Samsung's SM863a SSDs feature V-NAND technology and are built from Samsung components. They are an ideal storage solution for write-intensive applications such as mail servers, data warehousing and high performance computing, providing high endurance for around the clock operations.

V-NAND Technology

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.


Built to handle the 24/7 operation and heavier workloads of data center usage, the SM863a 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.

Power-Loss Protection

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.

Outstanding Reliability

The SM863a is optimized for server and data center environments by offering reinforced endurance, enterprise-grade power-loss protection thanks to tantalum capacitors, low power consumption.
