Abstract The Lenovo ThinkSystem PM883 Entry SATA 6Gb solid-state drives (SSDs) in capacities ranging from 240 GB to 7.86 TB are general-purpose SSDs based on the Samsung PM883 platform. They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads. This product guide provides essential presales information to understand the PM883 Entry SATA SSD offerings and their key features, specifications, and compatibility. This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the SSDs and consider their use in IT solutions. Change History Changes in the January 7 update: - Added SR850P to the server support table - Server support section Introduction The Lenovo PM883 Entry SATA solid-state drives (SSDs) in capacities ranging from 240 GB to 7.86 TB are general-purpose SSDs based on the Samsung PM883 platform. They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads. Entry SSDs and Performance SSDs have similar read and write IOPS performance, but the key difference between them is their endurance (or lifetime) (that is, how long they can perform write operations because SSDs have a finite number of program/erase (P/E) cycles). Entry SSDs have a better cost/IOPS ratio but lower endurance compared to Performance SSDs. SSD write endurance is typically measured by the number of program/erase (P/E) cycles that the drive incurs over its lifetime, listed as the total bytes of written data (TBW) in the device specification. The TBW value assigned to a solid-state device is the total bytes of written data (based on the number of P/E cycles) that a drive can be guaranteed to complete (% of remaining P/E cycles = % of remaining TBW). Reaching this limit does not cause the drive to immediately fail. It simply denotes the maximum number of writes that can be guaranteed. A solid-state device will not fail upon reaching the specified TBW. At some point based on manufacturing variance margin, after surpassing the TBW value, the drive will reach the end-of-life point, at which the drive will go into a read-only mode. Because of such behavior by Entry solid-state drives, careful planning must be done to use them only in read-intensive or mixed up to 70% read/30% write environments to ensure that the TBW of the drive will not be exceeded before the required life expectancy. For example, the 480 GB PM883 Entry drive has an endurance of 683 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 374 GB of writes per day, which is equivalent to 0.8 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 624 GB of writes per day, which is equivalent to 1.3 full drive writes per day.
