Please make it so you don't have type "sync" after saving a file to a USB, ie. the write is AUTOMATIC, not delayed. Thanks very much.
You want to disable disk caching by default?!
You can change your own settings, but when talking about defaults, you gotta try to think of general case. Most people like caching, myself included. If I need to remove a usb drive, I look to see if its led is flashing (most of mine hae LEDs) or I unmount it. I'd much rather have to do that (or type sync) when I want to remove a drive and have my computer seem fast when I write to disk, than have it be slow all the time.
So I vote no, this would not be a good idea for deafult imo. Unless I completely misunderstand your proposal.
