Lightning® Write-Intensive 6Gb/s SAS Enterprise Solid State Drives

IT Managers are consistently challenged with the demand for higher performance and increased storage capacity for today’s data centers. Over time, HDDs have suffered from a performance decline creating a performance vacuum that SSDs can fulfill by acting as storage network accelerators. Enterprise SSDs provide substantial performance and footprint benefits over traditional HDDs. This enables IT service providers to replace hundreds of HDDs with a single SSD, realizing significant cost savings, while creating a more efficient and reliable network.

Since not all data centers are created equal, the key to achieving increased data and system performance is in understanding the specific application workload. Lightning Write-Intensive 6Gb/s (SAS) SSDs offer solid cost-to-performance benefits optimized for data management and endurance of high-speed storage and server environments. Available in 200GB and 400GB capacities, Lightning Write-Intensive SSDs provide an I/O pattern designed around frequent writes for application workloads such as Data Warehousing, High Performance Computing (HPC), Media Editing, Analytics and Database Logging, with a heavy workload comprised of a 50/50 read/write mix.

SSD performance is dependent on the grade of NAND flash memory used, and sophistication of the controller and firmware. Lightning Write-Intensive SSDs are designed with an advanced innovative controller that uses a parallel processing architecture with single firmware binary to provide the industry’s leading sustained performance, low response times under peak conditions for predictable performance, and proven and tested endurance for superior reliability. Lightning SSDs have been designed to meet demanding, mission critical, 24/7 applications.
