I'm trying to set up an SSD as cache, so I can download and transfer data at full speed, but adding an SSD as a cache only delays my problem for a very short time. An SSD, especially modern ones, can handle transferring to many HDD's at once, but Drivepool only seems to transfer to one at a time? So now when I download/transfer files it just fills up the SSD and then I'm back to square one of my downloads/transfers being slowly limited by the speed of a single drive :(. Is there a way to make it so the SSD will transfer out to multiple drives at once?
