Enterprise SSD SM863a (OEM)
SSD for write-intensive data centers
With a higher level of endurance, the SATA 2.5-inch SM863a Solid State Drive (SSD) isthe ideal choice for write-intensive applications such as servers for OLTP (online transaction processing),email and database.
Sustain endurance with V-NAND technology
The SM863 is designed with Samsung V-NAND technology to provide all the essentialsfor 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.
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 degradationoften 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 pathand 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 SSDin order to prevent thermal shutdown.
Technology leader in innovation
Samsung is a leading solution provider that designsand 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.
