![]() ![]() ThinkSystem PM1643a Entry 12Gb SAS SSDs Server support The following tables present technical specifications for the PM1643a Entry SSDs. 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. A solid-state device will not fail upon reaching the specified TBW. It simply denotes the maximum number of writes that can be guaranteed. Reaching this limit does not cause the drive to immediately fail. 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). ![]() SD 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. Entry SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Mainstream or Performance SSDs. SSDs have a huge but finite number of program/erase (P/E) cycles, which affect how long they can perform write operations and thus their life expectancy. ![]() Compliant with SCSI Specification (SAS-3 / SPL-3 / SBC-4 / SPC-4 / SAM-5).Support 16 Initiator with Tag Command Queuing (TCQ) Command Set with a queue-depth of up to 128 commands.Supports Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T).Protect data integrity from unexpected power loss with Samsung’s advanced power-loss protection architecture.2.5-inch or 3.5-inch industry standard form factor with hot-swap tray.Endurance of 1 drive-write per day (DWPD) over 5 years.Based on Samsung 64-layer V-NAND technology and TLC flash memory.Enterprise-grade SSD suitable for read-intensive workloads.The ThinkSystem PM1643a Entry SAS SSDs have the following features: MHRA 'SPC', All Acronyms, 13 February 2023, Bluebook All Acronyms, SPC (Feb.
