ESXi Block size question

I just created a new 1.5TB LUN on my SAN to be used for my file server. I'm adding it in vCenter right now, and before I choose a block size, I thought I'd pop on over and ask you fine folks if I have any real option on block size besides 8MB, since I want to make a single 1.5TB volume.

Is this my only choice? Would I be better off creating a small sized file or LUN?

While it's possible for me to have different drives on my server (Windows 2008 R2), I'd prefer to keep everything on one drive/ partition. Thanks to everyone for your help.

block size dicatates the max size of virtual disk

an 8MB block size max virtual disk is 2TB-512bytes

so what size virtual disks are you planning

we usually create 500-800GB LUNs with 5 virtual disks per LUN, unless you need a super LUN for large virtual disk

I was hoping to create a single 1.5TB disk on this LUN (and nothing more) for my file server data. I'm wanting a second opinion that I'm not nuts in doing that. I'm still fairly fresh to VMware.
