[EDIT]: * PC hard drive is an SSD as well (upgraded 2 years ago). * Transfer speed from internal SSD to external SSD. (See attached image) ** declared: 40MB/s ** observed: 12kB/s (I hand measured 87sec/1MBs) ** slowing factor: 3000+ * Dirty little hack : unmount then remount external disk hack did NOT work when done over heavy 457MB GIS file. Likely over flooded the cache as it started.
