My thought is to use the 280GB drive as cache, but carve a piece of it to use for the windows swap file.ģ. if the above is possible (or at least working), can i split the drive, i.e. can the 900P be used as cache ? i understand it actually works - see here, but is it officially supported ?Ģ. I understand that the new RST drivers will support using Optane as Cache for a secondary driveġ. I have a system with a 2TB SSD boot drive and a 4TB secondary SATA drive,
