    SSD SM863a SSD for write-intensive data centers

SM863a

Overview

SSD for write-intensive data centers

With a higher level of endurance, the SATA 2.5-inch SM863a Solid State Drive (SSD) is the ideal choice for write-intensive applications such as servers for OLTP (online transaction processing),email and database.

SSD for write-intensive data centers

Sustain endurance
with V-NAND technology

The SM863 is designed with Samsung V-NAND technology to provide all the essentials for data center environments - more capacity, speed, endurance and power efficiency. . As a result, the SM863a is optimal for 24/7 data center operations under heavy workloads.

Accelerate performance

The SM863a delivers outstanding 4 KB random read/write IOPS of up to 95,000/28,000. . It also boasts exceptionally low latency and a high level of QoS(Quality of Service), imperative for fast processing servers.

Increase data security

The SM863a protects data with AES 256-bit hardware-based encryption. This encryption engine secures data without the performance degradation often experienced with software-based encryption.

Ensure data integrity

The SM863a demonstrates 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 power failure. The Dynamic Thermal Guard algorithm monitors the temperature of the SSD in order to prevent thermal shutdown.

Technology leader in innovation

Samsung is a leading solution provider that designs and integrates critical components of the Solid State Drive in house. Because Samsung has intimate knowledge of every component and is a leader in V-NAND technology innovation, it can fine-tune each element and create perfect synergy.
