When Should You Use VMDK vs RAR?

VMDK vs RAR: Key Differences

• •VMDK uses lossless compression while RAR uses lossy compression — this is the fundamental technical difference between the two formats.
• •The switch from lossless compression to lossy compression means you gain significant space savings while accepting minor quality trade-offs.
• •Alpha channel support: RAR lacks transparency support, so semi-transparent pixels from the source will be lost.
• •Storage footprint: Up to 2TB per virtual disk, uses sparse allocation for VMDK vs Smaller than equivalent ZIP archives for RAR.
• •Primary audience: VMDK is built for vmware virtual machines, virtual disk storage scenarios, while RAR focuses on file sharing, compressed archives — pick the format that matches your output requirement.
