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 of hyper-converged infrastructure like VMware’s VSAN, logging applications, online transaction processing(OLTP), database servers, and other general purpose servers with legacy workloads with unknown write characteristics. All SSDs in this lineup use the same Samsung controller and V-NAND flash memory, to simplify customer qualification and ensure reliable high volume supply.
• SATA Interface Saturating Performance
Samsung’s PM897 SSDs deliver performance up the maximum allowable for SATA attached drives: up to 560 MB/sec sequential access. Maximum performance not only allows your workloads to complete a quickly as possible, but also allows efficient shared use of high capacity drives, to maximize the performance per gigabyte of data stored.
• Enterprise Power Loss Protection
Samsung’s PM897 SSDs include enterprise power loss protection (PLP). During normal power-off periods, the host server allocates time to preserve data integrity by transmitting a standby command to each device. In the event of an unexpected power loss, though, the cached data in a storage device’s internal DRAM buffers can be lost. This can occur with unexpected power outages, or when users unplug devices from the system. However, the Samsung PM893 and PM897 SSDs have been designed to prevent data loss resulting from unexpected power shutdowns with its PLP architecture. Upon detection of a failure, the SSD immediately uses the stored energy from their PLP capacitors to provide enough time to transfer the cached data in DRAM to the flash memory, ensuring no loss of data.
