The use of flash storage in data centers is gathering a lot of momentum. The solid-state array market grew from about $240 million in 2012 to about $670 million in 2013, according to research from Gartner. Strong growth is expected to continue: IDC predicts that the market for all-flash arrays will grow at a compound annual rate of almost 60% a year, bringing the overall market to more than $1.2 billion by 2015.
There is good reason for this gathering momentum. Legacy hard disk drive (HDD) solutions have performance limitations, particularly when it comes to IOPS. These limitations can affect the performance of critical applications—particularly among I/O-intense workloads such as online transaction processing (OLTP), virtual desktop infrastructure (VDI), high-performance computing and big data analytics.
Flash addresses some of the performance challenges of HDDs—especially when it comes to IOPS and latency—and flash prices have come down significantly during the past…
