OCZ Ships Next-Generation SSDs

By Stuart J. Johnston

OCZ Technology said this week that it has released a new generation of its solid-state drives (SSD) built on the PCI Express (PCIe) standard.

The new release, called Z-Drive Revision 4 (R4), uses OCZ's second-generation Virtualized Controller Architecture (VCA) 2.0 to enable customers to use PCIe-based SSDs as primary tier one storage, according to a statement from the San Jose, Calif.-based company.

OCZ's Z-Drive R4 is designed to take advantage of the multifaceted virtualization layering of VCA 2.0 to interface with the company's SuperScale Storage Controller.

"When coupled with VCA 2.0 technology, the SuperScale Controller manages critical internal functions such as OCZ's intelligent Complex Command Queuing Structure (CCQS) with unique queue balancing algorithms [that] leads to superior performance aggregation, and results in significantly higher throughput and reduced burden on the host CPU," OCA's statement added.

The company claims that a single SuperScale Controller equipped with a Z-Drive R4 can transfer up to 2.8 GB per second and complete as many as 500 K input/output operations per second (IOPS).

Additionally, a dual SuperScale Controller card can transfer 5.6 GB per second and complete 1.2 million IOPS, OCZ claims.

"The demand for higher performing PCIe-attached solid state storage continues to grow, and our new Z-Drive R4 represents an increased focus to meet the needs of its enterprise and data center clients," Ryan Petersen, CEO of OCZ Technology, said in a statement.

"The Z-Drive R4 provides the best of both worlds for storage architects by merging the industry-leading feature sets of both the pure hardware and pure software based approaches to data management, while maintaining user-configurable flexibility not found in other devices.," Peterson added.

The Z-Drive R4 also features power failure protection so that data isn't lost when the power goes down.

Further, the Z-Drive 4R is available in either half-height or full-height rackmount form factors, and both support single-level cell (SLC) and multi-level cell (MLC) NAND Flash memory.
