Should I Install SQL Server 2008 R2 on a VHDX or Pass-through disk

Hi,

I am in going to be setting a virtual server running Windows Server 2008 R2 on my Hyper-V cluster and I will be also adding SQL Server 2008 R2 once the OS is configured. Can you please suggest whether I should setup a VHDX or a pass-through disk? I have read articles online suggesting to use a pass-through disk from my SAN but I also read that since Windows Server 2012, VHDX is as good as a pass-through disk, especially because it will allow to have snapshots taken, unlike the pass-through which will not.

Please advise on whether I should chose a pass-through disk or a VHDX.

Thanks in advance,
