Desktop, Nearline and Enterprise Disk Drives - Delta by Design

For the past twenty five years the storage marketplace has been divided into two major categories namely "Desktop" and "Enterprise". Recently, a third player variously known as "Nearline", "Reference" or "Business Critical" has evolved to provide a low cost, high capacity storage solution for Enterprise data that no longer needs to exist in a high availability transactional processing environment, but must maintain 24 x 7 availability as a reference or backup resource. Each of these classes of drives requires a unique and specific set of attributes to fulfill its role. This presentation will explore these differences and explain why you need to use the right drive for the right application.
