was sufficient.
