No, it's not a fancy graphics card by OCZ that's pictured below, don't let the PCI-Express x16 interface and cooling assembly with vents and heat pipes sticking out fool you. This monstrosity is OCZ's R4, a complex PCI-Express solid-state drive (SSD) which packs 16 (!) SSD subunits, each driven by a SandForce SF-2200 controller. Each of the subunits is part of a very large RAID array, which is abstract to the host machine. The host only sees the cumulative capacity into a single volume.

At the heart of the beast is a spanking new VCA 2.0 processor, which provides each of those subunits a SATA 6 Gb/s link, and connects to the host over PCI-Express 2.0 x16. The sequential transfer speed of the R4 is up to 6,656 MB/s (megabytes per second). It will be offered in various capacities, 3.2 TB looks like a possible capacity option.

OCZ Technology Group, Inc., a leading provider of high-performance solid-state drives (SSDs) for computing devices and systems, and Marvell, a worldwide leader in integrated silicon solutions, today unveiled the industry's fastest and most versatile PCI Express (PCIe) storage system, the Z-Drive R5. The increased performance, reliability, and endurance of the Z-Drive R5 is designed to take PCIe-based solid state storage to the next level for enterprise environments.

The Z-Drive R5 features a jointly developed "Kilimanjaro" OCZ and Marvell native PCIe to NAND flash controller platform, allowing for completely scalable performance and redundancy while eliminating the need for a separate storage controller, thus reducing the cost to deploy high performance solid state storage systems in the data center.
