I am still amazed how hard you try to defend the current primitive functioning of the cache drive while it could very obviously be way more refined.
If the mover starts moving at 10% capacity left of the cache drive, i could NOT fill the cache drive faster with network uploads (to the server) and internet downloads (on the server) than it is emptying by the data being written to the array. This means the cache drive will always be used to it's (90%) maximum and the array would only be spinned up when necessary. The cache drive will never be completely full and data written to the array will only be done by the mover.
I brought up the network speed argument before and i think since using turbowrite and a new intel network card i actually might be able to write faster to the array over lan than the 400 Mbit/s from before. That point might be mute after testing. If not, it would still be my biggest gripe.
I understand your point about the minimum free setting, it doesn't concern me much though. i transfer files of less than 10-20% capacity of my cache disk.
Before starting with quizzes we should understand each other, meaning you should understand my point. :P
