Hitachi releases new 1.6TB flash modules

Lucas Mearian | Nov. 9, 2012
HDS's new flash module is built specifically for enterprise-class workloads. The 1.6TB module fits in an 8U flash chassis. Each enclosure can scale from 6.4TB up to 76.8TB.

HDS said it would not provide pricing for its drives or storage platforms, "but based on our calculations, Hitachi Accelerated Flash storage is up to 46% lower in cost when compared to an MLC SSD of similar capacity," a spokesman wrote in an email reply to Computerworld.

Hitachi Accelerated Flash storage introduces several new capabilities including inline write compression that speeds writes on flash and improves MLC flash memory endurance. When compared to standard 400GB MLC SSDs, Hitachi Accelerated Flash storage has four times better performance, improved environmental characteristics (power and space), the company said.

Hitachi Accelerated Flash storage is fully compatible with all Hitachi VSP features, including Hitachi Dynamic Tiering (HDT), which allows data to be moved to different tiers of storage based on use patterns.

"Today's announcement is a milestone achievement in how flash technology will be used in the enterprise data center moving forward," Basilio said in a statement. "Hitachi Accelerated Flash storage is the first flash device that is optimized for the performance and reliability required for mission-critical applications."
