Samsung's PM897 SSDs offer increased write endurance, making them ideal for mixed read/write workloads, such as a general-purpose or dedicated cache tier in a hyper-converged infrastructure like VMware's VSAN, logging applications, online transaction processing (OLTP), database servers, and other general-purpose servers with legacy workloads that have unknown write characteristics. All SSDs in this series use the same Samsung controller and V-NAND flash memory to simplify customer qualification and ensure reliable large-scale delivery.
