Why each option
vFlash Read Cache requires a minimum of Virtual Hardware Version 10, which was introduced alongside the feature in vSphere 5.5.
Virtual Hardware Version 8 corresponds to vSphere 4.x and predates the vFlash Read Cache feature by multiple major releases.
Virtual Hardware Version 9 was introduced in vSphere 5.1, which also predates the vFlash Read Cache feature introduced in vSphere 5.5.
Virtual Hardware Version 10 was introduced in vSphere 5.5, the same release that debuted vFlash Read Cache. A VM must be at hardware version 10 or higher to have a vFlash Read Cache reservation configured on its virtual disks, as the capability depends on hardware-level features exposed in that version.
Virtual Hardware Version 11 supports vFlash Read Cache but is not the minimum required version - version 10 is sufficient and is the correct minimum.
