LSI FSPs are the core of many of the most popular solid-state drives, sell for significantly higher prices than equivalent HD SSDs and have enhanced for more value. Our recent wins in the flash-enabled notebooks give us confidence that LSI will be the leader in this high-growth market segment in 2012.
In FSPs -- for enterprise SSDs, our momentum and share are also increasing. We are now shipping to 6 enterprise SSD OEMs, enabling us to gain significant share year-over-year in this space. Relative to the competition, we believe our FSP solutions deliver better performance, and that we provide not only flash storage processor silicon, but also firmware, manufacturing and test tools and turnkey SSD reference designs, improving our customers' time-to-market. In addition, we continue to support in production all 6 major flash vendors and are well-positioned to support the latest generation of flash.
In PCIe flash adapters, we are bringing the performance advantages of flash to enterprise server, storage and networking applications. We are focused on transparent acceleration of applications, and we encourage you to visit our website, thesmarterwaytofaster.com for additional information.
Last quarter, we introduced the Nytro product family, our second generation of PCIe flash adapters that incorporate our SandForce FSPs and offer a high performance with low latency, accelerating a broad spectrum of enterprise applications. Nytro is now in production, and we expect double-digit million revenue contribution from PCIe flash adapters in Q3, driven by ramps in high-performance data warehouse applications.
Last quarter, we announced that we were working with Cisco and EMC to bring the application acceleration benefits of PCIe flash cache and technology to Cisco UCS Blade Servers. We expect initial shipments in Q4.
In our SAS and RAID business, we continue to benefit from the ramp of Intel's Romley platform in addition to continuing to supply existing 6-gig SAS solutions to leading server OEMs. As customers begin migrating servers from 6-gig SAS to 12-gig SAS technology in the second half of '13, LSI is in the leading position to drive this transition. We are now sampling customers with our production 12-gig SAS rocks and has expanded our design win footprint to include 4 out of the top 5 server OEMs.
In external storage, Zyrtax [ph] has fully adopted our 12-gig SAS controllers and expanders, and we expect to begin initial shipments later this year.
