More than one-third of total respondents to a recent ESG survey said their organizations are leveraging solid-state storage in some form today.

Based on a recent Enterprise Strategy Group (ESG) survey on solid-state storage adoption trends among 223 IT professionals, there’s no escaping the conclusion that solid-state storage -- once viewed with skepticism due to price and performance tradeoffs -- is becoming a mainstream part of enterprise storage environments. Survey participants represented enterprise-class organizations (1,000 employees or more) in North America. For the purposes of this survey, “solid-state storage” was defined as storage that uses solid-state memory (most frequently in the form of various types of flash memory, but can also include DRAM) to store data. That means it resides in a storage system (in the form of a solid-state drive or SSD), in a storage controller, in a server or in a standalone appliance. However, for the purposes of this survey, solid-state storage didn’t include solid-state drives for desktop or laptop PCs, or portable flash storage devices, such as USB drives.

Solid-state trends

To understand the relevance of the study, it’s important to note that it showed solid-state storage usage, not just awareness, is increasing. More than one-third of total respondents indicated their organizations are leveraging solid-state storage in some form today. In addition, 17% have plans to deploy the technology

within the next 12 months, while another 18% are in the evaluation phase. Given the pervasive media coverage of flash drive technology -- whether pertaining to enterprise IT systems or endpoint devices like laptops -- it’s not surprising that only 2% of respondents said they’re not familiar with solid-state storage.

While there are a number of ways to leverage flash memory to accelerate performance, SSDs are the most common type of solid-state storage implementation. Because the latest wave of solid-state usage started with enterprise data storage vendors shipping external disk storage subsystems with solid-state drives, it’s not surprising that nearly half of current users leverage this option today. Likewise, almost 50% of potential adopters expect to use solid-state drives in an external disk storage subsystem within the next 12 months to 18 months. Looking ahead, standalone solid-state storage appliances -- whether serving as primary storage or a cache -- appear poised to make the most significant gains over the next 18 months in terms of market adoption among both current users and potential adopters.
