Right-click on the volume and choose Format. Smaller stripe size for random access OS applications larger stripe size for data large files storage. All I can say is that I have a 15GB default sized cluster 4KB boot partition Vista want bootinstall otherwise 285GB Vista and 435GB storage partition both with 64KB cluster and it works very well.

Because you are using SSDs RAID 5 would be an acceptable choice here because SSDs do not have the URE issues that HDDs have and their increased speed lessens the rebuild time and the performance impact on the array when degraded and rebuilding.
