Enterprise Power Loss Protection. Samsung’s PM893 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 SSDs have been designed to prevent data loss resulting from unexpected power shutdowns with its PLP architecture.
