I hope you can help me.

Machine: DELL R710 with PERC H700. 6 x SEAGATE 600GB 15K RPM DISKS

I´m installing this machine for virtualization proposal, i will use Microsoft Hyper-v for that.

I will have 2 RAID Virtual Volumes one for the SO and the other one for machines.

The question is about the better block or allocation  size(both are the same?) config  for large VHD Files.

In the raid config i have "the strip element size", the default is 64kb, may i change?


in windows format option i have "Allocation unit size" may i change the default?

I ran some HDtune test, and seams to be fast with "block size" 1MB size.

sorry for poor english
