VMDK vs CPIO: Key Differences

•VMDK and CPIO diverge on compression: lossless compression for the source, lossless compression for the target.
•Since both VMDK and CPIO use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
•Transparency: N/A
•File sizes: VMDK files typically range Up to 2TB per virtual disk, uses sparse allocation and CPIO files Similar to TAR for same content.
•VMDK is optimized for vmware virtual machines, virtual disk storage while CPIO is designed for linux initramfs, unix software packaging — choose based on your specific workflow needs
