Mixing Flash, HDD Storage to Cater to Changing Workload Needs

By Chris Preimesberger  |  Posted 2014-07-15

New-generation data storage is all about NAND flash solid-state media, often simply referred to as flash. There's no question that it ranks among the hottest trends in the IT business and has been on that list for several years. As a result of this upsurge in demand, the market has become crowded with companies offering flash storage systems, including the biggest names in the data storage business. The reason? It's all about performance; the faster the media can absorb data, the more data can be stored and the more work can be done. Big data workloads, becoming more common in daily production all the time, are a major factor in all of this because performance is required for the vast number of enterprises dependent on data-driven applications. However, flash is not perfect; it's expensive and has a shorter lifespan of usability compared with hard-disk drives. Thus, for many enterprises, the best storage system marries flash with hard disk, using the benefits of each. This eWEEK slide show, developed with our own reporting and industry insight from Nimble Storage, offers pros and cons on this topic.
