Cluster Size for Exchange 2010

Is there an optimal cluster size when formatting a hard drive for a E2K10 database.
I saw something where is says: 'The best size for the Exchange 2010 Mailboxes would be 32k NTFS Cluster size, since this maps 1:1 to the Mailbox Cluster Size. Is thsi correct? I have a E2K7 with cluster size of 65,536 kb.

Is it a virt? if so match the cluster size of host storage if not 32 would work best.

Not a virt. Is this specific to E2K10 or does it also apply to E2K7, just curious. thanks again
Well we have run 2007 for a long time and i do not recall the install setting for cluster size being an issue i would think that it has to do more with 2010.  I can not find any concrete evidence for other wise.

Thanks for the info, one final question:
I typically put the data and log files on two separate partitions, but on the same SCSI container. Would it be wise to do this with E2K10 or should the database and logs go on one big partition, and if the logs go on a separate partition should 32k be used as the cluster size for the log files?
