Jawaid,

I own a RAMfast SCSI card, and your statement conflicts directly with my
experience, and my discussions with CV Technologies.   When I write data to
disk, there is often a delay between when the program starts writing data, and
hard disk activity.    The cache on the Ramfast is not a write-through cache.  
The card is Very fast so the delay is never more than a second or two, but it
is there.
