Both have had problems since using the C connector with the tablet. At first it worked fine, but then it started slowing down when writing files; drops to 9-10 KB/sec. The USB port continued to function with read speeds of 35 to 40 MB/s (never faster). Then, over time, the USB transfer speed also dropped to horribly slow read and write speeds. The same goes for both drives. I hard reformatted the drives and restored the read and write speeds to acceptable (but not high) rates.
