disk alignment partitioning for SQL performance

KevinK recommends for SQL on Windows Server 2003  to have 64K sector offset for the Data drives.

http://sqlblog.com/blogs/kevin_kline/archive/2008/10/06/how-to-improve-application-and-database-performance-up-to-40-in-one-easy-step.aspx

Ours has 32K as the Starting Offset. Since 64K is multiples of 32K, will that be ok, or is it recommended to change it to 64KB.

thanks

Ours is 122GB.

Vaidas911, did you do it on W 2003 Server?

I thought ours was 32KB, but the it is only 31.5K of metadata.
Ours also W 2003 Server, and yes, 31.5K is standart.

tiago_aviz, it is just not about the stripe size, but  if it will lead to 2 IO ops instead of 1.

We have 100 spindles underneath our LAN, but still the Disk IO has remained the same..
Vaidas911, perhaps you should have gone higher than 64k?
