"OCZ Technology Launches Next Generation Z-Drive R4 PCI Express
 Solid State Storage Systems"

 The Z-Drive R4 Provides the Ultimate Solution for Big Data and
 Cloud Computing Applications by Coupling Enterprise-Class Power
 Fail Protection with Benchmark-Shattering Performance
 August 2, 2011

  "today announced the release of Z-Drive Revision 4 (R4) PCI Express
  (PCIe) storage solutions designed to dramatically accelerate
   enterprise applications and significantly reduce total cost of
   ownership in the data center. The Z-Drive R4 product line features
   OCZ's second generation proprietary Virtualized Controller Architecture
   (VCA) 2.0, providing the utmost in performance, flexibility,
   durability and enhanced reliability features, allowing data centers,
   for the first time, to rely on a PCIe-based SSD as their primary
   tier one storage solution."

  "The OCZ Z-Drive R4 is truly unique, melding hardware and software
   managed solutions with integrated VCA 2.0. This brings traditional
   SSD technology into a new realm and enhances performance, deployment
   capabilities, and endurance. VCA 2.0 is a multifaceted virtualization
   layer and interfaces with the OCZ SuperScale Storage Controller
   which combines processing and full DMA (direct memory access) cores,
   as well as internal PCIe, SATA and SAS physical interfaces.
   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. This combination leads to superior performance aggregation
   and results in significantly higher throughput and reduced burden on
   the host CPU."

"OCZ’s latest Z-Drive R4 series PCIe SSD"

Z-drive series

  "OCZ offers two versions of their Z-drive the R and C series, both of
   which offer the same capacities and high performance but as far as
   I could tell the R series appears to be have more enterprise class
   availability and functionality. Specifically, this drive has power
   fail protection for the writes (capacitance power backup) as well
   as better SMART support (with "enterprise attributes"). These both
   seem to be missing from their C Series drives."
