So, you want more capacity and better performance from Intel's Intel's Optane SSD 800P? It's easy to accomplish with Intel RST RAID. You can do it with either RAID 0 boot volumes or RAID 0 secondary volumes. We aren't going to bother with a boot volume for this review because we just don't have the time to do so before product launch.

If you intend to create a bootable RAID volume, you will need to enable SATA RAID mode in your system BIOS and inject the latest RST driver into your Windows install. To create a secondary RAID volume, like we did here, you also must set SATA to RAID mode in the system BIOS and install Intel's RST RAID Utility so write-back caching can be enabled. RST RAID is limited by chipset bandwidth which tops out at about 3.6GBs with overhead.


This is our 3-drive RST array as we created it. We didn't have time to play around with stripe sizes, so we just went with default 16KB stripes. We enabled write-back caching and disabled buffer-flushing. We also disabled link power management.


Almost double the storage bandwidth compared to a single drive on its own.
