Lets say ive run extensive tests with SQLIO and found for my particular workload the ideal blocksize is 64kb.

I ran the command fsutil fsinfo ntfsinfo T: and can see the drive currently has a cluster size of 4kb.

Should i now reformat the drive with a cluster size of 64kb?

Im pretty sure thats what i do, but i just want to be certain.

As far as I know you need to reformat the disk.

Also, Depending on the size of the disk you may want to consider using GPT over MBR.
