In summary, the design of FVD takes a principled approach to achieve the following benefits: Strive to make the on-disk data layout identical (or at least as close as possible) to that of a RAW image stored on a raw partition. Eliminate the overhead of a host file system when it can be avoided.
60:
FVD can be written either directly to a physical or logical blockstore (avoiding host filesystem overheads), or to a regular host file system file. It strives to maintain similarity to raw disk layouts, eliminate host filesystem and disk image

Eliminate the overhead of a compact image when it can be avoided. Minimize disk I/O overhead for reading on-disk metadata by reducing metadata size. Minimize disk I/O overhead for updating on-disk metadata.

Convention: Any item in this table that has the form of "A+B" or "A+B+C" indicates a disk format that spans multiple files, where A contains the bulk of the data, and B and C are
