Need more disk space on virtual server. Should I add more disks on VM and then use Windows to make spanned volumes?

I'm building a new file server. The original data is on a Windows 2003 server along with SAN storage. We're talking around 6-7TB's of data.
I've got storage on our SAN worth around 14TB. So if I wanted to create a new file server with around 10TB available on it, I would need to create large enough disks.
Now, I've been told that adding disks to Windows and then created a spanned volume on there isn't a great idea for performance? Is that true?
I'm running Vmware 4.1 sadly for now, so I know you can only go up to 8mb blocks and then create a maximum 2TB disk size until we upgrade to vmware 5.5 (which we are planning doing within the next 2 months).
Should I wait and upgrade to Vmware 5.5 and then be able to add larger disk blocks? Is that better for performance?
