If write-caching is disabled, is it truly unnecessary to click "Safely Eject Hardware"?"
That is my interpretation.
"If so, that's a big time saver! ...what if you have a file open/in use that's stored on the Jump Drive at the time you pull it?"
The only time saver part of it would be the disconnecting. The actual writing would be slower without "write caching", I imagine?
Any disconnection while in use would be fatal, watch for any flashing lights to indicate use.
