PM863a 1.9TB 2.5" SATA-3 Enterprise Class Solid State Drive (MZ7LM1T9HMJP-00005)Samsung’s PM863a SSDs feature V-NAND technology and are built from Samsung components. They are designed to deliver exceptional around the clock performance for your Data Center and Server data storage needs, focused on read-intensive applications such as streaming services, content delivery networks, web servers and cloud services.
Samsung's V-NAND flash memory helps to overcome the limitations of conventional planar NAND architecture. It stacks 48 cell layers vertically over one another rather than trying to fit itself onto a fixed horizontal space, in order to provide high density and performance with a small footprint.
Built to handle the 24/7 operation and heavier workloads of data center usage, the PM863a delivers an exceptionally high level of sustained performance and consistent low latency over the life of the SSD to meet the demands for increasing data handling.
When combined in RAID configurations with multiple drives, small variations are multiplied and lead to significant effects on performance. The PM863a delivers an exceptional level of performance above 99% in random read, as well as superior performance in random write.
The PM863a is optimized for server and data center environments by offering reinforced endurance, enterprise-grade power-loss protection thanks to tantalum capacitors, low power consumption and a 3-year limited warranty.
Latency and QoS
The PM863a offers extremely low latency and a high level of Quality of Service (QoS), which are both essential for data center and cloud server applications.
Advanced ECC Engine and End-to-End Data Protection
Detect signal discrepancies and proactively remedy them in real time with the Error Correcting Code (ECC) engine.
Protect data integrity from unexpected power loss with Samsung's advanced power-loss protection architecture. Using the electricity from a tantalum capacitor to provide enough time to transfer the cached data in the DRAM to the flash memory, you can be assured no loss of data.
Monitor the computer drives proactively to detect and report various reliability indicators with Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T).
Dynamic Thermal Guard Protection
Safeguard the SSD from overheating by automatically controlling the speed of the CPU relative to its core temperature, by throttling back the performance to prevent thermal shutdown.
