VMware Virtual Machine Split Disk

Posted on 2014-08-12

When Creating New VM, we get to choose between split disk files or just one disk file.
I wonder what are the pros and cons of opting for one or another.

Like on some VMs , I selected Split disk files, and now I can see the files like having multiple snapshots of the VMs, though I have not done any snapshot.

Any idea?

    Split disk allows you to easily copy the files from computer to computer, and allow file system which do not support large file sizes, e.g. FAT32 limits.

    However, there is a danger, many files, a file could get corrupted, or copying a file, could be lost or missing.

    Performance is poor.

    Single disk performs better, but you may have issues, with transporting such a large file, not an issue with NTFS and external NTFS hard drives.

    It's up to you, want you want to do with your VMs, but we use single disk files, and allocate space now.

    I do not see the scenario when you will copy files from one computer to another as you stated..
