Pure Storage is a pure play in computer storage. The company sells flash storage only and none of those old-school hard disk drives (HDD) which have been the storage devices of choice for decades. Since flash storage offers faster response than HDDs, Pure focuses on customers with needs in virtualization and transaction processing. The company’s products include its solid state drives, Flash Array, the software that operates the drives, the Purity Operating System, and Pure1, which provides cloud-based management and support to customers. Like a consumer product company, Pure offers a 30-day, money back guarantee of its products.
