<b>V-NAND Technology</b>
Samsung's V-NAND flash memory helps to overcome the limitations of conventional planar NAND architecture. It stacks 32 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.
<b>Sustained Performance</b>
Built to handle the 24/7 operation and heavier workloads of data center usage, the PM863 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.
<b>IOPS Consistency</b>
When combined in RAID configurations with multiple drives, small variations are multiplied and lead to significant effects on performance. The PM863 delivers an exceptional level of performance above 99% in random read, as well as superior performance in random write.
<b>Outstanding Reliability</b>
The PM863 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.
<b>Latency and QoS</b>
The PM863 offers extremely low latency and a high level of Quality of Service (QoS), which are both essential for data center and cloud server applications.
<b>Advanced ECC Engine and End-to-End Data Protection</b>
Detect signal discrepancies and proactively remedy them in real time with the Error Correcting Code (ECC) engine.
<b>Power-Loss Protection</b>
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.
<b>S.M.A.R.T.</b>
Monitor the computer drives proactively to detect and report various reliability indicators with Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T).
<b>Dynamic Thermal Guard Protection</b>
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.
