Thanks for bringing this up , never thought about this but it ' s something I shall think of for the future ! My opinion is yes too <| sep |> Awesome . Kap has finally turned in to a College Sophomore . At almost 30 years old <| sep |> Windows does Disk Write Caching in memory by default , but also tries to flush those writes to disk as fast as possible you can turn off this behaviour if you really want toknow what you ' re doing . That ' s why you see a writes to the drives after a copy operation finishes , as the copy operation is done as soon as everything is written to memory , but disk activity ceases only when the write buffer has been flushed to disk . This is a higher level of what RAID controllers with write caches do , only they confirm the writes to the OS as soon as they ' ve entered the write cache and not when they are actually written to disk .
