Overview:
CloudSpeed Ascend™ SATA SSDs from SanDisk are the next generation of 19nm eMLC NAND flash technology, providing higher performance than the previous generation and are optimized for enterprise server and cloud computing environments. CloudSpeed Ascend SSDs are ideally suited for read-intensive applications such as, File Servers, Web-based Applications and Virtual Tape Libraries (VTL). The CloudSpeed Ascend SSDs excellent price-performance makes it an ideal replacement for hard disk drives.
Available in capacities of 120GB to 960GB, CloudSpeed Ascend SSDs feature a 6Gb/s SATA interface and provide data transfer rates up to 470/450 MB/s sequential read/write and performance up to 70K/14K IOPS random read/write. CloudSpeed Ascend SSDs offer high data integrity by employing a combination of powerful error correction and detection, full data path protection, thermal monitoring, and data fail recovery.
Guardian Technology™ Platform
CloudSpeed Ascend SATA SSDs are powered by SanDisk’s proprietary Guardian Technology Platform, a suite of enterprise features that include 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 cost-effective 19nm cMLC flash, making it suitable for read-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 genearation backup power circuit design and high-reliability discrete capacitors.
