I was recently surprised when my friend using Linux copied around 4GB file to my pendrive, it showed over 200MB/s and was > rapid fast but then we had to wait for background operation to complete for over an hour with absolutely no information on More funny it could stall the whole system or at least good part of it. Pendrive is extreme example but it still exist for any media. Now think what it would be if you run large multiservice server running hundreds of different services and thousands of processes and you get power failure. Only linux make it possible :)
