USB 3.2 Gen 2 front-panel header
Pro WS X299 Sage II's front panel USB 3.2 header is ready for next-gen PC cases and devices.

M.2 & U.2
Achieve speed with onboard M.2 & U.2
Professional applications require fast solid-state storage, which is why the Pro WS X299 Sage II is equipped with dual M.2 slots and triple U.2 slots that are compatible with the latest NVMe SSDs. M.2 slots support longer 110 mm drives, and they can be configured into bootable RAID arrays connected directly to the CPU via Intel VROC technology.

VROC
Virtual RAID on CPU (VROC) is an all-new feature of Pro WS X299 Sage that enables use of an Intel VROC hardware key. With VROC, you can easily configure RAID arrays and eliminate traditional bottlenecks, so your storage is not held back by other traffic — perfect for busy scratch drives and content libraries.

Tune it your way
Comprehensive controls form the foundation of the ASUS X299 motherboards. The Pro WS X299 Sage II packs flexible tools to tune every aspect of your system to deliver the performance that you desire.
