Lightning Ascend™ Gen. II SAS SSD
Maximum bandwidth with high speed data transfer rates where quick access to data is essential
The Lightning Ascend™ Gen. II 12Gb/s SAS SSD doubles interface speed, providing the highest performance for mission-critical hyperscale, cloud and virtualized data center application workloads.This next generation Lightning® SSD offers a feature-rich robust design, combined with SanDisk’s innovative parallel processing architecture to deliver full data path protection (T10-DIF support), temperature based power control, SED instant secure erase, an MTBF of 2.5 million hours and power fail protection. This SSD is backward-compatible with 6Gb/s SAS and offers a single firmware binary platform for seamless integration and reduced qualification times.
Lightning Ascend Gen. II SAS SSDs offer superior reliability with high speed data transfer rates where quick access to data is essential. Available in 19nm eMLC capacities from 200GB – 1.6TB2 and with random read/write performance of up to 195K/100K IOPS* and sequential read/write speed of up to 980/600 MB/s1/*. These SSDs are designed for mixed-use applications such as On-line Transaction Processing (OLTP) Databases, Email/Messaging, E-Commerce, Virtual Desktop Infrastructure, and Collaboration with a typical workload comprised of a 70/30 read/write mix. This SSD offers 10 full drive writes per day (DWPD) with a limited 5 year warranty.
Lightning Ascend Gen. II SAS SSDs are a product of SanDisk’s vertical integration - spanning from the fabrication of the NAND technology and wafer to the manufacturing of the finished SSD. This vertical integration results in a customized solution that takes full advantage of each component to deliver maximum performance and quality assurance. Lightning Ascend Gen. II SSDs provide high, predictable-performance, industry-leading reliability and maximum value.
