What is VMDK?

VMware Virtual Disk (VMDK) is the virtual hard disk format for VMware virtual machines, used for guest OS storage.

What is LZ4?

LZ4 files are built around lossless compression. Designed for real-time compression, log files, game assets, they use the application/x-lz4 MIME type and typically range from varies by content.

When Should You Use VMDK vs LZ4?

Use VMDK When...

Reach for VMDK when your priority is vmware virtual machines, virtual disk storage — its uncompromising quality ensures every detail is preserved.

Use LZ4 When...

Reach for LZ4 when your priority is real-time compression, log files, game assets — its uncompromising quality ensures every detail is preserved.

VMDK vs LZ4: Key Differences

•VMDK uses lossless compression while LZ4 uses lossless compression — both take the same approach to file size management.
•Since both VMDK and LZ4 use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
•How transparency is handled: LZ4 supports transparency, so alpha information is preserved during conversion.
•Storage footprint: Up to 2TB per virtual disk, uses sparse allocation for VMDK vs varies for LZ4.
•Use case fit: VMDK targets vmware virtual machines, virtual disk storage and LZ4 targets real-time compression, log files, game assets — your choice depends on which workflow stage you are serving.
