Optimal Cluster Allocation/RAID Stripe Size on SQL 2000

Hello everyone. I am about to add another RAID 1+0 array to my SQL 2000 database. It will be (14) HP Ultra320 Drives, 72 Gig, 15k RPM. It will have the top-of-the-line SA 6404 Controller, with 512 Megs of Battery-Backed Read/Write Cache. It will all be in an MSA3000 Dual-Bus RAID Cage. I will be getting full U320 speed, and that is what this upgrade is all about: SPEED. I am moving one of our main databases from a shared RAID 1+0 array to its own on this new system, and giving it its own dedicated Log array as well.

So now that you have the "environment", the question: What is the optimal Cluster Allocation and RAID Stripe sizes for pure speed in SQL? We have PLENTY (and I do mean plenty) of physical space on the drives, so I am not concerned at all about wasting space due to larger clusters. Most things I have read have said 64K for both the clusters and the stripe, but I have also read a few things recently that recommend 64k for the cluster and 128k for the stripe.

Anyone have any thoughts? I am implementing this tomorrow (Saturday July 1st), so any input is greatly appreciated.

Thanks,
Troy

you won't loose any space at all on the database files, as they are BIG compared to the cluster/stripe size.

optimal is everthing that is multiple of 64K, as that is the page size in SQL Server 2000 (and 2005)
