Samsung PM893 and PM897 SATA SSDs deliver SATA Compatibility Extend the life of existing SATA based servers. Expand storage capacity with up to 7.68TB per SSD, extend the life of systems that rely on hardware RAID controllers, or bring your hard disk drive based server back to life with SSD performance. Flexible Family Portfolio Ten product variants covering a variety of common capacities (240 GB up to 7.68 TB) and write endurance levels of 1.3 DWPD and 3.0 DWPD. Address Data Center Challenges Data center architects face challenging requirements when delivering reliable computing and storage resources at the lowest total cost. Data center servers require high levels of I/O performance to keep their CPUs fully utilized, and high system density to minimize total cost. The storage systems that supply that I/O performance need to deliver consistent performance and latency to all tenant virtual machines and containers 24/7, 365 days a year. Flexible Family Portfolio Samsung's "ninth generation" SATA SSD families (PM893 and PM897) are available in capacities and write endurance levels to meet just about any application. For example, low capacity PM893 SSDs are ideal for high reliability, low power server boot drives. 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 PM893 and PM897 SSDs deliver performance up the maximum allowable for SATA attached drives: up to 560 MB/sec sequential access, and up to 98,000 IOPS for 4 kbyte random read 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. Hardware Encryption Engine Samsung's PM893 and PM897 SSDs keep your private data confidential, with encryption via a hardware based AES-XTS 256-bit encryption engine, and management via the TCG Opal 2.0 standard. Enterprise Power Loss Protection Samsung's PM893 and 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.
