The OCZ Z-Drive R4 Series represents a turning point in the evolution of PCIe attached solid state storage by merging the best feature sets of both the pure hardware and pure software based approaches to data management. Designed and manufactured for a wide range of enterprise environments including cloud computing and data centers, the Z-Drive R4 features OCZ's Virtualized Controller Architecture™ (VCA) 2.0, providing the utmost in performance, flexibility, durability and enhanced reliability, allowing data centers to rely on a PCIe-based SSD as their primary tier one storage solution for the first time.

Additionally, the Z-Drive R4's level of concentrated performance enables system architects to design more productive infrastructures while lowering operating costs associated with hard drive technology.

VCA 2.0 supports the industry standard SCSI command set and, among a litany of other things, provides highly efficient performance aggregation due to our proprietary Complex Command Queuing Structure™ (CCQS), that handles balancing with OCZ's unique Queue Balancing Algorithm™, that extends the NAND flash life at a block level, manages redundancy, and is the software interface with the host system.

Z-Drives integrate seamlessly with servers at the system bus and kernel level, creating a new flash memory tier and dramatically increasing throughput and application performance all while slashing capital and operating costs.
