OCZ Z-Drive R5, Kilimanjaro Platform Announced
20.05.12
The key benefits of the Z-Drive R5 and the Kilimanjaro platform center around the way the drive interfaces with the host machine - in this case, a native PCIe to NAND flash controller platform, which allows for scalability without the need for a separate storage controller. Kilimanjaro is powered by the brand new Marvell 88NV9145, which is the first modularly scalable native PCIe SSD controller available in mass production.

The Marvell 88NV9145 is modular as shown above in its reference design and scales in performance extremely well. Shown below is a chart Marvell shared with us describing the performance increases as more modules are added to the design.

Each module feeds into a primary controller, which is similar in look to the layout of the enterprise-focused OCZ Z-Drive R4 and consumer-oriented RevoDrive 3 X2 with one key difference. With a native PCIe storage solution you bypass the SATA interface completely and remove the need for an onboard SATA RAID chip that ties all the SSDs together, like in the Z-Drive R4 for instance. Native PCIe is thus faster by avoiding the this bottleneck.
