Mosaid Technologies this week introduced HLSSD (HyperLink solid-state drive), a SSD that achieves terabyte-class storage capacity using a single controller device. The solid-state drive utilizes Mosaid's proprietary HLNAND technology. The developer hopes that its HLSSDs will become cost-efficient high-performance storage solutions for enterprises.


Mosaid’s prototype HLSSD utilizes a single FPGA-based Serial ATA III controller to deliver 2TB capacity over four HLNAND channels, with 16 32GB HLNAND flash MCPs (multi-chip packages) per channel. In comparison, a conventional 2TB SSD requires four SATA controllers, plus a Serial ATA III hub controller, operating over 32 channels.

HLNAND flash is a proprietary high-performance solution that combines Mosaid's own HyperLink memory technology with industry standard NAND flash cell technology to deliver advanced feature set, reaching sustained I/O input-output bandwidths more than ten times higher than conventional flash, according to Mosaid.

Mosaid’s terabyte-class HLSSDs are optimized for data centers and the enterprise. Based on HLNAND (HyperLink NAND) technology, Mosaid’s HLSSDs deliver scalability, performance, reliability and cost advantages over SSDs that use conventionally designed NAND flash devices.

Today’s data centers are designed with up to four tiers of storage devices: lower cost, lower performance tape drives and Serial ATA HDDs, and higher cost, higher performance SAS HDDs and SSDs. This architecture necessitates advanced intelligence in the storage arrays to determine which data to allocate to the faster SAS HDDs and SSDs.

With Mosaid’s terabyte-class HLSSDs, only two storage tiers are needed: Serial ATA HDDs and HLSSDs. As a result, the requirement for advanced intelligence is reduced, as is the total costs of ownership, including power, footprint, cooling, maintenance and other elements, according to the company.

“Our affordable and scalable terabyte-class HLSSDs will be an enabling technology in data center and enterprise applications. HLSSDs can be used to build large, fast storage pools that lower the total cost of ownership by reducing the number of storage tiers, and minimizing the need for advanced intelligence in the storage arrays,” said Jin-Ki Kim, vice president of research and development at Mosaid.

In mid-2013, Mosaid plans to release a 2TB/4TB/8TB production HLSSD that will use a purpose-built HLNAND flash controller in 40nm process technology.
