The issue has appeared on Ubuntu 16.04 with the 4.4.0-28-generic kernel. When doing
sudo hdparm -tT /dev/sde
/dev/sde: Timing cached reads: 8598 MB in 2.00 seconds = 4302.13 MB/sec Timing buffered disk reads: 56 MB in 3.11 seconds = 18.03 MB/sec
Everything seems fine, but when writing into the USB drive the writing speed falls down to 9.34KB/s
