UCS RAID 5 strip size 128KB - why?

Why the recommendation to use a strip size of 128KB on RAID 5 arrays on rack servers? Per UCS documentation there doesn't appear to be a performance increase until 256KB. The recommendation is here:

Thanks in advance.

There were performance issues observed in servers that were mistakenly shipped with Strip size different that the default 128 KB
