Through a combination of unique and innovative IP, and the use of enterprise MultiLevel Cell (eMLC) flash, SanDisk’s newest generation of 19nm eMLC SSDs feature a native SAS 6Gb/s interface, outstanding performance metrics, and a comprehensive set of high-end features making them ideal to integrate with existing infrastructure for a wide variety of enterprise environments such as servers, external storage arrays, and storage area networks (SAN) where performance and high-availability are required. Available in capacities of 100GB – 2TB*, Optimus SSDs provide random read/write performance up to 95K/40K IOPS and sequential read/write data transfer rates of up to 550/540 MB/s**. The Optimus SSD portfolio has been designed to offer a range of performance and capacity solutions for a variety of applications that include mixed-use, read-intensive and write-intensive workloads. Optimus SSDs range from 1 - 45 full random drive writes per day (DWPD).
Guardian Technology™ Platform
The product family of Optimus SAS SSDs is powered by SanDisk’s proprietary Guardian Technology Platform, a comprehensive suite of enterprise features comprised of FlashGuard™, DataGuard™ and EverGuard™ technologies.
FlashGuard Technology combines Aggregated Flash Management, which treats all flash elements as a single system, and Advanced Signal Processing, which dynamically adjusts flash parameters throughout the life of the SSD, to reliably extract significantly more life from commercial-grade MLC flash, making it suitable for mixed-use, read-intensive and write-intensive application workloads.
DataGuard Technology features full data path protection, safeguarding user data from corruption along all data paths in the SSD.
EverGuard Technology protects against loss of user data in the event of unexpected power interruptions using a 3rd generation backup power circuit design and highreliability discrete capacitors. Optimus SAS SSDs are designed for I/O intensive, mission-critical, 24/7 applications.
