What's the difference in this case between the use of a > ramdrive and the use of a similar-sized cache for a harddisk? That in the case of the system cache, dirty pages will be written to the disk once the cache fills - which would happen very, very quickly with a large update. The disk i/o system has no knowledge that you've deleted the file again, so writes the data even though it 'no longer needs to' by some definition. - Peter
