Optimus® Product Family of SAS SSDs

Optimus ®  Product Family of SAS SSDs

Overall positioning and core values of the product

SanDisk Optimus ®  The SAS Solid State Drive series is a high-performance storage product aimed at the enterprise market, specializing in mixed load and write intensive application scenarios. It is equipped with a native SAS 6Gb/s interface and can be seamlessly integrated into existing enterprise infrastructure, adapting to devices with strict performance and high availability requirements such as servers, external storage arrays, and Storage Area Networks (SANs). The core value of the product lies in the application of innovative IP and Multi Layer Cell (MLC) flash memory, allowing OEM manufacturers and IT managers to achieve high cost-effectiveness without compromising on performance, durability, and reliability, and realizing the integrated integration of the four core characteristics.

Core performance and basic specifications

The Optimus series SSDs have industry-leading hardware performance and flexible capacity selection, with clear key digital indicators and support for performance expansion. The specific parameters are as follows:

Write durability: Supports 10-50 random drive writes per day, meeting high-frequency write requirements;

Capacity version: Provides multiple capacity options including 100GB, 200GB, 400GB, 800GB, and 1.6TB to meet different storage needs;

Read and write performance: Random read/write performance up to 100K/45K IOPS, continuous read/write speed up to 500/500 MB/s;

Performance Expansion: Supports wide port SAS functionality, and in applications adapted to this feature, the continuous read performance can be improved to 1GB/s;

Basic guarantee: Provides a 5-year warranty, with data integrity reaching BER 10 ¹⁷, ensuring long-term stable use.

Core security and compliance features

The product comes standard with multiple high-end security and compliance functions, providing comprehensive basic protection for enterprise data:

Data Encryption: Supports AES 256 bit encryption to achieve full lifecycle encryption protection for data;

Industry compliance: Complies with TCG enterprise standards and meets the compliance requirements of the enterprise market;

Data integrity: The core indicator of BER 10 ¹⁷ ensures the accuracy of data transmission and storage from the bottom layer.

Core Technology Platform: Guardian Technology ™

Optimus series SSDs are based on SanDisk Guardian Technology ™ Built on an exclusive technology platform, this platform is powered by * * FlashGuard ™、 DataGuard ™、 EverGuard ™**  The three core technologies, namely flash memory durability, data integrity, and device operation reliability, are the core competitiveness of the product, achieving technological breakthroughs in these three dimensions:

FlashGuard ™ technology

Core function: Significantly enhance the native durability of MLC flash memory, increasing the write capability of commercial grade MLC flash memory from less than 1 write per day to 50 full capacity writes per day;

Technical principle: Integrating aggregated flash memory management (treating all flash components as a single system) and advanced signal processing (dynamically adjusting flash parameters throughout the entire lifecycle), combined with proprietary enhanced error correction (ECC) technology, MLC flash memory can be stably applied to mixed load and write intensive scenarios.

DataGuard ™ technology

Core function: Full data path protection, preventing user data damage in all data paths within the SSD, while ensuring that page/block level data is not lost;

Core feature: Equipped with * * F.R.A.M.E. (Redundant Array of Flexible Memory Components) * * technology, as an exclusive data recovery function, even in the event of catastrophic events such as flash page/block failures, user data can still be recovered.

EverGuard ™ technology

Core function: Ensure reliable operation 24/7 and prevent user data loss caused by unexpected power outages;

Technical principle: Adopting the third-generation backup power circuit design and high reliability discrete capacitors, it provides emergency power supply for data storage in the event of a power outage, ensuring data integrity.

Product Model Classification and Adaptation Scenarios

The Optimus series is divided into three main models, designed for two core application scenarios: mixed load and write intensive. The scenarios cover enterprise level requirements across the entire industry, and the classification and adaptation are as follows:

（1） Optimus (Hybrid Load Edition)

Adapt to mixed load scenarios with multiple types of business interactions and conventional data reading and writing, including online transaction processing (OLTP) databases, financial transactions, e-commerce, data warehouses, enterprise infrastructure, email/messaging services, virtual desktops, and collaborative office.

（2） Optimus Ultra/Ultra+(write intensive version)

Adapt to write intensive scenarios mainly focused on high-frequency data writing and high computing power data processing, including data warehousing, high-performance computing, oil and gas exploration, life sciences, aerospace, engineering design, media editing, data analysis, and database logging.
