Samsung PM863a SSD for Data Centers  |  Keep Ahead of Ever-increasing Data Demands

Samsung PM863a solid state drives 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.

Stay On Top of Big Data

With the rise of personal, mobile, social and cloud computing, leading data centers are turning to SSDs to meet big data demands.

Samsung’s 3rd-generation V-NAND technology provides high capacities up to 3.84TB in the same 2.5-inch form factor. Boasting exceptional performance, endurance and power efficiency, the new Samsung SATA 2.5-inch PM863a SSDs deliver superb IOPS consistency, latency, and QoS (quality of service).

These high-performance SSDs provide the essentials for 24/7 data center environments. It's increasingly being adopted in all-flash array, JBOF (just bunch of flash) and HCIS (hyperconverged integrated systems) with qualified compatibility in the PM863.

Robust Performance

The PM863a is designed for mixed workload data center applications, such as CDNs (content delivery networks), streaming and web servers.

With sequential R/W speeds up to 520/480 MB/s and 4 KB random R/W speeds up to 97K/24K IOPS, it delivers robust performance under various heavy workloads. The PM863a maintains a strong IOPS consistency above 99% in random read performance and superior performance in random write speeds.

Lower TCO

Generating a better performance-to-power ratio than HDDs, the PM863a reduces data center operating costs, resulting in lower TCO (total cost of ownership).

Furthermore, by using the same 2.5-inch SATA interface, and with capacity options up to 3.84TB, IT managers can scale up their data centers using existing infrastructure.

Enhanced Data Integrity

The PM863a has a low probability of data corruption. End-to-end protection keeps data consistent along the entire data transfer path and Power Loss Protection safeguards data in the write cache in the event of a power failure.

Additionally, the Dynamic Thermal Guard algorithm monitors the SSD's temperature to help prevent thermal shutdown.

Self-encrypted Drives

The PM863a protects data with AES 256-bit hardware-based encryption. This encryption engine secures data without the performance degradation often experienced with software-based encryption.

A Technology Leader in Innovation

With innovation as its foundation, Samsung is one of the leading solution providers of world-class technology and scale. Samsung designs and integrates a wide array of critical SSD components in house, including the DRAM, NAND, controller, and firmware. Based on their intimate knowledge of every component, Samsung fine-tunes each element, enabling them to work in perfect synergy.


V-NAND Technology
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.

Sustained Performance
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.

IOPS Consistency
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.

Outstanding Reliability
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.

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.

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.
