How Many IOPS is Enough?
IT professionals find it difficult to determine which SSD or flash array to buy or even whether they can get the speed they need from standard HDDs. There is an extraordinarily wide rage of IOPS (from hundreds to millions), latencies, and capacities, and this can be confusing. This 2017 update to our rigorous 2012 report provides, through a survey of nearly 260 IT managers and other end users, a good understanding of the needs of various applications including IOPS, latency, and capacity.
The 157-page report, jointly produced by Objective Analysis and Coughlin Associates, dissects the results of a months-long on-line survey of IT managers which collected their inputs on the IOPS, capacity, and latency needs for a number of key enterprise applications. Through its 136 figures and eight tables the study sheds new light on the speed requirements for certain key applications like OLTP, database management, and cloud services.
