Is it fair to say that one of the basic limitations of foxpro and cached processing is that foxpro issues large packets and does not multi-thread so therefore a single misdirected packet will result in poor performance and file read errors?

Yup..that's hardware. There is probably a utility program that came with your RAID controller that will allow you to set the percentage of read vs write cache. It should be 100% read and 0% write.
