When Should You Use TGZ vs VMDK?

TGZ vs VMDK: Key Differences

• •The core technical difference: TGZ relies on lossy compression whereas VMDK uses lossless compression.
• •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
• •Alpha channel support: VMDK lacks transparency support.
• •TGZ files are typically Same as .tar.gz archives while VMDK files range Up to 2TB per virtual disk, uses sparse allocation
• •TGZ is optimized for unix/linux software source distribution while VMDK is designed for vmware virtual machines, virtual disk storage — choose based on your specific workflow needs
