The internal process in the disk that makes these writes possible follows these steps: Is there any performance degradation when using 512e drives vs 512n? What if 512e drives are behind a compatible RAID controller and the RAID controller is exposing the 512n drives to vSphere? vSphere supports this configuration as long as the RAID controller is exposing the 512e drives as 512n format drives to vSphere. In order to keep performance constant, it is necessary that partitions on 512e hard drives be properly aligned (see also Partition Alignment) so that a 4KB sector contains exactly eight 512-byte blocks. 444" lift.
