![]() ![]() 1 Client SSDs are designed with minimal native OP to minimize cost, while data center and enterprise SSDs tend to have more OP to improve steady state performance and endurance. However, if there is spare user capacity on the drive, this results in an increase of usable OP. When the drive is completely filled, it has only the native OP enforced by design. The more data on a drive, the less spare capacity is available for the drive to use as OP. All flash-based SSDs contain some level of OP. ![]() What Is Over-Provisioning Over-provisioning (OP) on a flash-based SSD refers to spare NAND capacity that the drive may use to optimize internal processes. This tech brief will cover how to over-provision the M600 to enable data center applications and how to implement that configuration using Micron s Storage Executive command line interface (CLI) tool. Some of these differences can result in unforeseen challenges which can be mitigated by implementing overprovisioning and performing application-modeled tests on the drives during qualification. In practice, there are differences in how clientoriented SSDs like the M600 and those targeted for the data center, such as Micron s M500DC or M510DC, are designed and specified. Many see Micron s M600, with its industry-leading endurance, as a natural choice for this adoption trend. ![]() 1 A MICRON TECHNICAL MARKETING BRIEF Over-Provisioning the M600 SSD for Data Center Applications Background Storage architects are turning to SSDs traditionally aimed at client usage models for some of their more cost-sensitive applications due to their approachable price point. ![]()
